[sdnog] Network performance measurement tool

[Patrick Okui]

Late response but I agree with Sara.

You can likely convince things like Cacti or Nagios to monitor latency but they’re primarily for monitoring usage (in the case of cacti) or availability in the case of Nagios.

By “usage” I mean for example how much bandwidth are you using right now. How much CPU.

By “availability” I mean for example is router X up or down? Can I download the webpage Y from my web server? etc.

Smokeping as Sara mentioned is designed particularly to see what latency you are getting to certain destinations and how this changes over time. That can give you an idea of jitter. I’ve seen plugins to make cacti produce the same information but they don’t work as well.

In the case that you’re looking at a network with speeds of 1Gbps and above, I also recommend perfsonar (https://www.perfsonar.net). This will monitor and detect (between perfsonar nodes) packet loss less than 1% e.g 0.002% and do scheduled bandwidth tests. Definitely this kind of loss is only significant on larger links that are fibre for example. If you’re interested in this you can see some training materials and videos NSRC did in conjunction with perfsonar at  https://learn.nsrc.org/perfsonar
