Method ETW Events

.NET Framework 4.6 and 4.5

These events collect information that is specific to methods. The payload of these events is required for symbol resolution. In addition, these events provide helpful information such as the number of times a method was called.

All method events have a level of "Informational (4)". All method verbose events have a level of "Verbose (5)".

All method events are raised by the JITKeyword (0x10) keyword or the NGenKeyword (0x20) keyword under the runtime provider, or JitRundownKeyword (0x10) or NGENRundownKeyword (0x20) under the rundown provider.

CLR method events are further subdivided into the following:

The following table shows the keyword and level. (For more information, see CLR ETW Keywords and Levels.)

JitRundownKeyword (0x10) rundown provider

NGENRundownKeyword (0x20) rundown provider

The following table shows the event information.

Event

Event ID

Description

MethodLoad_V1

136

Raised when a method is just-in-time loaded (JIT-loaded) or an NGEN image is loaded. Dynamic and generic methods do not use this version for method loads. JIT helpers never use this version.

MethodUnLoad_V1

137

Raised when a module is unloaded, or an application domain is destroyed. Dynamic methods never use this version for method unloads.

MethodDCStart_V1

137

Enumerates methods during a start rundown.

MethodDCEnd_V1

138

Enumerates methods during an end rundown.

The following table shows the event data.

Field name

Description

MethodID

win:UInt64

Unique identifier of a method. For JIT helper methods, this is set to the start address of the method.

ModuleID

win:UInt64

Identifier of the module to which this method belongs (0 for JIT helpers).

MethodStartAddress

win:UInt64

Start address of the method.

MethodSize

win:UInt32

Size of the method.

MethodToken

win:UInt32

0 for dynamic methods and JIT helpers.

MethodFlags

win:UInt32

0x1: Dynamic method.

0x2: Generic method.

0x4: JIT-compiled code method (otherwise NGEN native image code).

0x8: Helper method.

ClrInstanceID

win:UInt16

Unique ID for the instance of CLR or CoreCLR.

These events are raised only under the rundown provider. They signify the end of method enumeration during a start or end rundown. (That is, they are raised when the NGENRundownKeyword, JitRundownKeyword, LoaderRundownKeyword, or AppDomainResourceManagementRundownKeyword keyword is enabled.)

The following table shows the keyword and level.
