This handler executes a method for a data object and creates a graph from this.

The call of the handler “trace.ashx” has the following structure:

http(s)://[Hostname]/(Webapplication)/trace.ashx?id=[Data-Object path]&method=[Methodenname](&[Parameter]=[Value])*

In the following example, we execute an analysis for the system root of an onion data source with the method “test”:

https://server/projects/preview/trace.ashx?id=onion://data/objects/1&method=test

The result of this handler is a GRAPHML file, which is optimized for visualization in the free software yEd.
