Hi Ab
Great, a successful install of 10.3, I'm guessing a few things, but unlike Prognosis 9, a new default install of Prognosis 10 has a lot more collectors disabled. So, check that first - in PROGNOSIS configuration, if you find this, "SET RUN ( B24EPS, N)" then change N to Y and click Start. Then a 'ps -ef | grep irtxncol' to see that it stays running and tail the prognosis/server/configuration/wvlog.txt to see if any remaining errors to address with it.
Then, try start that B24EPS configuration again.
If still no luck, make sure to get assistance from your Support provider and provide them an irfax with your findings from trying this.
