Today, we are announcing the release of Icinga 2 v2.16.1 which fixes an issue with some performance data writers. We have received a number of problem reports for v2.16.0 which could be traced back to some rework of the writers we did in that version. These issues can prevent Icinga 2 from working entirely and we are still investigating the exact cause. This release effectively reverts the ElasticsearchWriter, GraphiteWriter, GelfWriter, InfluxdbWriter, Influxdb2Writer, and OpenTsdbWriter features to the state they were in v2.15.3, to bring back the more reliable functionality in the meantime.
Additionally, the documentation now clarifies that the OTLPMetricsWriter for OpenTelemetry is not available on some older Linux distributions (Debian 11, Ubuntu 22.04, Amazon Linux 2) due to dependency version constraints.
As usual, the source code of this new version is available on GitHub, packages are from our package repositories, and new container images will soon be pushed to Docker Hub and the GitHub Container Registry.
