I am new to Dynatrace , working on Oracle and I want to know the below:

What is the mapping of

Dashboards&nbsp; &nbsp;\>\> Metric Key \>\> Metric&nbsp; Event \>\> Alerting Profile \>\> XMatter Integration.

Also, I can see some oracle related events but not the keys. For example:

Metric Key event:&nbsp; com.dynatrace.extension.sql-oracle.dataguard.archiveDestErrStatus  
How can I add this metric key, its not visible.

Is it applicable to Oracle RDS Read Replica or RDS&nbsp; Custom?

Hi,

Is extension configured to a Dataguard Oracle database already?

If yes, you should be able to see that metric.
