What is the purpose of Splunk?
Splunk software explores, evaluates, and converts data during the Parsing phase to extract only the relevant data. It is also referred to as process automation. Splunk software splits the data stream into single events during this phase. The parsing phase is divided into several sub-phases:
Why is Splunk important?
Splunk processes incoming data to allow for quick search and analysis. It improves the data in a variety of ways, including:
What is Splunk indexer?
The indexer is the Splunk component that will be used to index and store the data from the forwarder. The Splunk instance converts incoming data into events and stores it in indexes for efficient search operations. If the data is received from a Universal forwarder, the indexer will first parse it before indexing it. Data parsing is used to remove unwanted data. However, if the data is received from a Heavy forwarder, the indexer will only index the data.
What is Splunk metadata?
Splunk software uses up the raw stream of data from its own origin, divides it into 64K blocks, and analyzes each block with metadata keys during this stage. The metadata keys also include data's hostname, source, and source type.The keys can also contain values being used internal and external, like the data stream's character encoding, and value systems that control data analysis during the indexing stage, like the index into which the events should be stored.
What is the Splunk search function?
Splunk application stores consumer knowledge objects, such as documents, event types, dashboards, alerts, and field extractions, as part of its search function. The search function is also in charge of managing the search process.
What is Splunk software?
With Splunk software, it is simple to search for specific data within a cluster of complex data. It is difficult to determine which configuration is currently active in log files. To clarify, the Splunk application employs a tool that assists the user in locating issues with a configuration file and viewing the current configurations that are in use.
What is the purpose of Splunk's indexing phase?
During the Indexing phase, Splunk software needs to write parsed events to a disk index. It saves both of the condensed raw data and the index file. The advantage of indexing is that the data is easily accessible during searching.
What are the components of Splunk?
The primary components in the Splunk architecture are the forwarder, the indexer, and the search head.

Why use cluster indexers in Splunk Enterprise?
In Splunk Enterprise, you can set up a cluster of indexers with replication between them, to avoid data loss and provide more system resources and storage space to handle large data volumes.
How does Splunk work?
There are two main ways to use Splunk for data analytics—Splunk Enterprise that collects log data from across the enterprise and make it available for analysis, and Splunk Hunk that indexes and makes queries of Hadoop data, creates dashboards and reports directly from Hadoop datasets.
How does Splunk store logs?
Data Storage – Splunk parses log data, by breaking it into lines, identifying timestamps, creating individual events and annotating them with metadata keys. It then transforms event data using transformation rules defined by the operator. Finally, Splunk writes the parsed events to disk, pointing to them from an index file which enables fast search across huge data volumes.
What is data input in Splunk?
Data Input – Splunk ingests the raw data stream from the source, breaks it into 64K blocks, and adds metadata keys, including hostname, source, character encoding, and the index the data should be stored in.
What is a search head in Splunk?
The search head provides the UI users can use to interact with Splunk. It allows users to search and query Splunk data, and interfaces with indexers to gain access to the specific data they request.
What is a Splunk search?
In a Splunk instance, a search head can send search requests to a group of indexers, or search peers, which perform the actual searches on their indexes. The search head then merges the results and sends them back to the user. This is a faster technique to search data called distributed searching.
What is the search function in Splunk?
As part of the search function, Splunk software stores user-created knowledge objects, such as reports, event types, dashboards, alerts and field extractions. The search function also manages the search process.

What is Splunk indexer?
Indexer is the Splunk component which you will have to use for indexing and storing the data coming from the forwarder. Splunk instance transforms the incoming data into events and stores it in indexes for performing search operations efficiently.
What is metadata in Splunk?
In this stage, Splunk software consumes the raw data stream from its source, breaks it into 64K blocks, and annotates each block with metadata keys. The metadata keys include hostname, source, and source type of the data. The keys can also include values that are used internally, such as character encoding of the data stream and values that control the processing of data during the indexing stage, such as the index into which the events should be stored.
