Hi Jan,
Thank you for the update. Unfortunately I think there is an issue in the
server info or the test for MySQL in the output from that function.
I've cloned the
https://salsa.debian.org/nagios-team/monitoring-plugins.git repository
and built a package with gbp buildpackage --git-ignore-branch on the
'trixie' branch.
Once installed onto the target server running MySQL 8.4 I see the following:
jon@TRIXIESERVER:~$ /usr/lib/nagios/plugins/check_mysql -u REDACTED -p
REDACTED
Uptime: 21151 Threads: 9 Questions: 1855375 Slow queries: 0 Opens:

Threads_connected=2;;;; Threads_running=3;;;; Uptime=21151c;;;;
jon@TRIXIESERVER:~$ /usr/lib/nagios/plugins/check_mysql -u REDACTED -p
REDACTED -S
Not a known sever implementation: 8.4.6
Thanks,
Jon

The check_mysql plugin when checking MySQL's replica status fails for

in favour of 'CHECK REPLICA STATUS'
many thanks for coming up with this. This isses was already addressed
in https://github.com/monitoring-plugins/monitoring-plugins/pull/2068
upstream.
https://github.com/monitoring-plugins/monitoring-plugins/compare/master...maintenance-2.4.0-check_mysql.patch
should fix this for 2.4.0 and I've created
https://salsa.debian.org/nagios-team/monitoring-plugins/-/commit/dd1efc8f1be4d98463c567589a657a0e22fb06d4
to address this issue in trixie. Feedback is welcome, as I don't have
any MySQL 8.4 (with replication) available for testing myself.
Thanks and with kind regards, Jan.
