We are a new installation of Hobbit 4.2.0, running on SuSE Linux ES 10 SP1 machines. All has been working fine for a couple of months until yesterday when the CPU load and Users and Processes trend graphs for a particular machine stopped showing data. All other trend graphs for that machine appear to be working correctly. The graphs appear on the Trends page, but the last 16 hours or so show no data for those two graphs.
I'm not familiar with rrd but I do see that the procs.rrd, users.rrd and la.rrd files on the hobbit server have datetime stamps coinciding with the last reported data (about 16 hours ago). The other .rrd files have current datetime stamps. I've tried restarting the hobbit server and the client but that did not fix the problem.
What steps can I take to try to resolve this problem?
Thank you, Mike
I have the exact same problem on a Solaris system talking to Hobbit on Solaris. My conclusion is that I need to reboot the client box to reset the missing information on a who -b and uptime. Because the box is production, it still won't get rebooted for another month. If you do try the system reboot, please let me know either way on whether it worked or not.

Is the CPU status for that host showing a purple status ? If yes, then for some reason the cpu status is not being updated, and this affects the graph updates.
There's also been one report that the hobbitd_rrd module crashed on a specific status message, which could also explain it. In that case, you should have a core file in the ~hobbit/data/tmp/ directory, and some log-entries in hobbitlaunch.cfg.
