Hi all,
We do a yum update on our zabbix server 3.2.11 and we encounter some issues with the monitoring, main items were unaccessible (red) up to 2 times a day.
I've do some performance test and change the zabbix and server's config files, please see below.
1) I need to know which zabbix 3.2.11 is compatible with all my patches. I didn't find any bugs with this new release..
zabbix 3.2.11
MariaDB 10.1.33
CentOS Linux release 7.5.1804
2) Could you please explain me why the zabbix housekeeper processes is 100% during hours?
3) Are my parameters in files below correct?
4) How to troubleshoot this issue?
Thanks and best regards
N.
