Recursive alerts of “Utilization of housekeeper processes over 75%"

[Barneppe]

Good morning,

I would need your help to better optimize my Zabbix infrastructure. it has been many days that the system has been showing the recursive alert of “ Utilization of housekeeper processes over 75%”.

The instance consists of three machines in HA cluster:
* Zabbix primary server - active (vCPU: 16 / 64 GB RAM).
* Zabbix secondary server - standby (vCPU: 16 / 64 GB RAM)
* MySQL database (vCPU: 16 / 64 GB RAM).

These are the items and alerts configured on the infrastructure:
* Number of hosts: 11406
* Number of items: 241908
* Number of triggers: 495302
* Required server performance, new values per second: 3048.52

Regarding the tuning of the MySQL 8.0 database, the innodb_dedicated_server parameter has been added in the “my.cnf” file so that the system independently configures some values of the innodb.

This is the graph of the internal processes:


Could you please help me?

Thank you in advance for the support.
