	[DisplayName("Active Threads"): ToInstance Amended, Description("Active Threads is the number of threads currently working on a request from the server client for this CPU.  The system keeps this number as low as possible to minimize unnecessary context switching.  This is an instantaneous count for the CPU, not an average over time."): ToInstance Amended] uint32 ActiveThreads;

The server dynamically adjusts the number of threads to maximize server performance."): ToInstance Amended] uint32 AvailableThreads;
	[DisplayName("Available Work Items"): ToInstance Amended, Description("Every request from a client is represented in the server as a 'work item,' and the server maintains a pool of available work items per CPU to speed processing.  This is the instantaneous number of available work items for this CPU.  A sustained near-zero value indicates the need to increase the MinFreeWorkItems registry value for the Server service.  This value will always be 0 in the Blocking Queue instance."): ToInstance Amended] uint32 AvailableWorkItems;
	[DisplayName("Borrowed Work Items"): ToInstance Amended, Description("Every request from a client is represented in the server as a 'work item,' and the server maintains a pool of available work items per CPU to speed processing.  When a CPU runs out of work items, it borrows a free work item from another CPU.  An increasing value of this running counter might indicate the need to increase the 'MaxWorkItems' or 'MinFreeWorkItems' registry values for the Server service.  This value will always be 0 in the Blocking Queue instance."): ToInstance Amended] uint32 BorrowedWorkItems;

	[DisplayName("Current Clients"): ToInstance Amended, Description("Current Clients is the instantaneous count of the clients being serviced by this CPU.  The server actively balances the client load across all of the CPU's in the system.  This value will always be 0 in the Blocking Queue instance."): ToInstance Amended] uint32 CurrentClients;
	[DisplayName("Queue Length"): ToInstance Amended, Description("Queue Length is the current length of the server work queue for this CPU.  A sustained queue length greater than four might indicate processor congestion.  This is an instantaneous count, not an average over time."): ToInstance Amended] uint32 QueueLength;
	[DisplayName("Read Bytes/sec"): ToInstance Amended, Description("Read Bytes/sec is the rate the server is reading data from files for the clients on this CPU.  This value is a measure of how busy the Server is."): ToInstance Amended] uint64 ReadBytesPersec;
	[DisplayName("Read Operations/sec"): ToInstance Amended, Description("Read Operations/sec is the rate the server is performing file read operations for the clients on this CPU.  This value is a measure of how busy the Server is.  This value will always be 0 in the Blocking Queue instance."): ToInstance Amended] uint64 ReadOperationsPersec;
	[DisplayName("Total Bytes/sec"): ToInstance Amended, Description("Total Bytes/sec is the rate the Server is reading and writing data to and from the files for the clients on this CPU.  This value is a measure of how busy the Server is."): ToInstance Amended] uint64 TotalBytesPersec;
	[DisplayName("Total Operations/sec"): ToInstance Amended, Description("Total Operations/sec is the rate the Server is performing file read and file write operations for the clients on this CPU.

WMI is a huge subject, so therefore it is practically impossible to provide a comprehensive example program that covers anything. However, the book �Network programming in .NET� (Buy at Amazon UK) (Buy at Amazon US) covers a much wider scope of WMI, and explains how to leverage it to access the bounty of information held within this vast, yet simple object model.
