  • Article

The C++ Build Insights SDK is compatible with Visual Studio 2017 and later. To see the documentation for these versions, set the Visual Studio Version selector control for this article to Visual Studio 2017 or later. It's found at the top of the table of contents on this page.

The TRACING_SESSION_SYSTEM_EVENT_FLAGS constants are used to describe which system events to collect during a trace. Use them to initialize the TRACING_SESSION_OPTIONS structure's SystemEventFlags field.

Name Events turned on by this flag
TRACING_SESSION_SYSTEM_EVENT_FLAGS_CONTEXT This flag is activated by default by the C++ Build Insights SDK even if not specified explicitly. It enables basic system events that are required by C++ Build Insights to function properly. The events enabled by this flag provide information about processes, threads, and image loading. You can't disable these events.
TRACING_SESSION_SYSTEM_EVENT_FLAGS_CPU_SAMPLES CPU samples
TRACING_SESSION_SYSTEM_EVENT_FLAGS_ALL This flag turns on all system events.
