Housekeeper Utilization 100%

[Nalo]

Hello, my housekeeper processor has an utilization of frequently 100%.
How can I improve this process. (I want a utilization of max 50%)

What is frequently? How exactly?

The firing of this standard trigger is familiar to many people.
Apply the usual tricks that have been regularly discussed on the forum.

The Utilization was hourly. I already changed the intervall to 4 hours. But the Utilisation is still the same.
I have already searched in the forum, but I can't found any help.
If a data collector has an high Utilisation, I change the amount of collectors. Is this possile with the housekeeper?

You can schedule housekeeper changing your server configuration HousekeepingFrequency=24 (every day);
You can change expiration of each item in template level (History data (use more resources) and Trends (use less));
You can tune your database changing it's configurations to use more resources;

There is a trigger made right in the Zabbix and therefore it regularly appears and warns about the lack of performance.

Just dozens of identical threads:

https://www.zabbix.com/forum/zabbix-troubleshooting-and-problems/483584-utilization-of-housekeeper-processes-over-75

They all end either by finding additional resources or by facilitating the work of housekeer in the form of switching to partitioning,
tsdb or reducing the amount of data by removing redundant templates.
