Hi,
I have a Zabbix monitoring setup in a cluster. I switched the application over to the second server. After that, I started getting critical alerts about "Utilization of history syncer processes over 75%" on the proxy servers. Additionally, I see "Utilization of LLD worker processes over 75%" on the central server – and this is happening on both nodes, even on the one that's currently the slave server.
This issue did not occur before switching the servers. Both servers have exactly the same configuration. I'm using Zabbix server version 7.0.8, and I have around 2500 hosts added. The database size is approximately 2 TB.
My Zabbix server configuration looks like this:
My Zabbix proxy configuration looks like this:
Has anyone encountered a similar issue, and what could be the possible cause?
