Azure App Registration secrets and certificates can now be ignored if they expired more than a configurable threshold ago.

This is useful when an expired credential has already been replaced but still appears in Azure — instead of getting a CRIT alert for it, you can suppress it by setting an age limit.

Configure the threshold under Setup > Services > Service monitoring rules > Azure App Registration, in the Check secret credentials or Check certificate credentials section, via the new Ignore if older than option. A credential that expired more than the threshold ago is reported as OK with a brief note.
