<p class="MsoNormal">Hello all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is it meant for the “check_ping” command from the Nagios plugins to
<b>not</b> function when using a host name instead of an IP address? I have a handful of hosts that I’ve setup within Nagios that I want to monitor the ping time (as well as a few other items) on, but since they are dhcp clients, I have the host within Nagios
setup with the hostname on my local network instead of an IP address.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I do a simple check_ping using the hostname (which I have entered as the local FQDN, not just a short name), it returns a “Network Unreachable” error.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Example:<o:p></o:p></p>
<p class="MsoNormal">nagios@nagios:/usr/local/nagios/libexec$ ./check_ping -H dceola.twgi.net -w 400,20% -c 600,50%<o:p></o:p></p>
<p class="MsoNormal">CRITICAL - Network Unreachable (dceola.twgi.net)<o:p></o:p></p>
