Hi Sahil
If you had used the Manager Agent in MSMP then it is a SE37 function module. You could look at the code and see what it does. In a nutshell, the Manager agent looks for the Manager entered in the Request Field.
The EUP configuration won't help you there except to default the Manager Id. Check your Access Request to see that the User Id is the manager you have for your configuration.
As far as the Instance Runtime goes, that was a poorly worded sentence on my side. What I am saying is go execute the transaction and look for the runtime details for the Access Request so that you can see what the MSMP path/stage the request went to and if an Agent was identified. Transaction is GRFNMW_DBGMONITOR_WD. Again, search or Google for this transaction and you will find information on it. It is a key transaction to assist in troubleshooting.
Please note if you make changes to the MSMP configuration you will need to create a new access request to test for configuration.
