I'm getting a message of "TNS:listener does not currently know of SID given in connect descriptor" -- The Oracle DB Monitor Configuration screen does not provide a place to include the SID. How do I provide a SID?

Moreover if you have a service name instead of a SID that is very common with latest Oracle versions, you can use that URL instead:
I hope it will help you.
