What WQL queries would you use for monitoring typical Windows bottlenecks? Which would you use to obtain data similar to 'top' or 'netstat'? What interval would you poll at?

Here are a few that I find helpful.

SELECT PercentDiskTime, AvgDiskQueueLength, DiskReadBytesPerSec, DiskWriteBytesPerSec FROM Win32_PerfFormattedData_PerfDisk_PhysicalDisk

SELECT Caption, CommittedBytes, AvailableBytes, PercentCommittedBytesInUse, PagesPerSec, PageFaultsPerSec FROM Win32_PerfFormattedData_PerfOS_Memory

SELECT PercentProcessorTime FROM Win32_PerfFormattedData_PerfOS_Processor

SELECT Caption, WorkingSet, PageFaultsPerSec,IOReadBytesPerSec, IOWriteBytesPerSec, ThreadCount, HandleCount FROM Win32_PerfFormattedData_PerfProc_Process

SELECT Caption, BytesReceivedPerSec, BytesSentPerSec FROM Win32_PerfFormattedData_Tcpip_NetworkInterface
