I am new to Orion and need to monitor disk space utilization on some Linux servers. I have a very rudimentary snmpd.conf file working which shows me the server status and Physical memory, cache, etc. My next step is to monitor the disk space. How do I go about that?
I am using the command "disk /sample 20%" that I added to the conf file but it doesn't seem to work. What am I missing? Attached is a screen shot of "df -k".

My snmpd.conf file has following lines:
rocommunity xxxx xxxxx
syslocation xxxxx
syscontact xxxxxx
disk /dev 20%
Yes, I did restart snmpd several times. Thanks for your help in advance.
