Zabbix 4.4.7 with Mariadb 10.3.17

[medharrak]

Hi,
I need to change the max_connections on my.cnf file to see if it will resolve the issue of "Too many processes on Zabbix server" that I start to see after I increased the StartPollers to 100,
But I can't find where to change it , the file on /etc/my.cnf is empty
any idea ?

The following triggers are not triggers with a high number of database connections.

Template OS Linux: Too many processes on {HOST.NAME}

Since it is a trigger that the number of processes running on the OS is large, if the environment has a large number of processes in normal times, adjust the threshold value in the trigger conditional expression.

Thank you for your reply,
I'm monitoring more than 100 hosts, First I start seeing "Zabbix unreachable poller processes more than 75/ busy ", by searching the issue I found some suggestion to increase the number of StartPollers and max_connections, when I changed StartPollers to 100 I start seeing this warning "Too many processes on Zabbix server", and I didn't find max_connections

To monitor 100 hosts, you typically don't need 100 pollers. Also "StartPollers" is different from "StartPollersUnreachable".

My recommendation: change "StartPollers" back to whatever it was set to before (probably 5, maybe slightly larger, but not 100), and then increase StartPollersUnreachable by a small integer amount. If it's set to 1, try using 2 or 3 and see if that's enough to keep up with unreachable hosts.

Finally, try figure out why you have so many unreachable hosts.
