For example replace:




or: By:



  • Move to PHP 8.0
  • Preparing Debian 11 support

Centreon Collect​

As of version 21.10.0, the components of Centreon Collect (Centreon Broker, Centreon Clib, Centreon Engine and Centreon Connectors) are released simultaneously. They are now grouped under this section.


Release date: February 23, 2022

Centreon Broker​

  • Improved the multiplexing of events, which was a performance bottleneck. The processing speed of queued events should be significantly increased.
  • Some TLS trace logs were logged as errors, flooding the log file.
  • The SQL connections stats have been added to the broker stats available via gRPC.
  • Added the SQL Manager statistics in gRPC and stabilized the stats provider.
  • Added to LUA Stream Connectors' perfdata label parser the compatibility with centreon-plugins new metrics naming convention.
Bug fixes​
  • Fixed a regression due to the central broker's cache generation optimization, which was too thorough and prevented BAM from computing KPIs based on boolean rules
  • The central broker's cache generation loaded too much data and took too much time when BAM was activated.
  • Fixed an issue that could cause segmentation faults in centreon-engine when scheduling external commands
  • Fixed a design issue to avoid trying to access variables of broker's new logger when the logger was stopped. This issue could cause segmentation faults.
  • When a single metric is deleted, the corresponding RRD file is now actually removed.
  • If the SQL stream took too long to initialize its connection, then the Perfdata stream timed out and the whole connection failed. To fix this, the timeout has been increased.
  • In some circumstances, the mysql_ping function, which is used to test if the session is still active, could freeze. To fix this, the calls to mysql_ping have been spaced out, a timeout has been added, and the commit management has been consolidated.
  • Fixed an issue causing BAM Business Activities (best status) to remain in an OK state when the OK KPIs were removed
  • Refactored the BAM Business activities downtimes inheritance mechanism so that they are properly inherited and not duplicated anymore.

After having updated centreon-broker to this version, you may still have unwanted remaining downtimes on your Business Activities. It can happen if a downtime that was inherited from a KPI has been duplicated and if the original downtime ended before the bugfix was installed. In that case, you will have to apply the following procedure.

systemctl stop centengine
sed -i -zE 's/(servicecomment|servicedowntime) \{\nhost_name=_Module_BAM_1\n[^}]*\}\n//g' /var/log/centreon-engine/retention.dat
systemctl start centengine

All the downtimes applied on Business Activities have now been removed.

You must then restart the centengine service on all the other pollers to restore the legitimate inherited downtimes.


Centreon Engine​

  • Flapping now starts only on non-OK states. Based on PR #523
  • Flapping now starts only for services of UP hosts or for hosts with UP parent. Based on PR #524. Fixes Issue #192
  • Provide feedback on gRPC client execution success/failure

Centreon Broker​

  • Queues (in memory and retention files) are now cleared for reversed broker flows without peer retention when the connection is reset. This is a change of behavior back to what it should have always been. It will prevent endless retention files for Centreon-Studio (Centreon-Map).
  • [BETA] Centreon-broker is now able to use OpenSSL instead of GNUTLS and allows forcing TLS/SSL version and cipher suite
  • Broker now only loads the modules that are necessary for its inputs and outputs
  • Old broker log format has been removed

Centreon Gorgone​


Release date: February 17, 2022


  • Added an "audit" module to Gorgone to provide an overview of the system status, package versions, + some Centreon metrics.
  • Added a new "httpserverng" module to allow asynchronous API calls.


  • Fixed an issue that caused Service Discovery scans to fail because the wrong message was caught.
  • Fixed an issue that could make Gorgone crash in pull mode.
  • Fixed uninitialized values in Gorgone that could cause error log messages.
  • Fixed an issue that prevented Gorgone from handling advanced Service Discovery features correctly.
  • Fixed an issue in the module management that could cause crashes.


Release date: December 14, 2021


  • Make Gorgone’s private key readable by centreon-gorgone only
  • Gorgone was too long to restart, which could cause the service to reach the systemctl timeout. The time to stop has been thoroughly decreased.


  • Add IPv6 support
