Zabbix database IO spike every 22 o'clock

[Guoyu]

Hi,

We are using Zabbix 1.9.7 and with Oracle 11G as our backend database. Our Zabbix Server and Zabbix Database are on separated servers. We are experiencing a IO spike every 22 o'clock on our database server, is there any background task initialized by Zabbix at 22 o'clock everyday?

The attachments shows the network usage of DB host and the top three SQL in Oracle AWR report between 22 o'clock and 23 o'clock.

Any feedback would be appreciated.



Thanks,
Guoyu

Hi,

Maybe HousekeepingFrequency set to 24 in zabbix_server.conf ?

Hi,

Thanks, but our housekeeping is configured to run every hour.

Check the database: at 22.00 the maintenance window starts within the database.

This is normal and should not be altered, unless you know what you're doing
