Is it possible to validate or check who has created/deleted resources apart from the azure resources group Audit log or deployment group?
As per my understanding system will hold an audit log for not more than 3 months.
And what in case someone deletes a resources group.. how to track who has deleted etc.
Appreciate your input/guidance or the best approach to capture such details.




All activities, including de deletion of resource groups, are recorded in the Activity Log. It logs also the caller (username of the user that initiated the operation):
You can setup a continuous export of the Activity Log to for example a storage account or a Log Analytics Workspace. The retention for a Log Analytics Workspace can be set to a maximum of 730 days.
If you route the logs to a storage account you can have unlimited storage retention.
