I'm trying to use monit to monitor services on my deb 11 server but it doesn't seem to detect mysql as running. Code: check process mysql with pidfile /var/run/mysqld/mysql.pid group database start program = "/usr/sbin/service mysql start" stop program = "/usr/sbin/service mysql stop" if failed host 127.0.0.1 port 3306 then restart if 5 restarts within 5 cycles then timeout That directory shows a pid file that hasn't been touched since Mar 9, in spite of many reboots since: I've done a lot of googling and it seems that it's common that a pid file isn't created by mysql or maria. Per a linux discussion on Serverfault, I added the following to my.cnf: Code: [mysqld] pid-file = /var/run/mysqld/mysqld.pid then restarted the mariadb and monit services. Now when I look at the modified date of the pid file, it shows as today's date. In spite of this, however, I get the same error from monit. Does not exist mysql / execution failed mysql / timeout mysql. What do I need to do to monitor mysql/maria on a deb 11 machine?
