It includes all application data as well as network protocol information (such as packet headers)."): ToInstance Amended] uint64 BytesReceivedPersec;
	[DisplayName("Bytes Total/sec"): ToInstance Amended, Description("Bytes Total/sec is the rate the Redirector is processing data bytes.  This includes all application and file data in addition to protocol information such as packet headers."): ToInstance Amended] uint64 BytesTotalPersec;
	[DisplayName("Bytes Transmitted/sec"): ToInstance Amended, Description("Bytes Transmitted/sec is the rate at which bytes are leaving the Redirector to the network.  It includes all application data as well as network protocol information (such as packet headers and the like)."): ToInstance Amended] uint64 BytesTransmittedPersec;
	[DisplayName("Connects Core"): ToInstance Amended, Description("Connects Core counts the number of connections you have to servers running the original MS-Net SMB protocol, including MS-Net itself and Xenix and VAX's."): ToInstance Amended] uint32 ConnectsCore;
	[DisplayName("Connects Lan Manager 2.0"): ToInstance Amended, Description("Connects LAN Manager 2.0 counts connections to LAN Manager 2.0 servers, including LMX servers."): ToInstance Amended] uint32 ConnectsLanManager20;
	[DisplayName("Connects Lan Manager 2.1"): ToInstance Amended, Description("Connects LAN Manager 2.1 counts connections to LAN Manager 2.1 servers, including LMX servers."): ToInstance Amended] uint32 ConnectsLanManager21;
	[DisplayName("Connects Windows NT"): ToInstance Amended, Description("Connects Windows NT counts the connections to Windows 2000 or earlier computers."): ToInstance Amended] uint32 ConnectsWindowsNT;
	[DisplayName("Current Commands"): ToInstance Amended, Description("Current Commands counts the number of requests to the Redirector that are currently queued for service.  If this number is much larger than the number of network adapter cards installed in the computer, then the network(s) and/or the server(s) being accessed are seriously bottlenecked."): ToInstance Amended] uint32 CurrentCommands;
	[DisplayName("File Data Operations/sec"): ToInstance Amended, Description("File Data Operations/sec is the rate at which the Redirector is processing data operations. One operation should include many bytes, since each operation has overhead. The efficiency of this path can be determined by dividing the Bytes/sec by this counter to obtain the average number of bytes transferred per operation."): ToInstance Amended] uint32 FileDataOperationsPersec;
	[DisplayName("File Read Operations/sec"): ToInstance Amended, Description("File Read Operations/sec is the rate at which applications are asking the Redirector for data. Each call to a file system or similar Application Program Interface (API) call counts as one operation."): ToInstance Amended] uint32 FileReadOperationsPersec;
	[DisplayName("File Write Operations/sec"): ToInstance Amended, Description("File Write Operations/sec is the rate at which applications are sending data to the Redirector. Each call to a file system or similar Application Program Interface (API) call counts as one operation."): ToInstance Amended] uint32 FileWriteOperationsPersec;
	[DisplayName("Network Errors/sec"): ToInstance Amended, Description("Network Errors/sec is the rate at which serious unexpected errors are occurring. Such errors generally indicate that the Redirector and one or more Servers are having serious communication difficulties. For example an SMB (Server Manager Block) protocol error is a Network Error. An entry is written to the System Event Log and provide details."): ToInstance Amended] uint32 NetworkErrorsPersec;
	[DisplayName("Packets/sec"): ToInstance Amended, Description("Packets/sec is the rate the Redirector is processing data packets.  One packet includes (hopefully) many bytes.  We say hopefully here because each packet has protocol overhead.  You can determine the efficiency of this path by dividing the Bytes/sec by this counter to determine the average number of bytes transferred/packet.  You can also divide this counter by Operations/sec to determine the average number of packets per operation, another measure of efficiency."): ToInstance Amended] uint64 PacketsPersec;
	[DisplayName("Packets Received/sec"): ToInstance Amended, Description("Packets Received/sec is the rate at which the Redirector is receiving packets (also called SMBs or Server Message Blocks).  Network transmissions are divided into packets.  The average number of bytes received in a packet can be obtained by dividing Bytes Received/sec by this counter.  Some packets received might not contain incoming data (for example an acknowledgment to a write made by the Redirector would count as an incoming packet)."): ToInstance Amended] uint64 PacketsReceivedPersec;
