Hi, I'm noticing that after upgrading to 4.3.8, sometimes the dashboard is very slow and it takes minutes to display and to let me work, even if I'm not interested at all to the dashboard for the activities I have to do. As a consequence it becomes a bottleneck. On engine I see that during these moments the postmaster process related to ovirt_engine_history database is 100% cpu consuming. Almost every minor update I run vacuum but I don't know if there is something else involved. Is there any bug open with in in 4.3.8?
I am not aware of one. Please open, and attach relevant logs. If possible, also please turn on full query logging on PG and attach its logs. Thanks! Also adding Shirly.
Is there any option to set another page as the landing one when I open web admin portal?
I am not aware of one, but there is a very simple workaround: Keep a bookmark in your browser to wherever you want, and after login just press it. I think it should work after a few seconds, even if the dashboard still didn't finish loading.
I have similar problem on a RHV environment where I have done upgrade form 4.2.7 to 4.2.8 and then 4.3.8 in the same day (eventually I'm going to open a case fir this one). When passing from 4.2.7 to 4.2.8 I chose full vacuum for the engine history database:
Perform full vacuum on the oVirt engine history database ovirt_engine_history@localhost? This operation may take a while depending on this setup health and the configuration of the db vacuum process. See https://www.postgresql.org/docs/9.0/static/sql-vacuum.html (Yes, No) [No]: Yes
while I chose NO during the upgrade from 4.2.8 to 4.3.8 that I've done half an hour later.
