20.10.0​

October 21, 2020

Known behaviours:

  • If a Central is configured to communicate with a Remote Server using SSH, reloading the configuration will raise the following error in Gorgone's log:

    ERROR - [sshclient] Unsupported action 'ADDIMPORTTASKWITHPARENT'

    This is due to the fact that the data export/import process between those two servers does not call the Remote Server API (the HTTP flow is then not needed anymore).

    The call is now made through Gorgone, as for the files copy action, and requires the communication to use ZMQ.

  • Sending values of date_start, date_end and duration of downtimes higher than 2^31 (Tue Jan 19 04:14:08 CET 2038) could block broker's inserts into the database. They are now limited to 2037-12-31 23:59:59.
  • No recovery notification was sent if service went from CRITICAL to WARNING to OK state and user deactivated WARNING notification

From Community​

20.10.6​

July 15, 2021

Bugfixes​

  • Engine stopped working without logging an error

20.10.2​

January 20, 2021

This version requires Centreon Broker version to be 20.10.3 or higher.

Bugfixes​

Notification macros

The macros in which notification information can be found have been fixed (ie $NOTIFICATION$, $HOSTNOTIFICATION$, $SERVICENOTIFICATION*$)

Enhancements​

Instance updates

There is a minimal delay specified in seconds between two instance updates. By default, its value is 30s. It can be set with the variable instance_heartbeat_interval in the centengine.cfg file.

20.10.1​

December 16, 2020

Bugfixes​

Stalking option

The stalking option works again, it has been fixed. Make sure you are not enabling volatile option at the same time to really get an output stalking.

Macros filters

Macros can be filtered. This was possible before and there was a regression breaking this functionality. So now, we can activate the macros filtering and then we can specify which macros to send to broker.

Notifications

Host/service status field 'Last Notification' was filled when state was HARD even if no notification is configured nor sent.

20.10.0​

October 21, 2020

Known behaviours:

  • If Engine on a Poller or Remote Server is not upgraded to 20.10, configuration files copied from an upgraded Central by Gorgone using ZMQ communication will not be readable by Engine process, resulting to this error in Engine log:

    Error: Parsing of global configuration failed: Can't open file '/etc/centreon-engine/centengine.cfg'

    This is due to stricter rights on those files.

    As always, we strongly recommend to upgrade all components to match the Central server's version.

    However, during an upgrade process, it is possible to manually add the user centreon-engine to the centreon-gorgone group with the following command:

    usermod -a -G centreon-gorgone centreon-engine

Bugfixes​

  • Contains all fixes up to version 20.04.7

Centreon Broker​

20.10.12​

Release date: March 10, 2022

Bug fixes​

  • 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.

20.10.11​

Release date: January 20, 2022

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

20.10.10​

Release date: January 13, 2022

Bug fixes​

  • The central broker's cache generation loaded too much data and took too much time when BAM was activated

  • In case of retention on one side of a tcp connection, the connection could get interrupted because of an issue in the flush() function
  • Database connection error flag was not reset in conflict manager once an error occurred (even after successful connection) and could block the insertion into the database
  • The index_id column of table metrics was cast in int32 instead of int64
  • Resolved conflicts that could appear between hostgroups when connections_count > 1
  • Deleting graph from the WUI did not actually delete RRD files

  • Metaservices used as KPIs did not impact BAs (Centreon BAM)
  • CRITICAL impact applied instead of UNKNOWN for BAs used as KPIs (Centreon BAM)
  • Broker was slow to restart because of suboptimal queries processing downtimes and comment
  • Limit the values of downtimes' start date, end date and duration to fit the database columns' types

20.10.4​

20.10.3​

January 20, 2021

Bugfixes​

Conflict manager and comments

It is possible to lock the database during comments insertion. This new version fixes that.

BAM reporting dimensions computation

If there are retention files, dimensions computation could fail because of conflicts between new block computation and old ones (the ones in the retention). There was also an issue of concurrent access to tables during dimensions computation.

BAM availabilities rebuild

When availabilities are rebuilt, durations can be doubled. This new version fixes this issue.

Enhancements​

Logs

Logs are sent to the database in bulk as we already do for customvariables.

Lua

There is a new API available for the Lua connector. To use it, scripts must declare a global variable broker_api_version=2. From the user's point of view, Stream Connectors should work almost the same. In isolate cases, we could see scripts that do not work with this new API, then you can always work with Broker API version 1, by setting the variable to 1 or by removing this variable declaration in the script. Why should we use the v2 version? Because it is faster, really faster.

TCP connections

If the connection between two peers is flapping, it may be difficult for one to reconnect to the other and this could lead to many CLOSE_WAIT on the acceptor side. This new version fixes this issue.

20.10.2​

December 16, 2020

Known behaviours:

  • If TLS encryption is configured to use private key/certificate couple for IPv4/6 input/output endpoints, both ends must be updated to ensure communication.

  • If you use Centreon MAP with TLS encryption, make sure to update MAP server to version >= 20.10.2.

Bugfixes​

TLS

Credentials were not loaded by the TLS connector anymore. This is fixed with this new version.

Custom variables

They were updated several times in the database. It is fixed now.

Build

GnuTLS requirement now matches compilation version.

BAM

Reporting events were not stored into database because of truncated Business Activities names causing duplicate entry errors.

20.10.1​

November 25, 2020

Bugfixes​

Build

Build on Centos8 fixed.

Retention files

The splitter class is now thread safe and does not need external locks anymore. It is also far less strict and allows some reading and some writing at the same time.

TCP

Writing on a tcp stream could slow down in case of many retention files. The issue was essentially in the flush internal function.

Enhancements​

TCP connections

TCP streams are really faster, especially when Broker has retention files and there are a lot of traffic.

SQL and storage streams

Those streams have several improvements:

  • Events exchanges are much faster, especially when Broker has retention files.
  • Several queries have been changed to insert data in bulk, it is the case for custom variables and metrics.
  • There are cases where those streams could crash that have been also fixed.

Statistics

The thread pool has now its own statistics. For now, we have two informations that are the number of threads it contains and its latency in milliseconds that is the duration we have to wait to see a task executed. We post a task to the thread pool at time T1, it is executed by the thread pool at time T2, the latency is T2 - T1.

Command line argument

It is now possible to set the cbd pool size directly on the command line with the –pool_size X argument or -s X.

20.10.0​

October 21, 2020

Known behaviours:

  • If Broker on a Poller or Remote Server is not upgraded to 20.10 (or with a version prior to 20.04.9), the communication between said Poller or Remote Server and an upgraded Central may not work.

    As always, we strongly recommend to upgrade all components to match the Central server's version.

    However, during an upgrade process, communication can be maintained by making sure Broker's configurations match the following conditions:

    • TLS encryption and compression are either set to Auto or No on Central input,
    • TLS encryption and compression are either set to Auto or No on Poller or Remote Server output.

    If the reversed connection mode (one peer retention) is used, the Broker upgrade is mandatory.

Bugfixes​

  • Contains all fixes up to version 20.04.9

April 28, 2021

Bugfixes​
