Release 21.10.1 · centreon/centreon-collect

Release date: February 23, 2022

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.

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.
