Which command is used to restart the Splunk service?

The command used to restart the Splunk service is "splunk restart." This command is part of the standard suite of commands provided by Splunk and is specifically designed to initiate a restart of the Splunk platform, encompassing both the search head and the indexer, depending on the deployment type.

When you execute "splunk restart," it gracefully shuts down the Splunk service before starting it again. This ensures that any changes made to configurations or updates applied to the system are taken up into account during the restart process. It is a straightforward command that system administrators can use without needing to specify additional options or parameters, making it user-friendly.

Other commands listed may perform different functions; for instance, the "splunk service restart" command does not exist in the correct syntax for Splunk operations. "Splunk btool" is utilized for configuration file management and validation rather than service control, and "splunk system restart" is also not recognized by the system as a valid command. Thus, "splunk restart" accurately fulfills the requirement to restart the Splunk service effectively.
