Method ETW Events
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:
CLR Method Events
CLR Method Marker Events
CLR Method Verbose Events
MethodJittingStarted Event
CLR Method Events
The following table shows the keyword and level. (For more information, see CLR ETW Keywords and Levels.)

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.

MethodID |
win:UInt64 |
Unique identifier of a method. For JIT helper methods, this is set to the start address of the method. |
ModuleID |

ClrInstanceID |
win:UInt16 |
Unique ID for the instance of CLR or CoreCLR. |

CLR Method Marker Events
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.
