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) ---

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?

Hector,
Thanks for the prompt reply. I am ashamed to admit that browser cache
was the problem in this case. The dashboard still takes about 30
seconds to load, but at least it is loading now. I noticed a few
other minor issues though that I can not track down in my logs. For
example, the monitoring graphs on my hosts and virtual machines no
longer appear.
... any advice?
Part of the reason I didn't catch the browser cache issue earlier is
because I have a second CentOS/KVM cloud running version 3.2.0 and the
dashboard recently stopped loading on it as well. This was not fixed
by clearing my browser cache. Eventually, I get a "Could not
connect..." alert and the page never finishes loading. During this
time, there is a ruby script consuming 100+ percent of CPU resources.
When I kill this script, the cloud is still functional but Sunstone is
no longer running.
The logs all appear normal as far as I can tell and all CLI commnands
work without error. Any suggestions here would be greatly appreciated
as well.
Thanks.

Hello,
can you try to remove browsers cache and see if that fixes it?

Hi everybody,
I recently upgraded my CentOS Open Nebula installation from 3.4 to
3.6 (Lagoon).
Prior to the upgrade, I noticed my Sunstone dashboard was loading
slowly on login (the page would load fine, but it took awhile to
load the graphs, number of hosts, etc). I saw there were some
improvements with the Sunstone dashboard with this upgrade, so I
applied it hoping it would help. Now, my Sunstone dashboard doesn't
load any stats or graphs... I just see those spinning orange dots
and the rest of the Sunstone interface does not work either (I'm
assuming because this information is never gathered).
There are no errors in my logs anywhere that I can find. The only
thing I am noticing is that ruby scripts are consuming a large
amount of CPU resources.
If it helps, I am currently running 13 virtual machines on 9 hosts
and all "one" CLI commands work fine.
Any help would be appreciated.
Thanks.