	[DisplayName("Packets Transmitted/sec"): ToInstance Amended, Description("Packets Transmitted/sec is the rate at which the Redirector is sending packets (also called SMBs or Server Message Blocks).  Network transmissions are divided into packets.  The average number of bytes transmitted in a packet can be obtained by dividing Bytes Transmitted/sec by this counter."): ToInstance Amended] uint64 PacketsTransmittedPersec;
	[DisplayName("Read Bytes Cache/sec"): ToInstance Amended, Description("Read Bytes Cache/sec is the rate at which applications are accessing the file system cache by using the Redirector.  Some of these data requests are satisfied by retrieving the data from the cache.  Requests that miss the Cache cause a page fault (see Read Bytes Paging/sec)."): ToInstance Amended] uint64 ReadBytesCachePersec;
	[DisplayName("Read Bytes Network/sec"): ToInstance Amended, Description("Read Bytes Network/sec is the rate at which applications are reading data across the network. This occurs when data sought in the file system cache is not found there and must be retrieved from the network.  Dividing this value by Bytes Received/sec indicates the proportion of application data traveling across the network. (see Bytes Received/sec)."): ToInstance Amended] uint64 ReadBytesNetworkPersec;
	[DisplayName("Read Bytes Non-Paging/sec"): ToInstance Amended, Description("Read Bytes Non-Paging/sec are those bytes read by the Redirector in response to normal file requests by an application when they are redirected to come from another computer.  In addition to file requests, this counter includes other methods of reading across the network such as Named Pipes and Transactions.  This counter does not count network protocol information, just application data."): ToInstance Amended] uint64 ReadBytesNonPagingPersec;
	[DisplayName("Read Bytes Paging/sec"): ToInstance Amended, Description("Read Bytes Paging/sec is the rate at which the Redirector is attempting to read bytes in response to page faults.  Page faults are caused by loading of modules (such as programs and libraries), by a miss in the Cache (see Read Bytes Cache/sec), or by files directly mapped into the address space of applications (a high-performance feature of Windows NT)."): ToInstance Amended] uint64 ReadBytesPagingPersec;
	[DisplayName("Read Operations Random/sec"): ToInstance Amended, Description("Read Operations Random/sec counts the rate at which, on a file-by-file basis, reads are made that are not sequential.  If a read is made using a particular file handle, and then is followed by another read that is not immediately the contiguous next byte, this counter is incremented by one."): ToInstance Amended] uint32 ReadOperationsRandomPersec;
	[DisplayName("Read Packets/sec"): ToInstance Amended, Description("Read Packets/sec is the rate at which read packets are being placed on the network.  Each time a single packet is sent with a request to read data remotely, this counter is incremented by one."): ToInstance Amended] uint32 ReadPacketsPersec;
	[DisplayName("Read Packets Small/sec"): ToInstance Amended, Description("Read Packets Small/sec is the rate at which reads less than one-fourth of the server's negotiated buffer size are made by applications.  Too many of these could indicate a waste of buffers on the server.  This counter is incremented once for each read. It does not count packets."): ToInstance Amended] uint32 ReadPacketsSmallPersec;
	[DisplayName("Reads Denied/sec"): ToInstance Amended, Description("Reads Denied/sec is the rate at which the server is unable to accommodate requests for Raw Reads.  When a read is much larger than the server's negotiated buffer size, the Redirector requests a Raw Read which, if granted, would permit the transfer of the data without lots of protocol overhead on each packet.  To accomplish this the server must lock out other requests, so the request is denied if the server is really busy."): ToInstance Amended] uint32 ReadsDeniedPersec;
	[DisplayName("Reads Large/sec"): ToInstance Amended, Description("Reads Large/sec is the rate at which reads over 2 times the server's negotiated buffer size are made by applications.  Too many of these could place a strain on server resources.  This counter is incremented once for each read. It does not count packets."): ToInstance Amended] uint32 ReadsLargePersec;
	[DisplayName("Server Disconnects"): ToInstance Amended, Description("Server Disconnects counts the number of times a Server has disconnected your Redirector.  See also Server Reconnects."): ToInstance Amended] uint32 ServerDisconnects;
