Nagios installations which rely on working external commands should have a check which verifys that external commands are really working. This plugins sends a test command and checks the logfile if that command occurs.

$ check_nagios_external_commands -t 120 -p /usr/local/nagios/var/rw/nagios.cmd \
    -l /usr/local/nagios/var/nagios.log
WARNING - command took 23s|command_write=0.85s command_read=22s
