Problem: Information Collected via ITT API Is Not Available When Attaching to a Process


If you use ITT API in your source code to collect statistics data, like Frame Analysis or JIT-profiling, by attaching to a process, make sure to set up the following environment variables before starting your target application:

  • INTEL_LIBITTNOTIFY32=<>\bin32\runtime\ittnotify_collector.dll

  • INTEL_LIBITTNOTIFY64=<install-dir>\bin64\runtime\ittnotify_collector.dll


The variables should contain the full path to the library without quotes.
