Difference In Monitoring System Resources From Performance Center & Controller

You might have monitored system resources from HP Performance Center or HP LoadRunner Controller application. But any time did you have faced any problem while collecting data (like %Processor Time, pages/sec etc for memory etc).
There is difference in adding measurements from Performance Center & from Controller. Have you ever seen that when you add System IP for collecting data from this IP while executing your scenario, but the data is not collected. I have faced this problem. Let me explain my scenario in this case:
In Performance Center:
1. You create a scenario, add scripts to execute in Design tabs and add the monitors in the Monitors tab (you provide the UserID/Password while adding the performance counters to be monitored on the machine).
2. You start the scenario, and the performance data is collected from this machine.

But do you really think it is so simple if you add performance counters for a machine on HP LoadRunner Controller.
Try adding the performance counter in LoadRunner Controller scenario and start the scenario. You will see that the window resources graph doesn't display the data. (it has happened with me) .
This is due to the fact that, while adding the machine under window resources, it doesn't ask for the system UserID/Password and the LoadRunner Controller machine UserID/Password overrides the UserID/Password of the system which is to be monitored.

So in this case, the password of the Controller machine and the Monitor machine should be same. Then only you can monitor the system resources added in the Controller scenario.
