Are Alerts and Reports Global or specific to that Search Head?

[Gregski11]

For example if there are two Search Heads and I go to Settings \ Searches, reports, and alerts on Search Head 1

and I list all the Alerts am I looking at all the Alerts in our Splunk Environment or only the ones running on this Search Head

I'm asking cause we have so much stuff running that no one is looking at, that I want to start Disabling some Alerts in order to increase performance

I know that one Search Head belongs to my group and the other one to another group of Splunk users so I want to turn off Alerts on our Search Head only and not for everyone 

I hope this makes sense, thank you

If the SHs are part of a cluster then the list should be global.  Any searches that are part of a locally-installed app (not pushed from the SHC Deployer) will be specific to that SH.

If the SHs are independent then the list is specific to that SH.
