Re: [pox-dev] Getting counter values in POX controller
In OpenFlow, these values are known as statistics. Have you read the relevant sections of the OpenFlow specification and the POX manual? If not, I'd suggest reading the following sections in the POX manual: Statistics Events ofp_stats_request - Requesting statistics from switches Statistics Collector Example -- Murphy On Feb 28, 2015, at 11:25 AM, Sandesh Shrestha sande...@ualberta.ca wrote: Dear All, Could you help me with getting the values of counters from open vswitch into the POX controller ie number of bytes sent per flow or per port.

Hey, A generic method would be: 1. Requesting statistics from a switch (see: https://openflow.stanford.edu/display/ONL/POX+Wiki#POXWiki-ofp_stats_request-Requestingstatisticsfromswitches ) 2. Listening to statistics events (see: https://openflow.stanford.edu/display/ONL/POX+Wiki#POXWiki-StatisticsEvents ) Hope it was helpful.
