Part of alerts from Alertmanager not displayed

[dragoangel]

Nagstamon 3.10.1 on Windows (and may be on other OS) have a bug: if in Alertmanager you have severity that you not configured in Alertmanager server properties in Nagstamon then not only this alert will not be displayed, but also alerts "after" this alert will be missing.

F.e.:

• alertmanager have 6 firing alerts, 2 with severity warning, 2 with critical and one with none and one with info
• in this case with default configuration of alertmanager in Nagstamon you should see 4 alerts (2 warning and 2 critical)

But due to bug you could not see part this 4 alerts. If you configure alertmanager in Nagstamon to understand none and info severity you will all 6 alerts as should.

Hi, I installed latest version, removed none from Map to UNKNOWN, and my alerts with severity="critical" was hidden. Adding back none reveal my critical alert back. severity=none is default severity in kube-prometheus-stack for Watchdog and InfoIngibitor alerts by default there is no such severity in Nagstamon. Maybe we can add Map to HIDDEN alerts and by default list there none as it is usually used to hide alerts properly 😊.

Also:

• I'm not 100% sure, but Map to OK isn't needed on alertmanager as API does not contain resolved alerts, right?
• Map to status_information for alertmanager and prometheus from my view better looks in this order for new server instances: message,description,summary, as usually summary not contain enough details, what do you think?
• https://github.com/HenriWahl/Nagstamon/issues/723 is very important to be implemented. It is not a problem to see a bit mess after alertname compared to missing alerts.
