Asterisk: Monitoring Your E1 or T1 With Nagios
E1 monitoring/T1 monitoring is a need that we have on a daily basis because the client’s business depends on it. Here you have an interesting script in PERL that will allow you to monitor your E1/T1 with Nagios. Passing the name of the port as an argument will allow you to use it even if it is not yet connected to a telco. Using the Nagios Remote Plugin Executor on the Asterisk server you can execute it. Additionally, it will report bad ports to you in order to avoid the guessing process.
