- Recording statistics about mounting. For example, when you encounter an issue in which bringing a volume online takes a long time, Volsnap frequently is implicated in the delay. Decent diagnostic information will be helpful in troubleshooting.
- Debugging or diagnosis of snapshot failures, especially in scenarios in which it is difficult to use the debugger.
The new diagnostics consist of a set of new Event Tracing for Windows (ETW) events that are logged to the Operational channel. The operational channel receives low-volume events that describe important events during infrequent large operations, such as volume online, volume offline, and so on.
Finally, Volsnap supports the acquisition and transfer of activity IDs.
For the Operational channel, the following are all the possible events:
This mechanism was specific to the Volume Shadow Copy Service (VSS). Therefore, it required custom tools, such as VSS Reports, to extract the information. Also, it retained only the most recent instance of any given diagnostic message.
Note The legacy method of VSS logging is still used in Windows 10 because the ETW addition does not provide a complete replacement.
