Personally I would use check_snmp_process.pl from
http://nagios.manubulon.com/ for that.  You'll need to enable snmp on
your local server if you haven't done so already.  The good thing
about this plugin is it works the same whether it's local or remote
server you want to monitor.

You'll need to think about what's the easiest way you can test for
that.  Probably an snmp query using the standard check_snmp plugin if
you can find a suitable OID to query.

Again, look at http://nagios.manubulon.com/ .  This time it's the
check_snmp_int plugin you need.  This can be a little fiddly to get
working, but usually produces good results.  Use snmp v2 to query the
64-bit counters otherwise you'll find they cycle round too quickly.
Bear in mind this one writes temporary files so if you test as
yourself, go find the files and make sure their writeable by nagios
before you let nagios use them.

For the Cisco devices again look at http://nagios.manubulon.com/ ,
this time the check_snmp_env plugin.

How you monitor temperature of your linux hosts will depend a lot on
what your hardware and operating-system is.  It looks like on my
simple Acer netbook here I can monitor temperature (I guess of the
CPU) by querying the OID LM-SENSORS-MIB::lmTempSensorsValue.1  If you
have Dell OpenManage agent or something similar installed, you might
well find there are other OIDs you can query.

hth,

Jim
