Monitor NAS partition which is mounted under Linux

[Anthony Mendoza]

You will need to get the MIBs for your NAS solution and check to make
sure your NAS product offers SNMP support.  The important thing the MIB
will tell you for your NAS product is what OIDs are important.  Here's
an example that I use:

define command {
    command_name    check-snmp-swap
    command_line    $USER1$/check_snmp -H $HOSTADDRESS$ -w $ARG1$ -c
$ARG2$ -C '$ARG3$' -o .1.3.6.1.4.1.2021.4.4.0 -P 1 -l "Free Swap"
}

Here I use SNMP to check the free swap space on my servers.  The OID is
the value given to check_snmp with the -o argument.  This is dependant
on your configuration.  All other parameters are standard with the
exception of -C which is the community name (think of it like a
password) that you setup on your SNMP enabled device.  The particular
example above I use against Linux servers, but with the format of the
command would be exactly the same as your NAS device. 

I just saw this on NagiosExchange that may help you as well:

If you want to learn more about SNMP in general, I learned about it with
this book:
