This machine data contains a wealth of important information that may be used to improve the efficiency, productivity, and visibility of a company’s operations.

Splunk was developed in 2003 with a single goal in mind: to make sense of machine generated log data. Since then, there has been an increase in the need for Splunk expertise. In this blog, I have provided answers to two often asked queries by non-Splunkers:

  • Why is it necessary to utilize Splunk? What is the process through which it eliminates my problem

What is Splunk used for: The Machine Data Challenge

Take a look at the graphic below to get a sense of what machine data looks like. Now assume you’re a SysAdmin attempting to find out what went wrong with your system’s hardware and you come across logs like the ones shown in the image above. What would you do if you came across logs like the ones shown in the image above? Would you be able to pinpoint which stage in the process your gear failed to perform? A remote possibility exists that you will be successful, but even then, you will only succeed after spending hours deciphering the meanings of each word.

  • It is difficult to comprehend
  • Due to the unstructured nature of the data, it is not suited for analysis or visualization.

This is where a tool like Splunk may be quite useful. Alternatively, you may provide the machine data to Splunk, which will take care of the dirty job (data processing). Once it has completed processing and extracting the essential data, you will be able to quickly identify where and what the issues were. Initially, Splunk operated in this manner, but it gained prominence with the introduction of Big Data. Because Splunk is capable of storing and processing enormous volumes of data, data analysts such as myself began submitting large amounts of data to Splunk for analysis.

What Is Splunk?

In its most basic form, Splunk is a software platform that searches, analyzes, and visualizes machine-generated data collected from your IT infrastructure as well as from your business’s websites, apps, sensors, and other devices. What would you do if you have a machine that generates data on a continuous basis and you want to assess the machine’s condition in real time? How will you go about it? Is it possible to complete the task with the assistance of Splunk? Yes! Yes, you can. The illustration below will assist you in understanding how Splunk collects data.

There has been no improvement in this approach, and it remains the bottleneck in the majority of organizational procedures.

  • Your input data can be in any format, for example, csv, json, or any other format you like. You can enable Splunk to send Alerts / Events notifications at the commencement of a machine state
  • However, this is not recommended. You have the ability to precisely forecast the resources required for infrastructure expansion. You have the ability to develop knowledge items for Operational Intelligence purposes.

It is important to understand what a knowledge object is for those of you who are unfamiliar with the term. A knowledge object is a user-defined entity that allows you to augment your current data by extracting some relevant information. These Knowledge objects can include stored searches, event kinds, lookups, reports, alerts, and a variety of other items that assist in the configuration of intelligence for your systems and applications. Some of the functions that Splunk may be used for are highlighted in the infographic to the right.

They used Internet of Things (IoT) devices to collect healthcare data from patients who were stationed in different locations (sensors).

Using Splunk, this data would be processed, and any anomalous behavior would be communicated to the doctor and the patient through the patient interface. They were able to do the following thanks to Splunk:

  • The ability to report health concerns in real time
  • Investigate the patient’s health record in greater depth and look for trends
  • When a patient’s health begins to deteriorate, an alarm or alert is sent to both the doctor and the patient.

Splunk Light is a free version of the software. It gives you the ability to search, report, and modify your log data. The functionality and features are restricted when compared to the other versions.

Splunk Architecture

Now, in this Splunk foundations course, we will learn about the Splunk architecture, which includes the following components: Architecture of Splunk Here are some of the most important components of the Splunk architecture:

Universal Forward (UF):

Splunk forwarder, also known as Universal Forward (UF), is a lightweight component that delivers data to the heavier Splunk forwarder. Universal Forward can be installed on either the client or the application server. The only responsibility of this component is to convey the log data.

Load Balancer (LB):

The default load balancer for Splunk is named Load Balancer. It does, however, let you to make use of your own customized load balancer.

Heavy forward (HF):

A heavy forward is a significant component of the team. This Splunk component allows you to filter the data that is being shown. For example, just error logs may be collected.

Indexer (LB):

Indexer is a tool that assists you in storing and indexing data. It enhances the performance of Splunk’s search engine. When Splunk is started, the indexing is completed automatically. For example, host, source, and datetime are all valid values.

