Where is rapid diag?

[Gregski11]

So we are seeing some error pertaining to our cluster master being an unhealthy instance, we have a link called Generate Diag but when we click it the message reads: The app "splunk_rapid_diag" is not available

we are on version 9.0.0 of Splunk Enterprise, the following Splunk Documentation says how to get to it, but we do not see that option

https://docs.splunk.com/Documentation/Splunk/9.0.0/Troubleshooting/Rapiddiag

How do I access RapidDiag?

The RapidDiag UI is located in the Settings menu, under System > RapidDiag.

Better late than never 😉

Since I had the same issue:
From the documentation Using RapidDiag - Splunk Documentation

• The RapidDiag app is available on Linux-based Splunk Enterprise installations only.

Since I was running splunk on windows, that explains it for me.
