I have about 900 monit hosts reporting to a single M/monit VM running CentOS 7.7. I had to tune out (expand) the network port ranges to handle the simultaneous connections. Now I have to use monit itself
to restart the mmonit service several times a day when this shows up in /var/log/messages. Is there any documentation or guidelines for setting up and tuning the MariaDB 5.5 database server? I have a local database on the VM but I could move the DB to a
more powerful, physical MariaDB 10.3 cluster if needed.