Search head (SH):

The search head is used to gather intelligence and to provide reports for the organization.

Deployment Server(DS):

The configuration is deployed with the assistance of the deployment server. For example, you might make changes to the UF configuration file. We can use a deployment server to communicate information amongst the components, and we can utilize the deployment server to share information.

License manager (LM):

The license is dependent on the amount of data that is used — for example, 50 GB per day. Splunk verifies the licensing information on a regular basis.

How Splunk Works?

Now, in this Splunk training session, we will study how Splunk operates in the following ways: Splunk’s Operational Principles


In real time, the Forwarder collects data from faraway devices and sends it on to the Index through the Internet.


The indexer is responsible for processing the incoming data in real time. It also stores the data on disk by indexing it.

Search Head:

The Search Head is the interface via which end users interact with Splunk. It enables users to do searches, analyses, and visualizations.

Applications of Splunk

The problem was that MacDonald did not have a clear understanding of which offers were the most effective.

  • Offer type (for example, a 20 percent discount)
  • Regional cultural variations
  • Time of purchase
  • Device utilized by the buyer
  • Revenue earned per order
  • And other factors.

They required information on consumer behavior and response from customers. The entire procedure is based on three different sorts of data sources.

  1. Orders placed at a MacDonald’s outlet
  2. Orders placed using the Mobile Application
  3. Orders placed through the Web Application

Afterwards, the procedure progressed from one phase to the next, as depicted in the following diagram:


The input data is sent to the parsing stage.


It is at the Parsing Stage that relevant data is transformed into events:

  • Time of Order (morning, afternoon, evening, night)
  • Customer Region
  • Revenue per order
  • Customer Type
  • Customers’ preferred device (mobile, PC, or tablet)
  • Discount Coupons are applied
  • And

Indexing stage

During this step, events are sorted and indexed for storage on the basis of the following criteria:

  • Revenue generated from orders placed at various times (morning, afternoon, evening, and night)
  • Devices used by customers
  • Coupons that were applied
  • Sales by geographic region

Search Head

It is used to gather intelligence as well as to provide reports. It was used by MacDonald to obtain the following information:

  • Identifying which sales offer is most effective in which geographic region
  • Customer behavior has an impact on order revenue
  • How does this change? I’m wondering when the optimum time is to use burger or combo offerings.

How Splunk Helped?

  • In real time, display all of the orders coming in from throughout a given geographic region. Find out how different promotional offers are affecting your business in real time
  • Mac Donald’s in-house developed point of sale systems are being monitored for performance. An employee may listen in on what consumers are saying and assist them better grasp their expectations of the company. We investigated the processing times of several payment methods
  • Decide on a payment mechanism that is error-free

Best Practices of using Splunk

  • You should test the index in order to be able to complete the test rapidly
  • There are several fields that must be perfect when it comes to indexing. Everything else can only be created or modified once the indexing process has been completed. Because event breaking occurs automatically in Splunk, it is vital to verify that the beginning and conclusion of an event were accurately recognized
  • Splunk can automatically identify the time stamp. You will need to configure the timestamp if your log format has a different timestamp than the default one.

Want to know everything there is to know about ‘What is Splunk?’ Take a look at this comprehensive Splunk Tutorial! Due to the fact that you have learned about Splunk, let us now explore Splunk’s history in the next part.

A Brief History of Splunk

Rob Das and Eric Swan co-founded this technology in 2003 as a response to all of the questions that were generated when researching the information caverns that were being faced by most businesses at the time. “Splunk” is derived from the term “spelunking,” which refers to the exploration of information caverns in a cave system. It was created as a search engine for the log files that are stored in the infrastructure of a system, and it is now in beta testing. After its initial release in 2004, Splunk received a resounding positive response from end users.

The primary objective of the company’s founders is to commercialize this evolving technology in large quantities so that it may be used in virtually any type of application scenario.

The characteristics of Splunk will be discussed next.

Splunk Features

Here are a few examples of the functions for which Splunk is being utilized: Get a better understanding of ‘What is Splunk?’ with this Splunk Training to help you advance in your profession! After gaining a thorough grasp of Splunk’s functionality, we’ll go on to discussing the pros and downsides of using Splunk.

