How do I calculate the Enterprise security App license usage ? Is it different from the Spunk Enterprise license ? Does the ES app use the base indexes of Splunk Enterprise or does it contain separate indexes ?
Question - How to calculate the Enterprise security App license usage ?
As per my understanding - Splunk ES is an app that sits on top of base Splunk. so, you need license for Base Splunk, that is enough.
As per below link also, Splunk Enterprise Security is a Splunk Premium Solution, which requires a Splunk Enterprise license or Splunk Cloud subscription.
Splunk Enterprise Security software is priced by how much data you send into your Splunk installation in a day.
