Hi
Looking at the code I realized that the date/time retrieved from the host
is cached and not refreshed again until the RHV manager engine is restarted
Please open a bug on that, we should be able to notice that the problem was
fixed
Thanks

[ovirt-users] Re: Host has time-drift of xxx seconds
I just found entries in the db pointing to 11 July (1 month ahead) and I
rebooted the engine.It seems that time-drift is somehow related to all the
issues I have observed after patching from 4.3.9 to 4.3.10:
1. ovirt1 started to slow down - solved by stopping chrony, wiping
/var/lib/chrony/drift and a reboot
2. HE stopped logging in the dwh tables and spamming me with ETL service
stopped ...
I hope I fixed it by using:
https://bugzilla.redhat.com/show_bug.cgi?id=1277591#c5
(note I have typed the link, so it might have a typo)
3. Constantly being spammed about host has been activated - most probably that
one is also 1 month ahead in the DB :)
Not fixed yet.
Best Regards,
Strahil Nikolov
At least the events now show real time.