Advantages and Disadvantages of Using Splunk

As described by an IT Central Station user, some of the most notable characteristics of Splunk include ‘its speed, scalability, and, most crucially of all, the inventive style with which it collects and presents the data.’ When it comes to setting up and adding new sources, on the other hand, the same user complains that Splunk might be difficult to navigate. The following are some of the benefits of utilizing Splunk:

  • Splunk generates analytical reports that include interactive charts, graphs, and tables, and it allows users to share these findings with others, making them more productive. Splunk is a scalable and simple-to-implement search engine. Splunk can automatically discover relevant information included within your data, saving you the time and effort of identifying it manually. It assists in preserving your searches and tags that are identified as vital information, allowing your system to become wiser as a result.

Take a look at some of its downsides as well:

  • When dealing with extremely big data quantities, it might be prohibitively expensive. Search engine optimization for speed is more of a philosophical than a scientific endeavor, hence it cannot be executed in a practical manner. Dashboards are useful, but they are not as dependable as Tableau’s data. The IT industry is always striving to replace Splunk with new open-source alternatives, which is a challenge that Splunk must contend with.

What isSplunk Architecture?

Consider how the strong architecture of Splunk is used to extract the necessary output from the complicated data that has been collected. Let’s begin by taking a look at this straightforward visual description of Splunk’s architecture: Let’s take a look at some of the terminology that are associated with the Splunk architecture:

  • UF (Universal Forwarder): It is a lightweight element that aids in transferring information to a more powerful Splunk forwarder when necessary. The primary responsibility of this element is to simply send the log data received from the server. Universal Forward may be installed on either the client-side or the application-side with relative ease. When it comes to computing, a load balancer (LB) is a tool that improves the distribution of workloads across a number of different computer resources. A load balancer is a network or application traffic distribution component that distributes network or application traffic over a cluster of computers. Heavy Forwarder (HF): It is widely acknowledged to be the most significant aspect. This Splunk component gives you the ability to filter data. If, for example, you want to collect only the error logs, this will be beneficial. Indexer: The primary responsibility of an indexer is to store and index the filtered information. It contributes to the improvement of Splunk’s performance. By default, Splunk provides indexing for hosts, sources, date, and time
  • However, this may be customized. Splunk Search Head(SH): It is a simple Splunk instance that assists in the distribution of searches to the other indexers, and it does not generally have any instances of its own to manage. This software is mostly used to gather intelligence and to generate reports.
  • This server aids in the deployment of configuration, such as changing the UF (Universal Forwarder) configuration file, by distributing it throughout the network. A data sharing system (DS) can be used to communicate information between components. In Splunk Enterprise, a license slave is a state that is governed by a licensing master, also known as a license master. If you just have a single Splunk Enterprise instance, it serves as the licensing manager for the rest of the instances (once you have installed an Enterprise license on it). The license is dependent on the amount and frequency of use. For example, if a user consumes 50 GB per day, Splunk checks the license data on a regular basis.

Learn about all parts of Splunk from this SplunkCourse in Toronto and use it to your advantage in your professional life! The following is an explanation of how the Splunk Architecture works:

  • In this role, the forwarder aids in the collection of data from the basic machines, and then passes that data to the indexer in real time. A real-time indexer is a program that assists in the processing of incoming data. Also included is the ability to collect and organize data stored on a disk. End-users can interact with Splunk through the usage of the Search Head interface. User may do search, analyze, and visualize functions with the help of this program.

Let’s take a closer look at how the Splunk architecture is put together:

  • When data is sent to the indexer, the forwarder can track the data, replicate the data, and conduct load balancing on that particular data before sending it to the indexer. It is possible to create multiple copies of any case at the data source by using cloning, while load-balancing is carried out to ensure that even if one case collapses, the data may be transported to another case that is hosting the indexer. Immediately after obtaining data from the forwarder, it is dumped into an Indexer component. Following that, the data is divided into multiple logical datastores, and at each datastore, you may specify authorities that will govern the user’s views and accesses
  • After that, the data is returned to the Indexer. As soon as the data is in the Indexer, you can begin exploring it and assigning those explorations to different search partners, and all of the results that we will be receiving after assigning will be consolidated and sent on to the Search Head. You may also schedule search buddies and create alarms, which will be activated when certain conditions meet the preset searches
  • You can even run searches on your own time. You may also utilize knowledge objects just to enhance the current unstructured data (data that does not have a specific format)
  • However, this is not recommended. The search heads and knowledge objects may be obtained via the Splunk CLI or the Splunk Web Interface, depending on your preference. Specifically, this contact takes place using a REST API connection.

