How to monit mariadb

[Tino Hendricks]

Dear list,

I upgraded one (gentoo) server  from mysql-5.7.24 to mariadb-10.1.37 and since 
then I’m not able to check it's running.

monit 5.25.3 Config is unchanged:
check process mysqld with pidfile /run/mysqld/mysql.pid
        group database
        start program = "/etc/init.d/mysql restart" with timeout 30 seconds
        stop program = "/etc/init.d/mysql stop"
        if failed host localhost port 3306 protocol mysql for 3 times within 5 
cycles then alert
        if cpu > 7% for 2 cycles then alert


Port is open:
~ # netstat -ln | grep 3306
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN

Process is running:
 ~ # ps aux | grep mysql
mysql    11281  1.6  0.1 2610924 456172 ?      Ssl  12:53   9:25 
/usr/sbin/mysqld --defaults-file=/etc/mysql/my.cnf
root     14224  0.0  0.0  11192   968 pts/3    S+   22:37   0:00 grep 
--colour=auto mysql

I am out of ideas and grateful for a little hint.

Thanks

Tino
