These sorts of stats/counters should probably be revealed in the GUI as well as via a RestConf set.

I think there are counters that track the number of PACKET_IN messages that are received, but I'm not sure if we track how to tell if they've been processed. You can use cbench to test the raw performance if you're interested and I think that Luis Gomez (at Brocade) is working to lead a group that is measuring performance if that's what you're looking for.

Otherwise, I can look into the code to figure out if we expose any of the counters that you might be interested in.

Hi Colin,

The request means the packet-in from the openflow switches under the controller, or these switches ask controller to tell them how to send the packets.

Do you know how to do?

Thanks

Can you tell me what you would mean by "request". I'm not sure we're tracking global servicing of REST requests or packet_in messages, but it might be something interesting for us to track.

Hello everyone,

Recently I want to use some information of the controller, but I don't know how to get.

I want to get the number of requests are being processed in a controller, but I cannot find any RESTful API in official website..

If you know how to do it, can you teach me?

Thank you

James
