Scalability Tools - NoEngineAvailable Error

naveenbalanagu — Fri, 19 Jan 2018 19:07:17 GMT

I am trying to run load tests using Scalability tools and configured client and server(s) following the instructions given in the documentation.

When I try to connect to App or start test execution, I am getting the below error.

Starting test towards Uri: wss://devqlikpxy1/perf

12:57:53 Workers:1 Errors:0 Warnings:0 Requests:0 Sessions:0

12:57:55 1-1 Connect failed after 2 attempts. ---> One or more errors occurred. ---> NoEngineAvailable [Fatal]:

Test Execution Finished.

WarningCount: 0

ErrorCount: 1

Finishing writing logs...

In our test environment QlikSense is configured in 4 servers.

DEVQLIKCENTRAL <- Central management, engine, etc

DEVQLIKENG1 <- Engine Server

DEVQLIKSCHED1 <- Scheduler/Engine Server

DEVQLIKPXY1 <- Use this one to connect

More details/troubleshooting I have done is here.

Can any one advice what I have to do to resolve this problem?

Thanks

Hi,

Your screenshot might be cut before it's shown, but it looks like you haven't chosen a Load balancing node?

Thanks for your response Daniel.

There are no load balancing servers I have added in the virtual proxy. Do I have to add one? If so, which server I have to add? Is it engine server or all 4 of them ?

I have added DEVQLIKCENTRAL server node under Load Balancing Nodes and after that it started working. Thanks a lot for your help.

You should add all engines you want traffic to, if only DEVQLIKCENTRAL is added all traffic to this virtual proxy will go to that engine only.
