To provide predictive maintenance. Does the App Splunk Essentials for predictive maint. # 4375 installed on each server individually? Thank u very much for your reply in advance.
The app's splunkbase page says
Install the Splunk Essentials for Predictive Maintenance app on a test instance separate from production infrastructure.
so it would seem it is to be installed in one place. The description of the app reads like it's intended to be a tutorial. Once you've used the app to learn to do predictive maintenance you apply your new skill on another (only one, I surmise) instance.
