How can I plot a single day from a test 3 months ago with high resolution like 1 hour?
Clearly list the Steps to resolve the issue
You can use the Trending function in the Dynatrace Classic Portal to drill down into hour-level details of response time and availability.
In the Dynatrace Classic Portal, select Performance Tests > test type > Trending, where test type is the Backbone, Last Mile, or Synthetic Mobile link.
The object level data of a test older than last 33 days is not stored in the database, so you can only use the Trending chart to get historical data. Trending chart data is test level data, not object level data, so it is not as detailed as the regular performance chart.
