Final answer:
The storage duration for Code Level and Performance Data in a managed environment commonly defaults to 90 days, although this can be adjusted depending on the service provider's policies or user requirements.
Step-by-step explanation:
When considering how long Code Level and Performance Data is stored for Services at the Code Level in a managed environment, the duration can vary based on the platform or service provider's policy. It's not a one-size-fits-all answer, but most managed services provide a default retention period which might be any of the options given (30, 60, 90, or 120 days). For many Application Performance Management (APM) tools, a common data retention period is 90 days. However, the specific retention period can often be configured based on the user’s requirements or the service level agreement in place. As of my last knowledge update in January 2022, the specific retention periods for code level and performance data in Dynatrace Managed environments can be configured and customized based on the organization's needs. The default setting may vary depending on the version and configuration. Therefore, to get the most accurate and up-to-date information regarding Code Level and Performance Data retention in Dynatrace Managed environments, I recommend checking the official Dynatrace documentation or contacting Dynatrace support for the latest details.