Is Splunk free?

Having gained a grasp of ‘What is Splunk?’ and its numerous benefits, you may be wondering if Splunk is free of charge. The answer to such question is, of course, affirmative! Splunk is available in a free version called as Splunk Free. It is a completely free version of the software. The free license allows you to index up to 500 MB of data every day, and it has no expiration date. The 500 MB restriction refers to the quantity of fresh data that you can add or index in a single 24-hour period.

Using Splunk Free, for example, you may index 500 MB of data every day and eventually have 10 TB of data stored in the system.

Splunk Free keeps track of your license use and notifies you when a violation occurs.

What is Splunk?

Splunk is a cutting-edge platform that analyzes and indexes log files, allowing enterprises to get valuable insights from the information they collect. One of the most significant advantages of Splunk is that it stores data in indexes rather than in a separate database, which eliminates the need for a separate database to store its information. Splunk is a program that is used for monitoring and searching through large amounts of data. In addition to indexing and correlating information in a container that allows for searchable results, it also allows for the generation of alerts, reports, and visualizations.

Using Splunk for Machine Data Analytics

Splunk assists enterprises in extracting useful information from server data. Compliance and security monitoring are made easier as a result of effective application administration, IT operations management, and compliance monitoring. The engine that powers Splunk is responsible for collecting, indexing, and managing large amounts of data. It can handle terabytes or more of data in any format on a daily basis, and it can do it in any format. Data is analyzed dynamically, with schemas being generated as needed.

Data can be entered into Splunk and quickly analyzed, which makes it a very simple process.

It provides a machine data fabric, which includes forwarders, indexers, and search heads (for more information, see our article on Splunk architecture), which enables real-time collection and indexing of machine data from any network, data center, or IT environment (for more information, see our article on Splunk architecture).

Introduction to Splunk Hunk: Splunk on Hadoop

When it comes to analyzing machine data stored in Hadoop, Hunk is an alternative to Splunk Enterprise that is given and supported by Splunk. A lot of businesses used Hadoop to store and analyze large amounts of machine data in the past since it was the go-to solution for storing and processing very large amounts of data. Organizations are now grappling with the constraints of the Hadoop environment, which is becoming more mature. Source:Splunk Apache Cassandra and Hadoop clusters are both supported by Hunk, a Splunk big data solution that allows users to analyze and display data in both environments.

Source:Splunk Apache Cassandra and Hadoop clusters are also supported by Hunk, a Splunk big data solution built to analyze and display data in both environments. As opposed to writing code in Hadoop for every data-related question you need to ask, Hunk provides an integrated experience that does not require special skills and can help you extract insights from large amounts of data without the need for specialized schemas or a significant amount of development effort. In order to make the most of Hadoop datasets, businesses can use Hunk to achieve the following:

Splunk Hunk Key Capabilities

Hunk is capable of doing the following tasks:

  • Exploring data in Hadoop—explore data interactively across big datasets without the need to examine the structure of the data or develop schemas, and without the need to study the structure of the data. By linking to data from relational databases, it enables users to do deeper research and find abnormalities, uncover trends, and deepen insights. Making sense of Hadoop data by reporting and visualizing it—create graphs, charts, and other visual representations of Hadoop data to make it useful to others in the business. All of the reports may be shared from any device.
  • Configurable dashboards—combine charts, views, and reports to create interactive dashboards that can be accessed on laptops and mobile devices, with built-in security and access control

Should You Use Hunk or Splunk Enterprise?

