# Icinga2
**this is very much work in progress**
**Currently only standard checks are supported**, still missing:
- support for the currently automatically installed Icinga1 checks by Puppet
- support for custom checks
The overview of your nodes in Icinga2 you get at [monitoring.psi.ch](https://monitoring.psi.ch) and there you can handle the alerts and create service windows, etc.

The central infrastructure (automatic provisioning, upstream package synchronisation and Puppet) are stable and production ready.
The configuration management is done with Puppet like for RHEL 7. RHEL7 and RHEL8 hosts can share the same hierarchy in Hiera and thus also the "same" configuration. In cases where the configuration for RHEL7 or RHEL8 differs, the idea is to have both in parallel in Hiera and Puppet shall select the right one.

However please keep in mind that there might be/are still some rough edges and certain packages might be missing (especially PSI internal ones).
If you encounter this please let us know in case of the rough edges and/or the developer of the internal PSI package!
Please still consider also implenting following two migrations when moving to RHEL 8:
- migrate from Icinga1 to [Icinga2](../admin-guide/configuration/icinga2), as Icinga1 will be decommissioned by end of 2024
- explicit [network configuration in Hiera](../admin-guide/configuration/networking) with `networking::setup`, especially if you have static IP addresses or static routes
Bugs and issues can be reported in the [Linux project in JIRA](https://jira.psi.ch/browse/PSILINUX).
