Disk monitor issues

Thanks. Aside from local storage, the datastores are shared between all the servers involved and are exactly the same. The odd part is that some clients display only local disk and others display all the disk. I have compared the 'client data' text output from one client to the next and there is no difference. All the disk is included in the text being sent to the hobbit server. I just don't understand why the hobbit server would display/process some and not others.
Ron.

Ron, if your volume names have spaces or other "special" characters in them you may need to modify the code to account for them. I am no Linux or regex guru, but here is what I did in the 'hobbitclient-linux.sh' file (located in your hobbit client bin directory):
echo "[df]"
/usr/sbin/vdf | sed -e '/^[^ ][^ ]*$/{
N
s/[ ]*\n[ ]*/ /
s/SAN VM Storage 2/SAN_VM_Storage_2/g
s/SAN VM Storage 3/SAN_VM_Storage_3/g
s/SAN VM Storage 4/SAN_VM_Storage_4/g
s/Poseidon Local Storage/Poseidon_Local_Storage/g
s/SAN VM Storage/SAN_VM_Storage/g
s/SAN Storage 3/SAN_Storage_3/g
s/SAN Storage 2/SAN_Storage_2/g
s/SAN Storage 1/SAN_Storage_1/g
}'

No answer so far so here's another question then. How would I debug the server processing the 'client data'. Really just looking at the 'df' data. I've enabled both 'verbose' and 'debug' switches when starting the server and haven't found any issues. I do see the correct entries in the hobbit.chk file.
Any thoughts on why this data isn't be graphed/displayed on the web page?

I've been making some updates to the monitoring of our vmware ESX servers and wanted to monitor the disk usage of the datastores attached to the servers. So, I modified the hobbitclient-linux.sh file and changed the [df] section from using df to using the vmware command vdf.
Now, the 'client data' link for that host on the hobbit/xymon server displays the correct output:
[df]
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 4.9G 1.7G 3.0G 36% /
/dev/sda1 99M 28M 67M 30% /boot
/dev/sda5 2.0G 364M 1.5G 20% /var/log

However, the actual page displaying the filesystem usage and rrd graph only displays local disk:
Tue Apr 28 14:56:51 PDT 2009 - Filesystems OK
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 4.9G 1.7G 3.0G 36% /
/dev/sda1 99M 28M 67M 30% /boot
/dev/sda5 2.0G 364M 1.5G 20% /var/log
What's also very odd is that I have roughly a dozen of these types of boxes and some of them report the full output on the web page but most don't.
Why would the text data be correct, but the web data be different or a sub-set? All the clients are getting their full data to the server. I haven't seen any errors on the server logs relating to specific clients.
Thoughts?
Thanks again...
