Hi,
I'm quite new to Hobbit and to this list. I managed to install hobbit on a server and also on a few clients. So far, so good. But now I have problems with just one client: It's data doesn't appear on the webpage. All other clients work well. To study the problem I did a tcpdump on the client and there was data send to the server. All machines run RHEL 4. The hobbitclient.cfg is identical on all machines. Only differences in configuration is that the failing client is also monitored for imaps and some rpc. The status of these is displayed.
Any idea what could cause this problem? Where could I search for more information?
Second question: I want to monitor if a usb drive is mounted. How best to do that? Is there a test/ an extension for this?
Ciao, Andreas
This is usually caused by a difference between the name you have in the hobbit servers bb-hosts file, and the name of the client host that is reported from the "hostname" command.
I'm willing to bet that if you check the "Ghost Clients" report, (http://yourhobbit.com/hobbit-cgi/hobbit-ghosts.sh , or see the hobbitd status) you will find that your client is reporting as a "ghost". To fix that, you should either fix the clients hostname, or alternatively you can stop the hobbit client on that machine, and restart it, using the --hostname option to force it to report as the same name as its entry in the servers bb-hosts file.
As for monitoring the USB drive, probably the easiest way is to add an entry to the hobbit-clients.cfg (on the hobbit server) to force that partition to be checked and trended. Something like:
HOST=yourhost.com DISK /media/usb 90 95
Be sure to put this ABOVE the "DEFAULT" entry, and of course use the proper mount point in place of /media/usb. I use this same method to force the monitoring of a few NFS mounted volumes, which Hobbit by default ignores.

Thanks everybody. Yeah, it was the problem about different names used by client. Solved now. I even remember to have read that portion of the man page before but forgot that. Stupid me!
Charles: Sounds like a good solution, I'll try it.

Sorry, but this does not work for me. If I unmount the drive, status stays green. In the disk details page it just shows the other mounted filesystems.

Your going to need to actually test for a file on that filesystem and alert if the file disappears. You just need to make sure that file always exists when the filesystem is mounted, this way when the alarm goes off you know the filesystem isnt mounted anymore.

Is this server behind the firewall? Can you telnet to hobbit server on port 1984 from this client?

I can telnet to this port. So a firewall seems not to be the problem.

Does it show up in the ghost reports? It's possible that it's not sending updates with the same name defined in bb-hosts.

Is data for that client showing up under the Reports->Ghost Clients menu? That's the first place I'd check since some clients do not use the exact same hostname you chose in bb-hosts for their status messages. If that is the case, you can use the CLIENT: tag in bb-hosts to work around that.
