The plugin/command you are using to check the host is providing no command line output but is still exiting with a code of 0 (successful). Try running the check_command, as the nagios user, exactly as it's defined, from the command line and then 'echo $?'. The results of the echo for a down host should be '2'. Chances are you're going to see some additional error output from ping/check_ping. There was also a suggestion earlier for another issue to add '2>&1' to the end of the check_command definition to redirect error output back to Nagios. If that works as advertised, and I believe it will, that could be informative as well. -- Marc ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
