CLR ETW Events

.NET Framework 4.5

.NET Framework 4

The topics in this section describe event tracing for Windows (ETW) events. Each event has an associated keyword and level, which are described in the CLR ETW Keywords and Levels topic. The CLR has two providers for the events:

The runtime provider, which raises events depending on which keywords (categories of events) are enabled. The CLR runtime provider GUID is e13c0d23-ccbc-4e12-931b-d9cc2eee27e4.
The rundown provider, which has special-purpose uses. The CLR rundown provider GUID is a669021c-c450-4609-a035-5af59af4df18.

For more information about the providers, see CLR ETW Providers.
