Vcenter Server Alarm overall health changed from 'Yellow' to 'Red'

Dear All,

I received one email trigger today as below:

Target: Datacenters

Previous Status: Gray

New Status: Red

Alarm Definition:

([Event alarm expression: vCenter Service Overall Health Changed; Status = Red] OR [Event alarm expression: vCenter Service Overall Health Changed; Status = Green] OR [Event alarm expression: vCenter Service Overall Health Changed; Status = Red] OR [Event alarm expression: vCenter Service Overall Health Changed; Status = Yellow])

Event details:

vCenter Service overall health changed from 'yellow' to 'red'

But when I log in to vcenter there is no alert there. How I can confirm that vcenter is normal and the reason why this alarm was triggered. Please assist.

No, we did not do any update. The vcenter is not member of any domain controller from the beginning. No, changes are done.

thank you,

For the "health status" error, you may check: VMware KB: vCenter Service Status page alerts: Unable to retrieve health status

Have you checked if the services (license and the profile-driven storage one) are actually running? Maybe those died for some reason.

Hello,

I just restarted the vcenter server, Now I checked and seeing those same services in green:

I will see its behavior for 3/4 days, but do you have idea it is now fixed OR still not will go back to red again. Any verification. After re-start I got this email below:

Target: Datacenters

Previous Status: Red

New Status: Yellow

Alarm Definition:

([Event alarm expression: vCenter Service Overall Health Changed; Status = Red] OR [Event alarm expression: vCenter Service Overall Health Changed; Status = Green] OR [Event alarm expression: vCenter Service Overall Health Changed; Status = Red] OR [Event alarm expression: vCenter Service Overall Health Changed; Status = Yellow])

Event details:

vCenter Service overall health changed from 'not available' to 'yellow'

I would first wait for a while if it happens again. Status is still "yellow" so mabye you check other locations in vCenter if there are problems/warnings reported.

Hello,

I checked today, I don't find any thing red as sent screen shot yesterday. Also no email, How can I check check what is the current health of vcenter, green, yellow. One more question on same token can I configure alarms to send email notifications if host failure occurs ? the host which failed will be able to send alarm notification ?

thank you,
