===== Desktop Execution Trace Toolkit =====

The Desktop Execution Trace Toolkit (DETT) can help to identify performance issues.

==== Getting Started ====

  - [[https://www.ni.com/de-de/support/downloads/software-products/download.labview-desktop-execution-trace-toolkit.html#411212|download]] a version, which is [[https://www.ni.com/de-de/support/documentation/compatibility/17/desktop-execution-trace-toolkit--dett--and-labview-compatibility.html|compatible]]
  - allow communication between LabVIEW and DETT via VI Server adding localhost to the machine access list (Tools -> Options -> VI Server)
  - open your LV project and the VI you want to analyse
  - in the DETT, select your project from the **Application Instance** dropdown
  - configure the events you want to trace from the **Capture Settings** menu
  - hit the green start button
  - start your VI / application

==== Tipps ====

  * start with capturing Memory Allocations and Reference Leaks
  * add user defined trace events to follow the program sequence
