I found the reference on that file:
https://github.com/oVirt/ovirt-dwh/blob/master/docs/Notes-about-single-dwhd
It's only to notice that I veryfied the contents of
dwh_history_timeskeeping table @engine db and the dwhUuid it's consistent with the one
in the 10-setup-uuid.conf file
While ovirt-engine-dwh is running the value DwhCurrentlyRunning is correctly set to
"1" and when I issue
systemctl stop ovirt-engine-dwhd the parameter is set to 0, so the dwhd correctly can talk
with engine db... I suppose.
The DisconnectDwh in the vdc_options table is correctly (?) set to its default value
"0"
