Windows Performance Monitor (PerfMon) and ETW (PerfMonitor, PerfView work with ETW) are different. ETW operates at the kernel level and has an audit trail, while PerfMon works with counter objects at a higher level. For example, using ETW, you can analyze the behavior of a service / application even during system startup and shutdown. ETW actually removes from where PerfMon stops.
The tool is reasonable
PerfMonitor provides a mechanism for users to collect a collection of ETW data by acting as an ETW controller. This mainly helps in collecting traces for managed code, while other tools like XPerf do this for unmanaged code.