	[DisplayName("Server Reconnects"): ToInstance Amended, Description("Server Reconnects counts the number of times your Redirector has had to reconnect to a server in order to complete a new active request.  You can be disconnected by the Server if you remain inactive for too long.  Locally even if all your remote files are closed, the Redirector will keep your connections intact for (nominally) ten minutes.  Such inactive connections are called Dormant Connections.  Reconnecting is expensive in time."): ToInstance Amended] uint32 ServerReconnects;
	[DisplayName("Server Sessions"): ToInstance Amended, Description("Server Sessions counts the total number of security objects the Redirector has managed.  For example, a logon to a server followed by a network access to the same server will establish one connection, but two sessions."): ToInstance Amended] uint32 ServerSessions;
	[DisplayName("Server Sessions Hung"): ToInstance Amended, Description("Server Sessions Hung counts the number of active sessions that are timed out and unable to proceed due to a lack of response from the remote server."): ToInstance Amended] uint32 ServerSessionsHung;
	[DisplayName("Write Bytes Cache/sec"): ToInstance Amended, Description("Write Bytes Cache/sec is the rate at which applications on your computer are writing to the file system cache by using the Redirector.  The data might not leave your computer immediately; it can be retained in the cache for further modification before being written to the network.  This saves network traffic.  Each write of a byte into the cache is counted here."): ToInstance Amended] uint64 WriteBytesCachePersec;
	[DisplayName("Write Bytes Network/sec"): ToInstance Amended, Description("Write Bytes Network/sec is the rate at which applications are writing data across the network. This occurs when the file system cache is bypassed, such as for Named Pipes or Transactions, or when the cache writes the bytes to disk to make room for other data.  Dividing this counter by Bytes Transmitted/sec will indicate the proportion of application data being to the network (see Transmitted Bytes/sec)."): ToInstance Amended] uint64 WriteBytesNetworkPersec;
	[DisplayName("Write Bytes Non-Paging/sec"): ToInstance Amended, Description("Write Bytes Non-Paging/sec is the rate at which bytes are written by the Redirector in response to normal file outputs by an application when they are redirected to another computer.  In addition to file requests, this count includes other methods of writing across the network, such as Named Pipes and Transactions.  This counter does not count network protocol information, just application data."): ToInstance Amended] uint64 WriteBytesNonPagingPersec;
	[DisplayName("Write Bytes Paging/sec"): ToInstance Amended, Description("Write Bytes Paging/sec is the rate at which the Redirector is attempting to write bytes changed in the pages being used by applications.  The program data changed by modules (such as programs and libraries) that were loaded over the network are 'paged out' when no longer needed.  Other output pages come from the file system cache (see Write Bytes Cache/sec)."): ToInstance Amended] uint64 WriteBytesPagingPersec;
	[DisplayName("Write Operations Random/sec"): ToInstance Amended, Description("Write Operations Random/sec is the rate at which, on a file-by-file basis, writes are made that are not sequential.  If a write is made using a particular file handle, and then is followed by another write that is not immediately the next contiguous byte, this counter is incremented by one."): ToInstance Amended] uint32 WriteOperationsRandomPersec;
	[DisplayName("Write Packets/sec"): ToInstance Amended, Description("Write Packets/sec is the rate at which writes are being sent to the network.  Each time a single packet is sent with a request to write remote data, this counter is incremented by one."): ToInstance Amended] uint32 WritePacketsPersec;

This counter is incremented once for each write: it counts writes, not packets."): ToInstance Amended] uint32 WritePacketsSmallPersec;
	[DisplayName("Writes Denied/sec"): ToInstance Amended, Description("Writes Denied/sec is the rate at which the server is unable to accommodate requests for Raw Writes.  When a write is much larger than the server's negotiated buffer size, the Redirector requests a Raw Write which, if granted, would permit the transfer of the data without lots of protocol overhead on each packet.  To accomplish this the server must lock out other requests, so the request is denied if the server is really busy."): ToInstance Amended] uint32 WritesDeniedPersec;

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.
