Abstract: A method and system for tracing components in computer applications is provided in which trace data from components can be logged in real time. A hierarchical control interface 209 is used in which leaf nodes 306-311 represent components 204 being traced. The hierarchical control interface 209 includes means for setting trace levels for components 204 being traced. A non-hierarchical trace system 210 is used for carrying out the trace processing and includes means 320 for storing trace level settings received from the hierarchical control interface 209. The trace system 210 also includes means 322 for receiving a call from a component 204 with trace data; means for checking the trace level settings 321 for the component 204; and means for storing or discarding the trace data accordingly.

Abstract: A method and a system for tracing components 202 in computer applications 203 are provided. A trace point has a unique identifier and a bit pattern. The level of filtering of trace points is carried out by providing filtering means 303, 402 using the bit pattern and including means for carrying out an inclusive test 403 to determine if a trace point is to be logged and means for carrying out an exclusive test 404 to determine if a trace point is not to be logged. The unique identifier references text commentary 701 relating to the trace point which is written into the original source code and catalogued at compilation for retrieval when a trace point is traced. The method and system allow a single trace system to trace data from both native and non-native applications.