In the case of Hadoop-stored data, Hunk is the natural choice since it can act directly on the data without the requirement for a large-scale data intake. Although it is possible to extract data from Hadoop, the issue arises as to whether it would be preferable to move from Hadoop and use Splunk Enterprise instead. Hunk’s advantages include the following:

  • When compared to Splunk Enterprise, Hunk often consumes less disk space, resulting in lower storage expenses. It is possible to maintain data in Hadoop in its original format while continuing to utilize tools from the Hadoop ecosystem thanks to the Hunk feature.

The following are some of the benefits of using Splunk Enterprise:

  • Searches in Splunk Enterprise are frequently significantly quicker than searches in Hunk on Hadoop. Searches may be performed in real time, which is not feasible with Hadoop. For long-running searches, latency is often substantially lower than for short-running searches. In contrast to the ease with which Splunk Forwarders can ingest log data from a wide range of IT systems, ingesting log data from various sources on a continuous basis into Hunk can be problematic.

Reduce Splunk Storage Costs by 70% with SmartStore and Cloudian

Splunk’s new SmartStore feature enables the indexer to index data stored on cloud storage services such as Amazon S3, which was previously unavailable. Cloudian HyperStore is an on-premises storage pool that is S3-compatible and exabyte-scalable, and to which SmartStore may join. Using Cloudian, you may isolate computation and storage resources in your Splunk design, allowing you to grow storage resources independently of compute resources. For Splunk Hunk users, HyperStore now has complete Apache Hadoop integration.

Using S3FS as the destination for HDFS, HyperStore allows you to perform Map Reduce processes on top of data stored in a Cloudian appliance, which is a powerful feature.

Splunk – Overview

In machine data and other kinds of big data, Splunk is a program that analyzes and extracts insights from the information. CPUs running web servers, IoT devices, logs from mobile applications, and other similar devices create this machine data. It is not required to offer this information to end users, and it has no functional use in the commercial world. The fact is that they are incredibly vital in order to comprehend, monitor, and improve performance of the equipment in question. Splunk can read data that is unstructured, semi-structured, or perhaps seldom structured, depending on the situation.

With the introduction of big data, Splunk is now capable of ingesting large amounts of data from a variety of sources, which may or may not include machine data, and doing analytics on that data.

Product Categories

In machine data and other kinds of big data, Splunk is a program that processes and extracts information from them. CPUs running web servers, IoT devices, logs from mobile applications and other sources provide this machine data. In order to offer the end-users with this information, which is not required, and which has no commercial significance, They are, on the other hand, vital in understanding, monitoring, and optimizing the functioning of machines. Splunk may read data that is unstructured, semi-structured, or only seldom structured, according to the user’s requirements.

Big data has arrived, and Splunk is now able to process large amounts of data from a variety of sources, including machine data, and to do analytics on this large amount of data (see Figure 1).

Consequently, from its humble beginnings as a simple log analysis tool, Splunk has grown into a generic analytical tool for unstructured machine data and many types of big data.

  • Splunk Enterprise is utilized by organizations with a significant IT infrastructure and a company that is heavily reliant on technology. It assists in the collection and analysis of data from websites, apps, devices, and sensors, among other sources. Splunk Cloud is a cloud-hosted platform that has the same functionality as the corporate edition of the software. It may be obtained directly from Splunk or through the Amazon Web Services cloud platform. All log data can be searched, reported on, and alerted on using Splunk Light, which is accessible from a single location. This edition has fewer functionality and features than the other two versions
  • It is also more expensive.

Splunk Features

In this part, we’ll go through some of the most crucial features of the enterprise edition.

Data Ingestion

Splunk can ingest a range of data types, including JSON and XML, as well as unstructured machine data, such as web and application logs, into its database. The unstructured data can be transformed into a data structure if and when the user requires it.

Data Indexing

Splunk indexes the data that has been consumed to allow for quicker searching and querying under various scenarios.

Data Searching

Using Splunk for search entails analyzing the indexed data in order to generate metrics, make predictions about future trends, and detect patterns in the data.

Using Alerts

It is possible to set up Splunk alerts that will send emails or generate RSS feeds when certain criteria are detected in the data being examined.


Splunk Dashboards may display search results in a variety of formats, including charts, reports, and pivot tables, among others.

Data Model

The indexed data can be modelled into one or more data sets based on specialized subject knowledge, which can then be used to generate new data. In turn, end users who evaluate business cases will have a simpler time navigating the system since they will not have to master the complexities of the search processing language utilized by Splunk.

