Firstly, I changed ServerTestConfig.yaml file and added the hostname with port. Within the file I even included postgres database information on tableau server. Also, I added name and password for users.
Next, I updated dataretriever.config file.
On running the test with go --t=testplans\InteractVizLoadTest.jmx --d=30 --c=1 statement
Number of error are always >= 1. Attached is the screenshot of error screen.
On installing jconsole it seems that JMX counters are not set properly.
