Zabbix housekeeper processes more than 90% busy with MaxHousekeeperDelete=1

[bewog]

Hello,

I don't understand what is wrong with housekeeper.

I have plenty mails alerts about Zabbix housekeeper, so i decreased gradually "MaxHousekeeperDelete" option... 5000 then 2500 then 1000 until to 1 (since 2 days) !
I always have this alert on Zabbix Server and also Zabbix Proxy servers.

I'm using Zabbix 5.0.32.

"gate" host are Zabbix Proxy servers :


Zabbix process:


Thank for your help.

If you decrease that value, then less values will be removed by housekeeper...

MaxHousekeeperDelete

No more than 'MaxHousekeeperDelete' rows (corresponding to [tablename], [field], [value]) will be deleted per one task in one housekeeping cycle.

Maybe you should increase this instead?

As explained, a larger value does not solve the problem.

Making it smaller doesn't help. It just gets worse and worse with old data left behind that must be deleted. It will also be necessary to take measures such as tuning the database to improve processing capacity.
