ETW consumers, which are the applications or tools that collect and analyze events. These can include built-in Windows tools, such as Event Viewer, as well as third-party applications.
ETW sessions, which are used to manage the collection of events. Sessions can be used to specify which providers to collect events from, as well as the level of detail to collect.
Enabling ETW Tracing
Enabling ETW tracing involves several steps. The first step is to identify the ETW provider you want to collect events from. This can be done using the Windows built-in tool, logman. Once you have identified the provider, you can create an ETW session using logman or another tool. This will specify which provider to collect events from, as well as the level of detail to collect.
Using Logman to Enable ETW Tracing
Logman is a built-in Windows tool that can be used to manage ETW sessions. To use logman to enable ETW tracing, follow these steps:
Open a command prompt as an administrator.
Use the logman command to create a new ETW session. For example: logman create trace mysession -p “Microsoft-Windows-Kernel-Process” -o mysession.etl
This will create a new ETW session called mysession, which collects events from the Microsoft-Windows-Kernel-Process provider.
Use the logman command to start the ETW session. For example: logman start mysession
This will start the ETW session, and events will begin to be collected.

What is ETW Tracing and How Does it Work?
ETW (Event Tracing for Windows) is a powerful logging mechanism that allows developers to track and monitor system events, application behavior, and performance issues in real-time. It provides a comprehensive framework for collecting, storing, and analyzing event data, enabling developers to diagnose and troubleshoot problems more efficiently. ETW tracing involves the use of event providers, which are components that generate events, and event consumers, which are applications that collect and process these events.
The ETW tracing process typically begins with the registration of an event provider, which defines the types of events it will generate. When an event occurs, the provider creates an event object and passes it to the ETW subsystem, which stores the event in a buffer. The event consumer can then retrieve the events from the buffer and process them as needed. ETW tracing supports various modes, including kernel-mode and user-mode tracing, allowing developers to monitor events at different levels of the system. By leveraging ETW tracing, developers can gain valuable insights into system behavior, identify performance bottlenecks, and improve the overall reliability and efficiency of their applications.
