Listener data is not accurate for websocket samplers

[anu shaji]

For websocket requests, for any kind of listeners like aggregate report or view result in table sent and received data is 'zero' always

I'm able to reproduce this for "Sent bytes". W.r.t. "Received bytes": this is set, but (currently) only the bytes that are sent over the ws connection after it is created, are counted (so the bytes used for connection setup are not counted). Either this would explain why you see 0 for received, or the number of bytes is so low that the Kbytes/sec is rounded to 0.

See attached test plan for my reproduction scenario. Thanks for reporting this issue.

As of version 0.11, received sizes are computed correctly. Number of bytes sent is not yet supported, because it requires JMeter 3.1 (and would make the plugin incompatible with JMeter 3.0).
