The plugin worked properly without any errors. Just you need to install several perl files using "YUM or CPAN".
Upon satisfaction of those prerequisites, you're good to go.
Worked Commands:
./check_nwc_health --hostname 10.10.0.1 --community nnv007 --mode cpu-load
./check_nwc_health --hostname 10.10.0.1 --community nnv007 --mode uptime
./check_nwc_health --hostname 10.10.0.1 --community nnv007 --mode memory-usage
./check_nwc_health --hostname 10.10.0.1 --community nnv007 --mode count-routes
./check_nwc_health --hostname 10.10.0.1 --community nnv007 --mode list-routes
nnv007 is my SNMP v2 Community Name.
My "command.cfg" file.
=================================
define command{
command_name check_cisco_nexus
command_line $USER1$/check_nwc_health --hostname $HOSTADDRESS$ --community $ARG1$ --mode $ARG2$
}
=================================
My "cisco.cfg" file.
define service{
use network-service
host_name cisco-nexus-1,cisco-nexus-2
service_description Check CPU Load
check_command check_cisco_nexus!nnv007!cpu-load
}
=================================
You can replace cpu-load with,
memory-usage
uptime
count-routes
check-config
& Many More...

Works like a charm
bysnapon, April 24, 2014
Great plugin! Is there a way to change the uptime to show in a unit larger than minutes? Would be helpful to see it in days, weeks, months, etc.

I’ve tried your plugin for Nagios but I ran into some problems after compiling.
I’m using Nagios XI 2012v1.6 on CentOS 6.3 (x64) --with-nagios-group=nagios --with-perl=/usr/bin/perl
Make
Make install
When I execute the plugin (as root) to a HP Procurve switch I get an error:
