#define PSI_FLAG_AUTO_SEQNUM (1 << 10) |
Automatic sequence number flag.
Generate thread instances names automatically.
#define PSI_FLAG_DISABLED (1 << 13) |
Instrument is disabled by default.
#define PSI_FLAG_MEM_COLLECT (1 << 12) |
Enable collecting the memory consumed by threads.
#define PSI_FLAG_MUTABLE (1 << 1) |
Mutable flag.
This flag indicate that an instrumentation point is a general placeholder, that can mutate into a more specific instrumentation point.
#define PSI_FLAG_NO_SEQNUM (1 << 11) |
No sequence number flag.
Use thread instances names without sequence numbers.
#define PSI_FLAG_ONLY_GLOBAL_STAT (1 << 7) |

This flag indicate that an instrumentation point is a singleton.
#define PSI_FLAG_STAGE_PROGRESS (1 << 3) |
Stage progress flag.
This flag apply to the stage instruments only. It indicates the instrumentation provides progress data.
#define PSI_FLAG_THREAD (1 << 2) |
Per Thread flag.
This flag indicates the instrumented object is per thread. Reserved for future use.
#define PSI_FLAG_THREAD_SYSTEM (1 << 9) |

#define PSI_FLAG_UNTIMED (1 << 14) |
Instrument is not timed by default.
#define PSI_FLAG_USER (1 << 6) |
User flag.
This flag indicate that an instrumented object exists on a user or foreground thread. If not set, then the object exists on a system or background thread.
