HP LoadRunner - SAP Portal Monitor

Hello

We want to configure a SAP Portal Monitor in HP LoadRunner, but we don't understand what are the following input parameters to provide to the tool:

➤ Application URL. Enter the URL of the administrator server for the application.

➤ Username. Enter the user name for the server administrator page.

➤ Password. Enter the password for the server administrator page.

What do they mean by "server administrator page"?

We already tried with different Portal URLs (Portal, Nw Administration...) without success.

Thanks,

Jon
