For Question 1. Yes you should get an email alert when free space, memory usage or cpu usage cross the predefined warning levels. I have see emails for Free Space, but our clusters haven’t had any issues with cpu or memory utilization. Ex.
Example:
Followings warnings are detected:
Health Indicator Details:
Disk Warnings:
-
Detailed Message: Disk volume /usr at 14% free
-
Timestamp: 2025-04-01T16:16:58.468Z
-
Free Space Percentage: 14
For Question 2. The documentation doesn’t specifically call it out. Since it is similar to the email alert, I would guess that it would include the metrics if they are the cause of the cluster health change.
