What action needs to be taken to regain access to the last 30 days of data after a Dynatrace SaaS license expiration?

To regain access to the last 30 days of data after a Dynatrace SaaS license expiration, extending the contract with Dynatrace is the necessary action. When the license expires, access to the platform is typically restricted, which includes the data retention from the last 30 days. By renewing or extending the contract, you ensure that access is reestablished, allowing you to view and analyze this data. This process is critical for maintaining continuous access to insights that are essential for monitoring performance and troubleshooting any issues within your applications.

Other options, such as waiting for 30 days or restarting the service, do not provide a viable solution for accessing the historical data. Similarly, contacting customer support might be necessary for clarifications or assistance, but it won’t directly restore access to the expired data without the action of extending the contract.
