These features are missing:
It adds workflow to Splunk and provides a common app with dashboards to search for alerts or events.
Forwarder acting like a dumb agent collects the data from the source. It then forwards it to the Indexer. The Indexer starts by storing the data locally in a host machine or the cloud. Then the Search Head is then used for searching, analyzing, and visualizing the data stored in the Indexer.
The crontab has the commands and scripts that can be run on each server. Using it, you can run one command every hour and another one only once a week.
The different types include:
An index directory is called a bucket which moves through various stages once it ages.

Splunk alerts perform the same role as any other alerts -- you receive a notification triggered on any event. For example, the system will alert if the user enters the wrong credentials multiple times.
Fields can be extracted from event lists, sidebar, or the settings menu via the UI.
You can also write your own regular expressions in props.conf configuration file for extraction.
While Splunk App is a collection of reports, dashboards, alerts, field extractions, and lookups, Splunk Add-ons provide the same information without any visual components or a dashboard.
Log in to the server on which Splunk is installed, rename the passwd file at the below location, and then restart Splunk. When you restart your system, you can log in using the default username: admin password: changeme.
Both are features provided by Splunk to ensure the high availability of Splunk search head if anyone search head goes down.
Search head cluster is a newly introduced feature and will replace the search head pooling in upcoming versions of Splunk.Search head cluster is managed by the captain, and the captain controls its slaves. Compared to search head pooling, search head cluster is more efficient.
You will need first to edit the panels built on top of a dashboard and then modify the panel settings from the UI. This will allow you to choose the colors. This is the preferred way as you can choose whatever colors you want and even assign different gradients and set your values into a radial gauge or water gauge.
Mapreduce algorithm is typically used for batch-based large-scale parallelization, inspired by functional programming’s map() and reduce () functions.
