Script for VoIP - lattency, jitter & MOS

[louis-m]

Came across this script for measuring network performance specifically for VoIP.
Its a python script which returns latency, jitter and MOS. It requires rrdtool-python to run.

script usage is: ping.py -c 4 -t 1 -d 8.8.8.8 where c= count t= interval d= destination host

Details on MOS can be found here:

Anybody know how this could be integrated into zabbix eg collect stats every 60s etc

OT: That python script is very simple. It uses ICMP packets to measure jitter and that's not a good idea. Reference: https://kb.paessler.com/en/topic/580...lculate-jitter

This looks like an interesting method. It takes a pcap and generates a score from it.

I found another method to do this with our Cisco estate using ip sla's and a shadow ip sla router and then creating a template for the reading required eg jitter, MOS etc
It's working well although you will need Cisco equipment for it.

Check the tools, which can measure jitter: iperf, owping, ntp, ... and choose the right one for your requirements.
