Add new Monitor in APM using OPM

Add new Monitor in APM using OPM

Hello,

I've installed OPM and APM Plugin in the same server. I'm now looking for a way to add a new monitor in APM Plugin.
Indeed, when I connect to OPM and navigate to Apps--> Dashboard: I can see the APM interface. But there is no way to add a new monitor (no "Add Monitor" button).

Could you please tell me how to add a new monitor in APM (as they are more informations in APM counters than in OPM for some applications)?
Note that I'm able to connect to APM using https://APM:PORT and add a new monitor using the interface.
But, I'm wondering whether this is the correct way to do it (which mean bypass OPM interface)

Could you please advice?

Thank you in advance

Regards,
Fabrice
