Members

The following sections list COR_PRF_MONITOR enumeration members by category. The categories are:

No flags set

Member Description
COR_PRF_MONITOR_NONE No flags are set.

Callback flags

Member Description
COR_PRF_MONITOR_ALL Enables all callback events.
COR_PRF_MONITOR_APPDOMAIN_LOADS Controls the AppDomainCreation* and AppDomainShutdown* callbacks in the ICorProfilerCallback interface.
COR_PRF_MONITOR_ASSEMBLY_LOADS Controls the AssemblyLoad* and AssemblyUnload* callbacks in the ICorProfilerCallback interface.
COR_PRF_MONITOR_CACHE_SEARCHES Controls the JITCachedFunctionSearch* callbacks in the ICorProfilerCallback interface.

The behavior of this flag is changed in .NET Framework version 2.0.
COR_PRF_MONITOR_CCW Controls the COMClassicVTable* callbacks in the ICorProfilerCallback interface.
COR_PRF_MONITOR_CLASS_LOADS Controls the ClassLoad* and ClassUnload* callbacks in the ICorProfilerCallback interface.
COR_PRF_MONITOR_CLR_EXCEPTIONS Controls the ExceptionCLRCatcher* callbacks in the ICorProfilerCallback interface.
COR_PRF_MONITOR_CODE_TRANSITIONS Controls the UnmanagedToManagedTransition and ManagedToUnmanagedTransition callbacks in the ICorProfilerCallback interface
COR_PRF_MONITOR_ENTERLEAVE Controls the FunctionEnter*, FunctionLeave*, and FunctionTailCall*profiling global static functions.
COR_PRF_MONITOR_EXCEPTIONS Controls the ExceptionThrown callback and the ExceptionSearch*, ExceptionOSHandler*, ExceptionUnwind*, and ExceptionCatcher* callbacks in the ICorProfilerCallback interface.

COR_PRF_MONITOR_GC Controls the GarbageCollectionStarted, GarbageCollectionFinished, MovedReferences, MovedReferences2, SurvivingReferences, SurvivingReferences2, ObjectReferences, ObjectsAllocatedByClass, RootReferences, RootReferences2, HandleCreated, HandleDestroyed, and FinalizeableObjectQueued callbacks in the ICorProfilerCallback* interfaces. When COR_PRF_MONITOR_GC is allocated, concurrent garbage collection is turned off.
COR_PRF_MONITOR_JIT_COMPILATION Controls the JITCompilation*, JITFunctionPitched, and JITInlining callbacks in the ICorProfilerCallback interface.
COR_PRF_MONITOR_MODULE_LOADS Controls the ModuleLoad*, ModuleUnload*, and ModuleAttachedToAssembly callbacks in the ICorProfilerCallback interface.
COR_PRF_MONITOR_OBJECT_ALLOCATED Controls the ObjectAllocated callback in the ICorProfilerCallback interface.
COR_PRF_MONITOR_REMOTING Controls the Remoting* callbacks in the ICorProfilerCallback interface.
COR_PRF_MONITOR_REMOTING_ASYNC Controls whether the Remoting* callbacks will monitor asynchronous events.
COR_PRF_MONITOR_REMOTING_COOKIE Controls whether a cookie is passed to the Remoting* callbacks.
COR_PRF_MONITOR_SUSPENDS Controls the RuntimeSuspend*, RuntimeResume*, RuntimeThreadSuspended, and RuntimeThreadResumed callbacks in the ICorProfilerCallback interface.
COR_PRF_MONITOR_THREADS Controls the ThreadCreated, ThreadDestroyed, ThreadAssignedToOSThread, and ThreadNameChanged callbacks in the ICorProfilerCallback and ICorProfilerCallback2 interfaces.

Feature-enabling flags

Member Description
COR_PRF_ENABLE_FRAME_INFO Enables the retrieval of an exact ClassID for a generic function by calling the GetFunctionInfo2 method with a COR_PRF_FRAME_INFO value returned by the FunctionEnter2 callback.
COR_PRF_ENABLE_FUNCTION_ARGS Enables argument tracing using the FunctionEnter2 callback or the FunctionEnter3WithInfo callback and the GetFunctionEnter3Info method.
COR_PRF_ENABLE_FUNCTION_RETVAL Enables tracing of return values by using the FunctionLeave2 callback or the FunctionLeave3WithInfo callback and GetFunctionLeave3Info method.
COR_PRF_ENABLE_INPROC_DEBUGGING Deprecated.

In process debugging is not supported. This flag has no effect.
COR_PRF_ENABLE_JIT_MAPS Deprecated.

Allows the profiler to obtain IL-to-native maps by using GetILToNativeMapping. Starting with .NET Framework 2.0, the runtime always tracks IL-to-native maps; therefore, this flag is always considered to be set.
COR_PRF_ENABLE_OBJECT_ALLOCATED Informs the runtime that the profiler may want object allocation notifications. This flag must be set during initialization. It allows the profiler to subsequently use the COR_PRF_MONITOR_OBJECT_ALLOCATED flag to receive ObjectAllocated callbacks.
COR_PRF_ENABLE_REJIT Enables calls to the RequestReJIT and RequestRevert methods. The profiler must set this flag on startup. If the profiler specifies this flag, it must also specify COR_PRF_DISABLE_ALL_NGEN_IMAGES.
COR_PRF_ENABLE_STACK_SNAPSHOT Enables calls to the DoStackSnapshot method.

Configuration flags

Member Description
COR_PRF_DISABLE_ALL_NGEN_IMAGES Prevents all native images (including profiler-enhanced images) from loading. If this flag and the COR_PRF_USE_PROFILE_IMAGES flag are both specified, COR_PRF_DISABLE_ALL_NGEN_IMAGES is used.
COR_PRF_DISABLE_INLINING Disables all inlining.
COR_PRF_DISABLE_OPTIMIZATIONS Disables all code optimizations.
COR_PRF_DISABLE_TRANSPARENCY_CHECKS_UNDER_FULL_TRUST Disables security transparency checks that are normally done during just-in-time (JIT) compilation and class loading for full-trust assemblies. This can make some instrumentation easier to perform.
COR_PRF_USE_PROFILE_IMAGES Causes the native image search to look for profiler-enhanced images. If no profiler-enhanced image is found for a given assembly, the common language runtime falls back to JIT for that assembly. If this flag and the COR_PRF_DISABLE_ALL_NGEN_IMAGES flag are both specified, COR_PRF_DISABLE_ALL_NGEN_IMAGES is used.

Composite flags

Member Description
COR_PRF_ALL Represents all COR_PRF_MONITOR flag values.
COR_PRF_ALLOWABLE_AFTER_ATTACH Represents all COR_PRF_MONITOR flags that can be set after the profiler is attached to a running app. The syntax section indicates the individual flags that are present in this bitmask.
COR_PRF_MONITOR_ALL Enables all callback events.
COR_PRF_MONITOR_IMMUTABLE Represents all COR_PRF_MONITOR flags that can be set only during initialization. Trying to change any of these flags after initialization returns an HRESULT value that indicates failure.
COR_PRF_REQUIRE_PROFILE_IMAGE Represents all COR_PRF_MONITOR flags that require profile-enhanced images.

Remarks

A COR_PRF_MONITOR value is used with the ICorProfilerInfo::GetEventMask and ICorProfilerInfo::SetEventMask methods to define the event notifications that the common language runtime makes to the profiler.
