The LabVIEW Desktop Execution Trace Toolkit (DETT) is a tool that collects various types of trace data from LabVIEW applications. Refer to the LabVIEW Desktop Execution Trace Toolkit Help and the Opening a Trace Connection topic in the LabVIEW Help for more information about using the DETT.
|Note Tracing VI execution using the DETT can have a performance impact on the execution of code module VIs. To minimize the performance impact, connect the DETT as close as possible to the section of code you want to trace.|
When you enable debugging and tracing in TestStand, TestStand configures each LabVIEW Runtime loaded by TestStand to open a unique TCP port. Refer to the TCP Ports for the LabVIEW Runtimes topic for more information about TCP ports used.
Complete the following steps to trace and capture events for VIs executed using the LabVIEW Runtime in a TestStand application:
|Note The DETT can only connect to the TestStand Sequence Editor or a User Interface after TestStand loads a supported LabVIEW Runtime. Determine the appropriate port for the runtime you want to trace. Refer to the TCP Ports for the LabVIEW Runtimes topic for more information.|
If you have a sequence file that executes VIs in one or more project contexts, you must connect to the specific project context you want to trace from the Application Instance drop-down menu.
