Products by Splunk

One of the formidable elements in any Splunk tutorial is the outline of different products offered by Splunk. Presently, Splunk is available in three specific versions, such as Splunk Enterprise, Splunk Light, and Splunk Cloud.

Splunk Enterprise is the chosen favorite of many large IT enterprises, and it helps in the collection and analysis of data from various applications, websites, and data sources.

Splunk Light is the free version that helps you gain your first insights into the world of Splunk. Users can leverage Splunk Light to judge the capabilities of Splunk for searching, reporting, and altering their log data. However, Splunk Light comes with limited features as compared to the other versions.

Splunk Cloud works as a hosted platform with the same features as Splunk Enterprise. Users can access Splunk Cloud directly from Splunk or through the AWS Cloud platform.

Splunk Architecture

Among all the concerns for Splunk training, the architecture of Splunk always grabs the top spot. A clear understanding of the basic components in Splunk architecture is an essential requirement to develop fundamental knowledge about Splunk. Here are the important basic elements in the architecture of Splunk.

  • Universal Forward (UF) is a lightweight component for pushing data to the heavy Splunk forwarder. Users can install the Universal Forward on the application server or client-side. The work of the Universal Forward is the forwarding of log data.
  • The Load Balancer (LB) in the Splunk architecture serves as the basic Splunk load balancer. In addition, it also allows the use of a personalized load balancer.
  • Heavy Forward (HF) is also one of the important aspects of the Splunk architecture you would find in a Splunk tutorial. Heavy Forward is a heavy component and allows the filtering of data effectively. The example of the use of HF is evident in the collection of only error logs.
  • Indexer is also one of the significant aspects of the architecture of Splunk. It is ideal for the storage and indexing of data and contributes substantially to the improvement of Splunk search performance. Splunk automatically provides the functionality of indexing by default, such as in the examples of date and time, host, and source.
  • The Search Head (SH) is also one of the important additions in the discussion on architecture in a Splunk tutorial. It is helpful for improving intelligence alongside ensuring the execution of reporting activities.
  • Deployment Server (DS) is a crucial component in the Splunk architecture that supports the deployment of specific configuration. An example of the use of Deployment Server (DS) is the update of the UF configuration file. Deployment Server can also support sharing between different components.
  • License Manager (LM) in the architecture of Splunk enables effective monitoring of the license on the grounds of usage and volume. Splunk provides regular reviews of licensing details to ensure the authenticity and relevance of the functionalities of Splunk.

Working of Splunk

Based on an overview of the components of Splunk architecture, you can develop a generic impression of how Splunk works. The three basic components to understand the working of Splunk are the forwarder, indexer, and the search head. The Forwarder ensures the collection of data from remote machines and then forwarding the data to index in real-time. Then, the Indexer ensures the processing of the input data in real-time.

In addition, the Indexer also stores and ensures the indexing of the data on disk. The final important component for understanding the working of Splunk in a basic Splunk tutorial is the Search Head. The Search Head is basically the interface that allows users to interact with Splunk and use its functionalities. Search Head enables users to perform the search, analysis, and visualization processes.
