Using Icinga2 and like to get your existing performance data into Prometheus? Than try out our new icinga2-exporter. It integrates with Icinga2 over the Icinga2 API and support labeling based on host custom variables. You can use the exporter together with monitor-promdiscovery to have dynamic discovery for the hosts in Icinga2 that should be scrapped.
This is the first release so please send feedback or create issues on the Github site.
