<span style='color:#1F497D'>></span>I would like to be able to display the

what you’re asking for, you’d need to use a combination of the “negate”
plugin (included in nagios-plugins) and adaptive monitoring (<a

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>However,
depending on your network, you may find it better to monitor the routers in a
normal way using loopback IP addresses and monitor the status of ISDN interface
with check_snmp_int.pl from <a href="http://nagios.manubulon.com/snmp_int.html"><span
