Is "snmp-check" a 3rd party plugin? I don't see any perfdata in the output. What is the output of the following command?

I missed typed that it is the check_snmp command

What's the output of the command @lmiltchev posted?

It returns "SNMP OK - 280427"

In the context of drive checks, "usage" generally refers to the amount of disk space consumed. This number can go up and down but generally remains static. Your scalar constantly increments, the data you're seeking is not ### pages, it's ### pages/day. As I mentioned in my earlier comment, Nagios does not perform that calculation. Likewise you won't find in the built in plugins that when you're checking drive space that there is a "/day" calculation involved, it's simply ### bytes.

This: Your disk has 500MB of data and 500MB of free space
Not This: Your disk has 500MB/day of data and 500MB/day of free space

Do you understand? This is not a problem of getting the data, it's a problem of calculating the returned scalar against some change over a period of time. This has to be done using a custom plugin since state is required. There are exceptions such as monitoring interface traffic, but these included plugins do have state.

I thought you were using a 3rd party plugin that didn't return perfdata as when I tested this command (with check_snmp) against one of our printers, I did get a perfdata in the output (see the text in red, to the right of the pipe):

./check_snmp -H 192.168.x.x -p 161 -o 1.3.6.1.2.1.43.10.2.1.4.1.1 -C public 2c -m SNMPv2-SMI
