Icinga 1.13.0 released

logo_icingaWhile you may have seen a lot of updates in our 2.x development head, Icinga 1.x is still alive and being patched and bug-fixed. Some smaller features have also been incorporated into 1.13.0 so consider upgrading your existing installation.


Changelog Core, IDOUtils, Classic UI


  • Remove deprecated event_profiling_enabled from icinga.cfg

  • Feature #1867: Recurring Downtimes

Changelog Web


  • Ewoud Kohl van Wijngaarden found a way for an SQL injection in Icinga Web’s API. An authenticated user could inject SQL code via a crafted JSON filter (#7924, CVE-2015-2685)

We recommend to update your installation to 1.13.0 as the features are minimal invasive.

Notable changes and features

  • The log now contains the ip address of a user login failed, or the user just logged in and out (#7357)
  • We implemented a command log that contains any command that is send to the Icinga core by an user – written to a separate log file command-20XX-XX-XX.log (#7893)
  • (Bug) Acknowledgments where sent without a proper sticky declaration. This problem has been fixed and host or service acknowledgments are now sticky by default – what it should and was intended to be. (#5838 #7003) Please review our documentation if you are not sure what sticky means.
  • Grids can now display customvariables. Because customvariables are customised on every installation, this feature is disabled by default. See  doc/grids_and_customvars.md for further information.

Other bugs

  • When using Kerberos authentication in a web server a user could receive all credentials when he had a role that had no credentials set (#7892) In our tests that only happens with Kerberos users.
  • When a user could not be imported during login the database exception was not generated correctly (#8301)
  • Don’t contact more authentication providers than necessary during login. Thanks to Victor Hahn (#8341)
  • Fixed the irritating error during application state reset (#8523) The state was always cleared, but an error popped up for the user.

Icinga conquers Asia – Fossasia in Singapore

CeBIT is still running but we take the time to talk a little bit about Singapore last week. Icinga had the chance to give a keynote at the first day of FOSSASIA and it was really a blast. FOSSASIA happened in Singapore for the first time this year. The conference featured over 100 talks and workshops covering the latest in Free and Open Source Technology projects, including those focussed on the development of Singapore as a smart nation.

On Thursday we gave a workshop at the Hackerspace in Singapore. Built by and for geeks, nerds, inventors, engineers, and entrepreneurs, Hackerspace.SG is the Singapore hacker community’s home, living room and laboratory. There was a nice group of interested people and we played around with our vagrant-setup a tried the latest features in Icinga 2.3. It was really fun!

Our slides are published on SlideShare and listed on our presentation page. Thanks to Hong Phuc Dang, Mario Behling and all the others creating this great conference in Asia. We will be back … if you want!

Icinga Web 2 Beta 3 released

Fasten your seat belts, this is the last beta release before we carry our first release candidate to the launching platform, I promise. Our team of hard working scientists locked up in our laboratory and crafted lots of usability enhancements which will boost your monitoring experience: Forms and configuration dialogs are now easy to use and self-explanatory. Many accessibility features help to find information faster and assist screen readers. Reachability information for hosts and services help to identify dependency problems in your setup and sending custom notifications is now as easy as pie.  Search functionality has been added to the documentation module. And we extended the configuration for LDAP connections now supporting encrypted communication using LDAPS or STARTTLS. Last but not least we fixed a lot of bugs along the way.

Thanks for helping us testing, finding issues and sending us pull request. We’re happy about this pretty cool beta release and we’re on a good way to the first release candidate. For detailed information have a look on our roadmap.

Head over to GitHub for the release tarball. Have a great weekend.

Bugfix release Icinga 2 v2.3.2

Thanks for your kind feedback on the initial v2.3.0 release – we’ve found a few bug reports and already implemented fixes. There’s a regression with the disk plugin check command in 2.3.0 – warning and critical thresholds now require the percent sign explicitly. The documentation has been fixed – make sure to update your configuration accordingly.

icinga2_2.3.1Cluster heartbeat does not disconnect clients on slow bandwidth, process groups are killed on timeouts instead of only the parent process and the String type provides a new method called ‘contains‘.

Update: There was a problem with the fix in #8687 which is why we’re now at v2.3.2.

Upgrade now and enjoy Icinga 2 v2.3.1 v2.3.2!


Please note that this version fixes the default thresholds for the disk check which were inadvertently broken in 2.3.0; if you’re using percent-based custom thresholds you will need to add the ‘%’ sign to your custom attributes.


  • Feature 8659: Implement String#contains
  • Bug 8540: Kill signal sent only to check process, not whole process group
  • Bug 8657: Missing program name in ‘icinga2 –version’
  • Bug 8658: Fix check_disk thresholds: make sure partitions are the last arguments
  • Bug 8672: Api heartbeat message response time problem
  • Bug 8673: Fix check_disk default thresholds and document the change of unit
  • Bug 8679: Config validation fail because of unexpected new-line
  • Bug 8680: Update documentation for DB IDO HA Run-Once
  • Bug 8683: Make sure that the /var/log/icinga2/crash directory exists
  • Bug 8684: Fix formatting for the GDB stacktrace
  • Bug 8687: Crash in Dependency::Stop
  • Bug 8691: Debian packages do not create /var/log/icinga2/crash
