Re: [ovirt-users] Large DWH Database, how to empty
Hi,
OK thanks! I saw that after upgrading to 4.0.5 from 4.0.4 the DB
already dropped with around 500MB directly and is now at 2GB smaller.
Does this sounds familiar to you with other settings in 4.0.5 ?
Thanks,
Matt

No. That will corrupt your database.
Are you using the full dwh or the smaller version for the dashboards?
Please set the delete thresholds to save less data and the data older then
the time you set will be deleted.
Add a file to /ovirt-engine-dwhd.conf.d/
update_time_to_keep_records.conf
Add these lines with the new configurations. The numbers represent the hours
to keep the data.
DWH_TABLES_KEEP_SAMPLES=24
DWH_TABLES_KEEP_HOURLY=1440
DWH_TABLES_KEEP_DAILY=43800
These are the configurations for a full dwh.
The smaller version configurations are:
DWH_TABLES_KEEP_SAMPLES=24
DWH_TABLES_KEEP_HOURLY=720
DWH_TABLES_KEEP_DAILY=0
The delete process by default at 3am every day (DWH_DELETE_JOB_HOUR=3)
