APM 10.7 SP2.

Resolution

When the Data agingTime expires, the Experience view cards will display "No traffic" or "No data" and the card is unavailable.

The default for the property introscope.apm.data.agingTime is one day.

Experience view cards are shown based on the internal cache we build. This cache is built periodically and maintained.
Cache refresh brings partial maps, or full maps based on the amount of changes Map is encountering. A Full map refresh is obtained when there are significant changes in the map, and partial refresh if there are less changes.

introscope.apm.data.agingTime is used for the following 3 reasons.

Appmap edges/vertices to be aged out ( Meaning from internal cache) at that frequency (24 hours by default) .
After this interval edges/vertices which are not seen in last 24 hours are removed from AppMap UI.

Secondly, this interval is also used for database query returns where data can be obsolete based on what is configured for that parameter.

Thirdly, it is also used for agent to resend the discovery transaction traces at half that interval provided that feature is not disabled from the agent side.
