We have a deployment where all Mobile devices are on a private network with private IP addresses. The application already creates a custom HTTP header that includes the device lat/long.
We are able to extract these values by using some custom "Request attributes" rules.
Is there anyway to them use these values to show location on the map's that are included?
One idea that might help: Have your mobile app lookup the location based on Lat/Long. I'm assumgin there's some lookup function or WebService call which is available to perform this lookup, but Dyantrace does not provide it.
Once your App has the 'location' string, then report that to Dynatrace. Then you could explore extracting that data from an HTTP header (for example) and building a report based on this location data.
The important idea is to have your App do the transformation.
