Often times, as part of performance testing, you might be involved in considering various factors such as what ports are getting involved when the traffic communications are being captured by IBM Rational Performance Tester (RPT).
Say, for example...
You need to generate the load from different zones which are classified on your environment network. RPT Work bench will be in Zone-1 and Playback Agents will be in Zone-2. Assuming that there also exists a network firewall between the zones. Because of the high security concerns, before opening the ports for the communication, you are informed to know the communication method and protocols used between RPT Workbench and Load agent machines.
By default, there are a couple of default ports which are specified from RPT perspective such as...
- Work Bench --> License Server - Port 27000 - Bidirectional
- Work Bench -->Playback Agent - Ports 10002, 10003, and 10005 - Incoming
- Playback Agent -->Workbench - Ports 25000, 25001, 25002, 25003, 25004, 25005 - Incoming
So, as an evidence to showcase whether RPT is using the secure / unsecure communication between Workbench machine and Load Agent, you could use a utility such as Wireshark to run the trace for the following use-case.
- The traffic between agents and workbench is HTTP. Run Wireshark in the workbench while an agent is in contact with it.
- While Wireshark is capturing traffic in the workbench, start a schedule and then stop it after say a minute.
- Once schedule is stopped, stop capturing Wireshark and then filter for port 7080. That should give you the complete traffic between the agent and workbench
