Step-by-step explanation:
The splunk offline command in Splunk is used to take a Splunk instance offline, suspending regular indexing and searching operations. This can be useful for performing system maintenance, upgrading Splunk, or troubleshooting issues. When the splunk offline command is executed, it stops data collection, processing, searching, and indexing.
During the offline mode, users will not have access to real-time data and the Splunk instance will not process any new data. However, all the previously indexed and archived data remains available for search and analysis.
To bring the Splunk instance back online, the splunk start command can be used.
