[ovirt-users] Large DWH Database, how to empty

[Shirly Radco]

Hi,

We don't update the ovirt-engine-dwhd.conf directly.

You need to add the new file to  /ovirt-engine-dwhd.conf.d/ with the lines
DWH_TABLES_KEEP_SAMPLES=
DWH_TABLES_KEEP_HOURLY=
DWH_TABLES_KEEP_DAILY=0

and set the values for how much time you want the data to be kept.
Keep in mind that the dashboards use the information from the samples and
hourly tables for the last 24 hours.

This file will overwrite the default configurations after you restart
ovirt-engine-dwhd.



Best regards,

Shirly Radco
