[ovs-discuss] Open vSwitch Prometheus exporter for the kernel datapath

[Matt Layher]

Hi all!

At DigitalOcean, we make heavy use of Open vSwitch but haven't ever had 
much visibility into what the datapath is actually doing.

To remedy this, we've created and open sourced a Prometheus 
(https://prometheus.io) metrics exporter for OVS: 
https://github.com/digitalocean/openvswitch_exporter

It currently gathers metrics from the kernel datapath using genetlink 
with the "ovs_datapath" family, but we are open to expanding it to 
support more metrics and datapaths as well, assuming it can be done in a 
modular way.

The README file provides a quick overview of what the statistics look 
like, but feel free to file an issue if you run into any trouble.

Thanks for your time, and I hope you find this useful!
