[hobbit] Disk not showing
It's the /dev/sdb1 that's not graphing appropriately.
It is graphing on the occasional /mnt that the system does overnight, but not sdb1.

I just noticed that one of my systems disks isn't showing up in the graph for the disk utilization.
Are there any steps to troubleshoot this?

Which one is missing ? And is it the *graph only* that is missing, or is there a filesystem which isn't included at all in the above df output?
Note that NFS mounts are NOT reported by the client.

Hey everyone Today we switched time servers and my hobbit server and clients went crazy. Rrd graphs where not updating and I was getting some kind of time "error in the logs" I decided to back up the rrd and data directory and and then delete everything.
By doing this the graphs started to show up again. But now I am showing negative time in my unchanged status. For example: Status unchanged in -8 hours, -9 minutes
How can I fix that? And was there another fix besides deleting my rrd and host data? This time it was ok because I was going to have to do that anyways after the rest of my production hosts have been added.
But in the future that would not really be an option.
Thanks Richard
I had a similar issue when running the hobbit server on a VMware instance once. The OS under VMWare doesn't accurately keep time - sometimes the time would shift backwards or forwards. When this happens Hobbit does not record the data, because RRD files are time sensitive in that they will only accept updates within a specific time interval.
As for your problem I suspect that the system time on your server
changed due to the different NTP server. Perhaps it was wrong before and
now it's right, or maybe it was right before and now it's wrong. Either
way the jump in time is what caused the problem. I'm not sure how you
can fix it, short of manually editing the timestamps in the rrd files.
Maybe someone else has a better suggestion :)

To change my status back to normal I disabled everything for a 10 minute time limit. Now my unchanged status shows normal.

Do you have an RRDDISKS or NORRDDISKS setting in hobbitserver.cfg ?
Is there a "disk,snapshot.rrd" file in the ~hobbit/data/rrd/HOSTNAME/ directory ?
Does the graph show up on the "trends" column ?
