Hello,
this monitor needs to be configured as described in the note:
441269 - Setting up tRFC/qRFC monitoring in the alert monitor
From my experience with this monitor people often forget to deactivate one owner as described in this point in the note:
5. Either copy the SAP owner entry (and its set of customizing entries)
or create your own owner entry. Make sure to move the Active mark
to your owner entry. Only one owner can be marked as 'active'.
Please let me know, where exactly you have difficulties with the configuration of this monitor.
Regards,
Alwina
