ADDM Report is not produced if logged in user does not have SYSDBA privilege

Question

Hello -
In SQLDEV 4.0 (Early Adapter), I logged in as user with no SYSDBA privilege granted. But ADVISOR granted and  execute on DBMS_ADDM granted and "select any dictionary" granted, etc.
Then i go to the menu View --> DBA --> Performance --> Automatic Database Diagnostic Monitor
Select ADDM report from the available choices.
Out of 3 menu options: Summary, Findings and ADDM Report, I can see the first two, but I am getting a grey screen for ADDM Report.
^^^^^^^^^^^^^^^^^^^^^
If i do exactly the same but login as SYSDBA, then ADDM Report can be produced and can be seen. So the issue is in the missing grants and privileges.
^^^^^^^^^^^^^^^^^^^^^^
The goal that we are pursuing in our shop is to empower developers to work with ADDM reports by having them login as non-SYSDBA user.
^^^^^^^^^^^^^^^^^^^^^^^^
Please advise what privilege should be granted to get this working for non-SYSDBA login
Thank you,

Thank you, Phil.
This worked for me in my quick test case.
Great help, as DBA group wants to allow NON-privileged users (like Developers and QA) to execute ADDM on demand.
Here is my observation for RAC database with two instances.
I have followed your instructions:
"Performance / Automatic Database Diagnostic Monitor -> Run ADDM"
Then
- Uncheck box "By Creating New Snapshot" (this box was checked by default)
- Provide new "Task Name" (let's say "vr1")
- Select "Start Snapshot" (this is where my first confusion is: each screen shot # is shown twice, may be because i have two instances of RAC)
- Select "End Snapshot" (the same way: each SNAP_ID is shown twice)
- and finally APPLY button is pressed
This creates 3 reports:
vr1
vr1$1 (for instance_id=1)
vr1$2 (for instance_id=2_
So, my question is: this expected and normal behavior of the tool?
What if my RAC database has 8 instances? Then I would generate 9 separate ADDM reports?
Is this correct observation?
Thank you,
