For network analysis I want to have Distributed Switch port statistics in my Graphite installation. I’ve created a script that pulls dvSwitch port statistics from a vCenter server, or directly from an ESXi host and sends them to a Carbon Relay. Ports connected to NSX Logical Switches, which are actually distributed Port Groups, are also included. This allows to create universal dashboards with Grafana for example.
This script is intended to run as cronjob every minute. Port Statistics are provided as counters which can be easily converted to per second values with Graphite functions.
