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.
