I am using Gatling version 2.2.4, I open a websocket and with debug logging, I see that I am getting data, but the websocket check always fails, timing out. Here is my code to open the websocket and create the check:

.exec(ws("\_a\_wsSession\_survey\_open")  
.open("/a/wsSession/survey/${sessionId}/${participantId}?eid=${sessionId}&eType=session&prv=false&pid=${participantId}&hash=")  
.check(wsAwait.within(40).until(1).regex("(.\*)").saveAs(“wsresponse”))  
)

And in my logs, I see the response:

I was first trying to use the jsonPath check, but when that wasn’t working, I figured I would just capture everything with regex, but this isn’t working, either.

At this point, I’m not sure how to debug this further

Charles,  
I am experiencing the same issue. Were you able to resolve your issue and get the check to work?

Thanks,

Yes, I ended up using jsonPath check instead of regex:

.check(wsAwait.within(600).until(1).jsonPath("$…\*").exists.saveAs(“wsResponse”)))

Thanks Charles,

I was using a JSONPath extraction as well, but I modified my code to match with yours, the only real change was the duration of the timeout.

.exec(Notification.openWebsocket)  
//.exec(ws(“Open Check”).check(wsListen.within(10).until(1).jsonPath("$").saveAs(“openResponse”)))  
.exec(ws(“Open Check”).check(wsAwait.within(600).until(1).jsonPath("$…\*").exists.saveAs(“wsResponse”)))

Upon digging into my logs I found the following,

12:59:58.955 [DEBUG] i.g.h.a.a.w.WsActor - **Websocket ‘gatling.http.webSocket’ open**  
12:59:58.955 [DEBUG] i.n.h.c.h.w.WebSocket08FrameDecoder - Decoding WebSocket Frame opCode=1  
12:59:58.955 [DEBUG] i.n.h.c.h.w.WebSocket08FrameDecoder - Decoding WebSocket Frame length=45  
12:59:58.959 [DEBUG] i.g.h.a.a.w.WsActor - **Received text message on websocket ‘gatling.http.webSocket’:{“type”:“active-subscriptions”,“channels”:[]}**  
12:59:58.960 [DEBUG] i.g.h.a.a.w.WsActor - **Setting check on WebSocket 'gatling.http.webSocket’**  
12:59:58.960 [DEBUG] i.g.h.a.a.w.WsActor - setCheck blocking=true timeout=600 seconds

On Line 1: The socket is reported as open.  
On Lines 2-4: The socket receives its first message from the server.  
On Lines 5-6: The socket sets up the check

The fact that the check is setup **after** the message is received is what is causing my problem. Perhaps under load, there is enough of a delay introduced where the check is created before the message is received. But that’s completely unrealiable. Do you recall if you experienced the same out of order operations?

Thanks,
