check_ping is just a wrapper for /bin/ping on your system. It's typically going to just return whatever output that does. In this case, I suspect that /bin/ping is just taking too long to return results, i.e. you've specified too many packets for your timeout value perhaps or devices between you and the destination host are slow to return ICMP results, and check_ping or nagios is timing it out before it's done. You could try lowering the number of packets you send (1 or 2 are typically enough for a host check) or, if you're using nagios-3, increasing the plugin timeout and nagios' master service check timeout (in nagios.cfg) to allow the plugin to wait longer for /bin/ping to finish. You could also try using check_icmp instead of /bin/ping. It doesn't rely on /bin/ping and instead has it's own internal ICMP code. -- Marc ------------------------------------------------------------------------------ Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
