Which command is used to restart a Splunk instance?

The command used to restart a Splunk instance is "splunk restart." This command is specifically designed to initiate the restart process for the Splunk service, ensuring that any changes made to configurations or updates are applied. When executed, it gracefully shuts down the Splunk application and then starts it again, maintaining the state and data integrity during the procedure.

Moreover, the syntax "splunk restart" is a part of Splunk's command line interface, making it the most appropriate command for this action. Other commands listed do not correspond to the correct syntax or functionality recognized within the Splunk environment. For example, "start command" and "run command" do not provide any context for restarting or controlling the operation of the Splunk instance. The "restart command" might sound logical, but it is not an actual command available in the Splunk CLI. Therefore, using "splunk restart" is essential for effectively managing the lifecycle of a Splunk instance.
