This should be possible with Oracle Database Insights, please refer to the documentation https://www.dynatrace.com/support/help/shortlink/database-insights for all the prerequisites, how to set it up and what metrics are being collected/monitored...etc. For Exadata nodes specific metrics, an ActiveGate Extension will be needed. Please reach out to your Dynatrace Account Manager for more information regarding the Extensions.
I hope this helps.
Hello @saiyantanghosh ,
we are currently developing a Dynatrace extension that will allow you to monitor Oracle Exadata and much more from the Oracle world. It will provide both metrics and alerts in Dynatrace. I believe it will be available shortly also on Dynatrace HUB. If you want to be an early adopter or you want to know more, you can reach me directly at email@example.com .
