I added Rendezvous in script, upload in ALM, and Create Performance Test with this script.
In the Edit Test - View Rendezvous screen, I could see the Rendezvous added from the script, and is Enable.
Apply one Policy and save the test.
When I run the test in Test Lab, there is no Rendezvous in View Rendezvous, what's the reason? and the running users seem like without Rendezvous.
Make sure the policy is setup correctly (the release when and timeout interval is setup correctly).
