Is a Nagios Plugin to check Call Quality in SIP VoIP (compatible with checkmk, Zabbix, etc)
sipnagios implements the Nagios plugin API for monitoring and performance data.
sipnagios.c is a modification of the original siprtp.c sample in pjproject distribution. Supposedly, it works on Linux, Windows, and anywhere you can compile pjproject on.
It makes a call, checks all the various resulting values (mos, rtt, pdd, tta, jitter, packet loss, bytes and packets transferred, and so on). It verifies these values are included into acceptable, warning, or critical ranges.
If the call has gone well, sipnagios print performance data for Nagios graphs, and returns 0.
If the call fails, or if its measured values are not inside acceptable ranges, it exits with Nagios conventional WARNING or CRITICAL values.
Zabbix seems not able to gather historical performances data from external checks, but will show last call values in GUI
