Thanks! I think what you are changing should actually stay as "alerts" since the dropdown is listing alerts. In "setup mode" we display the rules we would need to toggle between "rules" and alerts" instead of just having "alerts" everywhere.

Should be "rules" (setup mode)

Should stay "alerts" (not in setup mode)

Part of the change is here https://github.com/elastic/kibana/blob/master/x-pack/plugins/monitoring/public/alerts/badge.tsx#L21, but would require usage of the variable inSetupMode to show "rules" vs "alerts".

@ravikesarwani do you agree?

Could have someone on the team do it if you prefer.

[ravikesarwani]

I agree @neptunian . In "fired/active" state we need to refer to it as Alert.
In setup mode we need to change it to say Rules.

Thanks for the feedback @ravikesarwani and @neptunian !
I've updated this PR so that it contains only the documentation changes and have had a go at the code changes you suggested in
#102441

Thank you so much @lcawl. I reviewed the help available here Kibana alert docs. One piece that has caused confusion to the users is around how to review and modify threshold etc. on the default rules that we have created.
Can you please add the following line to make this clear in the help =>
To review and modify all the available default rules, use Enter setup mode on the Cluster overview page in Stack monitoring.

This can be added potentially as a Note after "However, you can tailor them to meet your specific needs." so that it's highlighted. Thoughts?

[lcawl]

@ravikesarwani Yes, that's the piece of info that was accidentally omitted from the previous PR. You can see it now in the preview here: https://kibana_101977.docs-preview.app.elstc.co/guide/en/kibana/master/kibana-alerts.html
