We have implemented Nagios/Icinga and Check_MK with Freeswitch. Both do a good (passive) job, as Robert pointed out.
However we also use ESL to check data from hangup events and you may also scan CDRs for RTP statistics.
We usually store those relevant data into Memcache, which is then queried on demand by a Nagios/Icinga or Check_MK MRPE script.

Best regards
Peter

Hey Robert,

sorry for my late reply. Your messages are flagged as spam here (Google Mail)
Yes, check_mk and nagios are free and open source.
It is more likely a system health monitor (is port 5060 reachable and what is the answer => active checks)
And it's reading from standard unix tools (like ps, free - CPU usage => passive checks)
It saves that data in a history (and builds fancy graphs) and sends me mails / SMS messages when some service is down.

I've attached a screenshot from the webinterface.

So check_mk can't monitor RTP traffic, but you can write your own checks in Python (at least the webview)

Are check_mk / nagios free?

Looks like there is a SIP plugin. Is there a RTP plugin?

Hey Robert,

I'm using check_mk / nagios for external monitoring and iftop and top / htop for on site analysis.

Is Homer the best free option for traffic and system monitoring GUI?

               Or is CACTI better option?