Uses of Splunk

In order to monitor, search, analyze, and visualize enormous volumes of data, Splunk offers you with an engine that can be used to do these tasks and act on them. It has a broad range of applications, and it supports and operates on a variety of technologies. Splunk is a cutting-edge tool that examines log files that are saved on a computer’s hard drive. It also aids in the gathering of operational intelligence. Splunk may be used for a variety of tasks and does not need the use of sophisticated databases, interfaces, or controls.

Top 10 Uses of Splunk

The following are the top ten applications for Splunk, in no particular order: 1. Search Processing LanguageSplunk provides a search processing language that makes it simple to search for information. Statistical operations may be performed on any given context using this language, which is highly powerful when dealing with massive volumes of data and doing statistical procedures. Consider the following scenario: you may wish to obtain information on the programs that are the slowest to start up and, as a result, make the user wait the longest.

  1. Searching for a specific piece of information is simple and may be accomplished by entering the information below: index=uberagent sourcetype=uberAgent:Process:ProcessStartup |
  2. index=uberagent sourcetype=uberAgent:Process:ProcessStartup Using this method, you may get the precise findings from the log without having to go through the trouble of searching for them.
  3. 2.
  4. Splunk derives this information from the data it gets from a number of sources, such as when a program is started or how long a user has been waiting.
  5. By building a script and directing it to Splunk, you provided the capability of searching for data to the user.
  6. All data that is received may be subject to huge limitations and may include user experiences, application monitoring, and agents.
  7. Splunk applications may be used as data inputs, and they can also be used to display dashboards that show what Splunk has indexed.

Indexes and EventsSplunk takes any and all data instantly once it has been installed.

When it begins looking for information in the data, it also begins doing field extraction.

This aids in the provision of flexibility.

It is completed after indexing is completed, and the incoming data is processed and prepared for storage.


There is no need to manage a backend or create a database while using Splunk because it does all of the work for you.

If one server is not sufficient, another may be readily added, and the data is dispersed evenly among both of these servers as a result.

This does not have a single point of failure because it is scattered across several settings.

Reporting and Notification Splunk can create a number of reports, including graphs, pie charts, bar charts, and other visual representations.

Everything, from statistics to frequency distributions to relationships, may be included in a single report.

This is in addition to the fact that it features an alerting system that assists with log management.

These notifications may be sent by email, RSS feeds, or even a script, depending on your preferences.

Monitoring and Diagnosis have been simplified Keeping an eye on the underlying infrastructure and rapidly identifying the core cause of problems can be tough in today’s age of DevOps.

By glancing at the indexes, it is much simpler to keep track of everything.


Splunk is capable of supporting a wide range of setups.

There is a tool available to make this process easier.

Btool displays merged on disk settings, which may be utilized to debug file difficulties or to examine the values that Splunk is now employing.

Examine the overall functioning of the system With the help of Splunk, a user may keep track of servers or Windows infrastructure.

Each drop down menu also contains text fields, which you may use to enter the information you desire.

Dashboards to view and evaluate outcomes are also available.

A distinct dashboard is provided for each parameter in the system.

10. Organize and retrieve information Using indexing and events, data is kept in Splunk and may be accessed at any time without requiring a login. The logs can be simply watched whenever it is sought for since it can be retrieved from there.


As a result, Splunk is the ideal solution for monitoring various infrastructure performances, troubleshooting issues, creating dashboards, creating reports, and creating alerts quickly and efficiently. A full system management tool, with all logs being kept dynamically, it is available for any system.

What Is Splunk and How Does It Work? • Helge Klein

Despite the fact that you have definitely heard of Splunk, can you explain what it does to a coworker in a few sentences? That is not an easy task. Splunk does not fit into any of the standard categories and instead sticks out from the pack. This makes it more intriguing, but it also makes it more difficult to explain. Here’s my best shot at it.

Google for Logfiles

What should you do if you want information about the current status of a machine or piece of software? You have a peek at the log files. They inform you of the current state of affairs as well as recent events. Great. In the event that you want information on the current status of all devices in your data center, what should you do? If it were possible to look through all of the log files in a reasonable amount of time, that would be the best solution. This is where Splunk comes in to help you out.

