Hi Hector,
At first, I see the orange spinning balls... then after some time, this is
replaced with "undefined". I also noticed that ruby seems to be fairly
stable until I try to load these graphs. Then one ruby script will jumpt to
100+ CPU usage and pretty much stay there. Sometimes, I will get a "Could
not connect..." alert during this time and ruby will return to normal.
Seeing stuff like this when I trace the PID of the ruby script:
rt_sigreturn(0x1a) = 121
--- SIGVTALRM (Virtual timer expired) @ 0 (0) ---
sunstone.log:

I am running sunstone and opennebula on the same box... it does seem to be
ruby related, but I never had a problem until Monday. Prior to that, nothing
had changed on my end. I just came into the office on Monday and discvoered
I could not log in to the older, private cloud and the public cloud was very
slow. Upgrading the public cloud seemed to help (aside from the issues
mentioned above), but I can't upgrade the private cloud just yet and I would
rather identify the source of this problem first.
The CLI is very fast and responsive and other tools such as, VNC console
work fine.
I haven't really been using the self-service portal (although I would like
to in the future), but when I try to start it -I get the following error:
Wed Jul 04 19:43:17 2012 [E]: Error initializing authentication system
Wed Jul 04 19:43:17 2012 [E]: [UserPoolInfo] User couldn't be authenticated,
aborting call.
Thanks again for your help.

Hi,
> monitoring graphs on my hosts and virtual machines no longer appear.
Is there an empty graph in place or is there an error message? If you can
attach sunstone.log and sunstone.error (if not empty) after trying to see
those graphs etc. perhaps I see something...
It's not normal that the dashboard takes 30secs to load. I guess the CLI
is not so slow when issuing a listing command (onehost list, onevm list
etc..) right?
And what is the ruby script consuming 100% exactly? (grep pid from 'ps
aux' or press 'c' during the execution of 'top' to find the full command).
If you have this long-wait problem in two different clouds and ruby is
consuming so much cpu I would think there is an issue with your boxes
configuration related to ruby perhaps. What's the output of 'gem list'?
Are you running sunstone and opennebula on the same box? Have you tried
Self-Service interface? Is it so slow as well?
