Many thanks to VW for sponsoring the Elasticsearch and CA-Proxy & On-Demand Signing features in v2.8.0!
We just released another minor bugfix release for Icinga 2. In addition to providing a number of documentation enhancements version 2.7.2 addresses a few bugs. A list of changes can be found here.
Packages for Icinga 2 v2.7.2 for the officially supported distributions should be available shortly.
Very soon we’ll release Icinga version 2.8 which brings the CA-Proxy to life. With this blogpost I want to show you how to use this feature and why it’s great. (more…)
Flapping detection is a feature many monitoring suites offer. It is mainly used to detect unfortunately chosen thresholds, but can also help in detecting network issues or similar. In most cases two thresholds are used, high and low. If the flapping value, which is the percentage of state changes over a set time, gets higher than the high threshold, it is considered flapping. It will then stay flapping until the value drops below the low threshold.
We’ve come around several issues with Icinga 2 v2.7.0 and fixed them with this new v2.7.1 release. It also contains other bug fixes requested by Icinga partners and their customer support (Livestatus, DB IDO downtimehistory).
There also was an issue with large configuration files being synced in distributed environments. Aside from the bugfix the configuration sync logs now tell you how many bytes will be synced for better debugging low bandwidth issues. Cluster setups could also run into the problem that the “Downtime End” event was not correctly updated in the IDO database history tables. (more…)
Users have reported problems with SSL certificates inside a distributed monitoring setup when they
- updated their Icinga 2 package to 2.7.0 on Windows or
- upgraded their distribution which included an update to OpenSSL 1.1.0.
The Windows package also uses OpenSSL 1.1.0 in v2.7.0. This seems to only affect certificates created in 2015 or older.
