centreon-collect-23.10.4

21.10.3

21.10.3

Release date: September 27, 2022

Centreon Engine

Improvements

• Improved security of the gRPC API by listening on 127.0.0.1 by default

Centreon Broker

Improvements

• Improved security of the gRPC API by listening on 127.0.0.1 by default
• Empty strings are now accepted for parameter values in stream connectors

Bug fixes

• Fixed an issue causing pollers to be displayed as running, and resources to be displayed in Resources Status after stopping centengine
• Fixed an issue that caused the RRD rebuild mechanism to fail
• Fixed an issue that caused BAM Business activities with “Ignore the indicator in the calculation” as planned downtime calculation method to stop ignoring downtimed KPIs when they had overlapping downtimes
• Fixed a bug causing Broker to ignore additional arguments
• [Configuration] Extended the size of the URL, Notes and Action URL fields to avoid truncating long URLs

22.04.1

22.04.1

Release date: August 30, 2022

Centreon Engine

Features

• Enable recheck for Anomaly Detection services

Improvements

• Improve security of the gRPC API by listening on 127.0.0.1 by default

Bug fixes

• Fixed an issue that made the name of the resources disappear from Resources Status when linked to a severity or a category (it came back once centengine was restarted)
• Fixed an issue with the way escaped special characters were managed (eg. \n)

Centreon Broker

Improvements

• Improve security of the gRPC API by listening on 127.0.0.1 by default

Bug fixes

• Fixed Broker compression
• Fixed an issue that caused the RRD rebuild mechanism to fail
• Fixed an issue with BAM Business Activities with “Ignore the indicator in the calculation” as planned downtime calculation method. They stopped ignoring downtimed KPIs when they had overlapping downtimes
• Fixed an issue that made the name of the resources disappear from Resources Status when linked to a severity or a category (it came back once centengine was restarted)
• Broker handles multiple options
• Broker with gRPC configured crashed on start
• Deleting a tag does not remove the link with resources in resources_tags table
• Fixed an issue that caused Broker to crash when a BAM output was configured and the BAM tables did not exist
• Fixed an issue with the way escaped special characters were managed (eg. \n)
• Scheduled downtimes used to be inserted one at a time, which caused performance issues on platforms with a lot of recurrent scheduled downtimes. They are now injected in bulk inserts to reduce database solicitation and avoid performance issues.
• [Configuration] Extended the size of the URL, Notes and Action URL fields to avoid truncating long URLs

21.10.2

21.10.2

Release date: June 15, 2022

Centreon Broker

Improvements

• Improved the way TCP connections are stored by keeping them in an ordered structure. This should avoid rare connection issues experienced by some users

Bug fixes

• Fixed an issue that caused broker to crash when a BAM output was configured and the BAM tables did not exist
• Added a bbdo_version function to the LUA libraries for Stream Connectors developers
• Scheduled downtimes used to be inserted one at a time, which caused performance issues on platforms with a lot of recurrent scheduled downtimes. They are now injected in bulk inserts to reduce demands on the database and avoid performance issues.
• Broker crashed when a logger was disabled/off
• Fixed an issue that could prevent broker from connecting again after the database was stopped to make a LVM snapshot
• Broker crashed when its configuration included a filter that referred to a module that wasn't loaded

Centreon Engine

Improvements

• Removed unnecessary informational log messages regarding Anomaly Detection in the Poller configuration export page

Bug fixes

• Fixed an issue that caused centengine to send duplicate service status messages to broker. This change will reduce network bandwidth consumption, database activity and disk I/O.
• Fixed an issue with the way escaped special characters were managed (eg. \\n)
• Fixed an issue that caused loss of recovery notifications when a downtime end notification was sent before recovery
• Reviewed the way time period exceptions are handled to fix some issues with the way notifications are managed

Centreon Perl & SSH Connectors

Bug fixes

• Fixed an issue that could cause the SSH connector to crash
• Fixed a memory leak issue in the Perl connector

22.04.0

fix(broker/storage): with sql/storage, a non-recognized event is kept…

… and produces retention

21.10.1

21.10.1

Release date: February 23, 2022

Centreon Broker

Improvements

• 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.

21.10.0

Centreon Engine

21.10.0

• 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

21.10.0

• 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
