External SIP/RTP monitoring for FreePBX and Asterisk with Prometheus, VictoriaMetrics and Grafana

FreePBX Integration
1

Hi,

I’m developing sip-exporter, an open-source eBPF sensor that runs as an external container alongside FreePBX/Asterisk. It does not modify FreePBX or Asterisk configuration.

It exports IPv4/UDP SIP and SDP-correlated RTP/RTCP metrics for Prometheus or VictoriaMetrics, including SER/SEER, response codes, registrations, RTP loss, jitter, PDV, estimated MOS and
fraud signals.

The included Grafana dashboard contains 83 panels across 11 sections. A complete gallery is available in the repository:

The container requires privileged Linux and must see the relevant traffic. If RTP bypasses the PBX host, only SIP metrics will be available.

Feedback about FreePBX deployment topology and useful missing metrics is welcome.

Howdy! Welcome to the forums.

This looks like a fun project – sounds like a lot of data processing e.g. RTP packet analysis.

Curious if you are considering IPv6 in addition to IPv4 ?

Is FreePBX?

Not yet, only if there’s a request for it.
