Is it the maintenance of "Splunk Enterprise"? Or is it a deployment server maintenance?
Splunk does not need maintenance in particular, and I think that it is enough to restart the server at regular intervals.
If you need advanced performance, please refer to the administrator's manual etc.
Capacity Planning Manual
Optimize Splunk for peak performance
Splunk Sizing and Performance
Thanks for sharing!
To answer your question, i would say for both.
So that would mean a that if the hardware and software are performing well and being maintained on a regular basis, Splunk Enterprise will be ok already?
