Nagios Support Forum

It isn't producing any perfdata so no graph. Try the -h option to see if it has an option to make perfdata. If not you need to modify the script or find a new one.

Perfdata comes after the | char at the end of the plugin output. Is it there if you run the script manually? You may want to post the output.

Did you set the nagios hosts as the trap reciever on the dell host?

It looks like you can get that response from a host running nsclient and check_service isn't in the nsclient config...

Looks like the plugin wants args in some order. This from the short help output I read...
command[check_tcp]=/usr/local/nagios/libexec/check_tcp $ARG1$ -w 10 -c 20

Try adding $ARG1$ to the command.
command[check_tcp]=/usr/local/nagios/libexec/check_tcp -w 10 -c 20 $ARG1$

You need a nagios command. Services run commands, and commands run plugins.

Maybe kill the ncpa service processes and rerun the upgrade.

Use curl or wget to fetch the upgrade check URL.

Probably need to see why ndo3 isn't running, why it isn't responding.
