Is it the file with. Profile is basically a preset that describes what we want to collect in the trace. There are two types of profiles, built-in and custom. The built-in profiles are like the modes in camera. The most digital camera provides modes such as Macro, Portrait, and Landscape that the camera manufacturer preset optimum shutter speed, aperture, and etc to take good photo based on the situation.
The custom profiles are like the manual mode in camera. You need to know the events and the characteristics of the events. Making custom profiles are not very difficult.
Just as with understanding the concept of camera lenses and shutter are the start of the manual mode shot, a few concepts in ETW would give you enough to start authoring the profile.
The custom profile uses. However, for the beginners, let us start looking at the presets, the built-in profiles. WPRUI conveniently shows the built-in profiles in the start UI within the check-box list whereas wpr -profiles command lists out all built-in profiles.
WPR profile list. The left side is the name of the profiles and the right side is the description of the profiles. A profile can define two verbosity levels, verbose and light.
It is up to the profile author to decide what events are included in verbose and light variants. In WPR, the difference between the light and verbose variants in built-in profiles are usually the addition of stackwalk events and chatty event providers in verbose profile. Whether to log to a file or to memory is a decision we have to make. Many factors can influence the decision. In file mode, events are first collected in the buffer then flushed to the file on the disk sequentially.
In memory mode, the events are written to the circular buffers in memory and only at the last moment it becomes a file through the trace merge phase. Which mode to use is really based on the nature of the events and the potential impact on the system where the recording is captured.
If I need to capture the trace without losing events for a long period of time, with less impact on memory, then I would use the file mode so that I can keep all the events while avoiding the circular wrap problem. Threats include any threat of suicide, violence, or harm to another.

After the Windows 10 Creators update our PC began taking over 6 minutes to boot or reboot.
We've tried a lot of fixes, including the "turn hibernation off" command prompt suggested by another user. Nothing has helped yet. Technical Level : Intermediate Summary Windows performance recorder is a good tool to help us diagnose computer problems. To run WPR you need to:. When you have downloaded and installed it, open an elevated command prompt and type the following.
Choose the one that applies to your situation If you want to reduce the size of the file you can choose "Light" instead of verbose. You can learn how to test your memory.

In reply to 01LionProd's post on September 3, WPRUI vs. They both share the same dll but not all the features can be accessed through UI. If you drive only to near-by groceries and the office via well-known highways you can do that with WPRUI.
However, if your needs are versatile and you want to ride the car for a long time, then you would probably want to choose a high-end car though it is manual. Then BAM! WPR complains. Same error message box shows up. In ETW tracing world, the session name is a steering wheel to the session, directly related to the tracing handle.
Most other application require the user to provide the logger name session name to control the session but WPR gives you the default one unless specified. This is a thoughtful gesture but sometimes, well, a stumbling block. The solution is simple. Of course, you can also solve this by setting another instance name.
