I inherited an icinga2 installtion (2.12.1-1) on Debian 10.
It has a service for monitoring mariaDB Galera Cluster and uses some WSREP system variables to monitor health.
After upgrade mariadb to latest 10.5. release, some services like “Galera - send-queue-avg” now fail with
UNKNOWN - got no valid response for SELECT VARIABLE_VALUE FROM information_schema.SESSION_STATUS where VARIABLE_NAME ='WSREP_LOCAL_SEND_QUEUE_AVG'
because for very small values this variable is now represented in exponential notation, e.g. 0.0000345 is now shown as 3.45e-05
Could someone give me an advice on how to fix this issue?
Any help is appreciated
