Using SNMP to monitor remote processes and disk space
snmpget -v 1 -c COMMUNITYSTR hostname OID

what OIDs would I use to get information on all the processes and disk space information that are on a particular host.

where can i find out information on all of this?

thanks

If you dont know much about mibs and OIDs best option to start with is following command
Code:
snmpwalk -v 1 -c public localhost .

mind it output will be huge and messy but u will have everything. For best results redirect output to a file and then look for familiar values.
e.g.
Average load
Code:
snmpwalk -v 1 -c public localhost load
UCD-SNMP-MIB::laLoadFloat.1 = Opaque: Float: 15.886719
UCD-SNMP-MIB::laLoadFloat.2 = Opaque: Float: 15.601562
UCD-SNMP-MIB::laLoadFloat.3 = Opaque: Float: 15.335938

system uptime:
Code:
snmpwalk -v 1 -c public localhost sysuptime
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (1862835767) 215 days, 14:32:37.67

you can compare these values while by cross checking with OS commands.
And Finally
Code:
snmpwalk -v 1 -c public localhost disk

Output was too long so i pasted only few lines. Now you can search for OIDs / MIBs and get what u want.
I call it learning while doing
:P

thanks so much!

is there a way to get the list of processes on a remote host via snmp?

Old 11-30-2010
Here man ..

Code:
snmpwalk -v 1 -c public localhost hrSWRun

For disk usage u might also want to check following:
Code:
snmpwalk -v 1 -c public localhost hrStorage

But as i said before... do snmpwalk to your system.since some enterprise oids may be different.
it takes some time but u will get to it.
