When running the enablement script in NNMi it gives you the option to use HTTP or HTTPS when accessing the reporting console from within NNMi.Knowing the difference and having the configuration the same on both NNMi and NPS will ensure proper functionality. Otherwise, you will never be able to launch the reporting GUI because of this mismatch.
You can set this in NNMi by running
drive\Program Files (x86)\HP\HP BTO Software\bin\nnmenableperfspi.ovpl.
You can set this in NPS by running configureWebAccess.ovpl. Ensure that you set the same on both, either both HTTP or both HTTPS. You will see cases where the NNMi administrators can’t access the GUI when he clicks on Actions>Reporting Menu in NNMi, you can check the nnmenableperfspi.log in NNMi and by running configureWebAccess.ovpl on NPS.
