Guidance Required on Alert Status Display in Alertmanager

[kaushal...@gmail.com]

Hi,

I have configured the latest versions of Prometheus and Alertmanager in Ubuntu LTS OS 24.04 . Is there a way to configure the green button to display ACTIVE when the service is up, instead of INACTIVE, and the red button to display INACTIVE when the service is down, as shown in the attached screenshot for your reference?

# prometheus --version
prometheus, version 3.5.3 (branch: HEAD, revision: dcd3d551ced8b8dc14e0217f8cb14e547109cd5f)

Could you please guide me on how to achieve this configuration, or let me know if this behavior can be customized?

Dear Mr. Kaushal,

I was quite surprised to receive your reply, as I had nearly forgotten that I had sent an inquiry email to the Prometheus mailbox.

Please accept my sincere apology: I am no longer responsible for the back-end technology position due to work adjustments. Nonetheless, I greatly appreciate your response.

Not really, because it's referring to the alerting rules, not any particular service.

An alerting expression which returns an empty vector is an inactive alert rule. Similarly, when the alerting rule returns a vector of one or more alerts, that means the alert is active.

Neither state tells you anything about how many services are being monitored.  You might not have any services that could ever match a given rule; the rule remains inactive, but that doesn't imply that there's any corresponding service which is active. It would therefore be misleading to label "Active" here. The absence of an error does not imply the presence of something which is good.

Of course, it's all open source and you can hack it however you like, but then you'd be maintaining your own fork of Prometheus forever.
