Information about the Synthetic Screenshots:
Reference screenshots are taken when the monitor is created or edited, and subsequently, every 24 hours from a random monitoring location.
Screenshot retention is based on execution retention. They are considered part of the execution data for the execution when they were taken. The default retention time for screenshots is 35 days, however, it can be less in some Managed Environments depending on their storage settings.
Screenshots are captured at the end of each script event, even those without timings.
Success (expected) screenshots are only taken on the first execution, so if your monitor is always successful and has no screenshots, it is possibly always on a re-run.
You can verify the origin of a screenshot by following these steps:
Navigate to the Synthetic dashboard and click on "Analyze executions."
Select the specific execution you're interested in from the list.
Above the screenshot, you will find a label displaying the date and location, indicating, "Screenshot from <date> in <location>."
Click on this link, and you will be instantly directed to the execution where the screenshot was taken or attempted to be taken. Example:
— Both Dynatrace SaaS and Managed (Public and Private Locations):
Confirm that the executions are not always re-runs. Go to the Synthetic, click on “Analyze executions”, and in the execution time, select different timings and confirm the “Execution type” is standard (and not re-run) for some of the executions.
— Dynatrace SaaS (Private Locations - Stores screenshots in S3):
Ensure that the ActiveGate can access the Amazon S3 service.
The following domains in the firewall configuration must be allowed:
