[hobbit] Trend Graphs Stopped Showing Data

[Mike Livenspargar]

And they're back! It seems that all that is needed to get these two trend graphs working again is 24 hours. In both cases where CPU load and users/processes trend graphs have stopped working they have started working again 24 hours after stopping. The 24-hour periods began at different times of the day * one at about 3 pm local, the other at about 5 am local.
 
There were no reboots or restarts of server or client required in order to get things working again. I can't correlate any tasks scheduled to run on those machines that might have caused the graphs to start working again. 
 
Does this offer any clues that will help us resolve this problem?
 
Thanks again,
Mike

As best I can tell all the possibilities you list below look like they should present no problem to the process.
 
Since everything is working except for the two trend graphs I noted, perhaps it would be best if I follow the data flow for one of those graphs. I assume the data for the CPU Load trend graph is pulled from the [uptime] section of the client data report (I'm looking at what is shown when clicking on the 'Client data available' link at the bottom of the cpu status page). Where in the process can I put in any hooks to verify that the data is moving through as expected?
 
Thanks for all your help, and sorry for my lack of hobbit knowledge.

Have you tried checking to see if there are any quota or disk issues?  If you were able to reboot the machine and get your RRD activity back up while restarting the process did not fix your problem it has to be a problem relating between hobbit and your machine (IO, disk, memory, privileges, something).

All other trend graphs are functioning. As far as I can tell all the data is coming over from the client and it appears to be some issue with getting the data where it needs to go to show up in the trend graphs, but I'm just guessing here. 
 
Are there any thoughts on what I could look at to try to resolve this problem?
 
Thanks again,

Well, the trend graphs are showing data again. The server machine was rebooted but it appears the graphs were showing data prior to the reboot. If I had to guess I'd think that some process running on the client caused the data parsing on the server to go awry and once that process ended things started working again. Is there any hobbit-saved data I can examine that might help me figure this out? 
 
 I'll keep my eye on this to see what happens next.
