Disk monitor issues

[Peters, Ron]

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
/vmfs/devices         4.8T     0  4.8T   0% /vmfs/devices

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...
