The configuration at remote server (where NRPE resides) is as follow: command[check_ssh]=/usr/local/nagios/libexec/check_ssh command[check_ping]=/usr/local/nagios/libexec/check_ping!100.0,20%!500.0,60% And then at server where .cfg resides the config is this one: define service{ use generic-service host_name bacula-server service_description SSH check_command check_nrpe!check_ssh notifications_enabled 0 } define service{ use generic-service host_name bacula-server service_description PING check_command check_nrpe!check_ping } The error for check_ping command is this: NRPE: Unable to read output and for check_ssh is this: check_ssh: Could not parse arguments What I'm doing wrong or what I'm not doing? </pre> </blockquote> It's not clear why you're using check_nrpe for these two services... that's probably not what you want to do. Check_ssh and check_ping should be run on the Nagios server itself. And, as another member pointed out, you've got the command line options messed up for both service checks: <blockquote><tt>Usage: check_ping -H <host_address> -w <wrta>,<wpl>% -c <crta>,<cpl>% [-p packets] [-t timeout] [-4|-6]</tt> <tt>Usage: check_ssh [-46] [-t <timeout>] [-r <remote version>] [-p <port>] <host></tt> </blockquote> <pre class="moz-signature" cols="72">-- David Wallis Information Technology Advanced Photon Source Argonne National Laboratory </pre> </body> </html>
