I suspect that you could extend PCP (the monitoring component of this dashboard) to support Windows' performance counters. The profiling capabilities are certainly there.
PCP can export many hundreds of Windows-specific counters (which it accesses via the PDH APIs). The Windows build does need some love though, as the OP mentioned - its out of date and needs a regular contributor to bring it up to date with the latest PCP sources.
Then Vector should Just Work (tm) for Windows servers too.