It can do a lot more now, but log processing is still at the heart of what the product does.

Search Processing Language

Although you can simply search for simple phrases, like as a username, and check how many times that term appears in a certain time period, Splunk’s Search Processing Language (SPL) provides much more functionality. Statistical Processing Language (SPL) is an exceptionally powerful tool for filtering through large volumes of data and conducting statistical operations on the information that is relevant in a certain situation. Consider SQL on an amphetamine high. Then there’s more. For example, you could want to know which programs are the slowest to start up, causing the end-user to wait the greatest amount of time before starting up.

Initial data is picked by defining a sourcetype (“ProcessStartup”), which stands for “data source type.” As a consequence of this sub-command, the output is piped (“|”) to another command that groups the data by application (“by Name”), calculates the average for each group (“avg(StartupTimeMs)”), and plots the distribution of the results over time (“timechart”): sourcetype=uberAgent index=uberagent index=uberagent The process:ProcessStartup |

timechart avg(StartupTimeMs) by the process name As a result, something like this happens:

Apps, Add-ons and Data Sources

After reading the foregoing, you might be wondering how Splunk knows how long an application has been running. And you are correct in that it does not know anything on its own. However, it may accept information from a wide range of sources, including all types of log files, Windows event logs, Syslog, and SNMP, to mention a few examples. If the information you want is not contained in any logs, you may construct a script and instruct Splunk to digest the output of the script. If that is still insufficient, you should look in Splunk’s App Directory for an add-on that gathers the appropriate data and install it there.

It is independent of Splunk and operates on the monitored endpoints, sending the data it collects to Splunk for storage and analysis.

In the case of uberAgent, both sorts are employed: the physical agent serves as a data input, while the dashboard app displays the information gathered.

Index, (no) Schema, Events

When people hear the word “Splunk,” they immediately think “database.” However, this is a common misperception. In contrast to a database, which needs you to establish tables and columns before you can begin storing data, Splunk takes nearly any data right after it is installed. To put it another way, Splunk does not have a predefined schema. Field extraction is performed at the moment of search, rather than throughout the search process. Although a few of log types are automatically recognized, anything else may be defined in configuration files or directly in the search query.

Splunk indexes every type of machine data that can be represented as text, in the same way that Google crawls any web page without knowing anything about the layout of the site it is crawling.

Typically, events correlate to lines in the log file that are now being analyzed.

Once this is done, the event keywords are entered into an index file in order to speed up future searches, and the event text is saved in a compressed file that is accessible through the file system.

Scalability, (no) Backend

Consequently, we get to the following point: there is no backend to maintain, no database to set up, nothing. Splunk saves data on the file system, rather than in memory. This is beneficial for a variety of reasons: Installation takes only a few minutes. It is available for more systems than I can list here, but the installation process on Windows is straightforward: you simply run the installer, click Next a couple times, and you are finished in less than five minutes. Scalability is a simple concept.

  1. Incoming data is automatically dispersed uniformly, and searches are forwarded to all Splunk instances, resulting in a performance boost that is proportional to the number of computers containing data.
  2. There isn’t a single weak place.
  3. While this is an excellent use case for uberAgent, my point is that this will not occur with Splunk in this situation.
  4. Some monitoring tools only enable you to store data for a limited number of months, weeks, or even days at a time.

Splunk, on the other hand, is a different story. It has the capability of indexing hundreds of terabytes of data every day and storing virtually infinite quantities of data. If you want to or need to compare the speed of user logons from last year with the speed of user logons now, go ahead!

Licensing, Download, Getting Started

If you’re interested in trying out Splunk or uberAgent but aren’t sure where to begin, our installation guide will bring you through the process step by step. In a nutshell, licensing is as follows: The quantity of fresh data that may be indexed by Splunk is limited to a certain amount every day. There is a free version that has a daily limit of 500 MB of data transfer. When purchasing Splunk Enterprise licenses, you are purchasing daily indexed data volume, which is defined in terms of gigabytes that may be contributed to Splunk on a daily basis.

Once the data has been indexed, it becomes your own.
