Icinga2, the next generation, complete rewrite, of the Nagios fork Icinga, is an open source monitoring system which checks the availability of your network resources, notifies users of outages, and generates performance data for reporting.

Icinga 2 manages monitoring tasks, running checks, sending alert notifications. The Icinga 2 features can be enabled on-demand, be it default features such as the 'checker' or 'notification' component, or external interfaces compatible with Icinga 1.x and its user interfaces, for example the IDO DB (Icinga Data Out Database). Icinga 2 ships a built-in cluster stack secured by SSL x509 certificates attempting to make distributed monitoring setups more easy.

The configuration syntax is different to Icinga Core 1.x and Nagios and requires a migration on upgrade.

hide "Recently Recovered Services" from "Current Incidents" dashboard in Icingaweb2

All we want to see is critical issues and warnings in the default dashboard. We don't care about seeing recently recovered anything. Do I need to install Dashing for this sort of thing?

icingaweb2 authentication php error

Yesterday I added the below mpm config to httpd.conf and restarted Apache. I logged in and everything was fine. This morning Icingaweb2 auth is broken. I doubt the mpm module has anything to do with the php error but that's all I changed.
