Icinga 2 v2.4.4 bugfix release

by | Mar 16, 2016

We’ve come across a faulty patch in 2.4.2 which attempted to fix the retry interval in the first NOT-OK soft state. In the end it turned out to cause troubles inside HA clusters as well as with passive check results. The incorrect patch has been reverted and a proper fix is currently investigated but not included in this stable bugfix release yet.
This release also fixes problems with volatile, flapping and recovery notifications. We’ve tackled a problem with multiple directory levels on Windows in combination with the cluster config sync. Last but not least the ITL provided http and postgres check commands got several new options.
When upgrading a cluster environment please always ensure that your master and/or satellites are updated first and then all clients. While we are trying to ensure that minor versions can co-exist there were changes in 2.4.2 for example that required an update on the master and the clients. Your best bet is to keep the versions the same on all nodes.
One thing we’ve recognised on the community support channels and our bug tracker – Icinga 2 depends on the time being in sync like any other distributed application. If you haven’t done so already please enable ntp and monitor possible time differences using the check_ntp_time check plugin. Such differences may cause issues with check updates and must not harm your monitoring environments.
Updated packages for all distributions should be available soon. We’ve also updated the package repositories to support SLES 11 SP4 and SLES 12 SP1.
