All Implemented Interfaces:

ITraceFormatter

public class CSVTraceFormatter
extends AbstractTraceFormatter

CSV trace formatter.

This formatter generates a CSV stream from the data of a trace tree to stdout. The format of the CSV stream is as follows:

  trace id, trace path, threadname, duration, isolated duration
 

The column trace path contains chained ids that represent the trace path. The IDs will be separated by dots. Example: The Id $Session.step1.step2 will be generated for a trace step with id step2 that is a child of step1 and is executed in the context of trace session $Session.
