windows-server-2012-logo1

In this article we’ll describe the SMB 3.0 performance counters that are new in Windows 2012 and are considered a base set of counters when you monitor the resource usage of SMB:

 

SMB Client Shares

 

This counter set displays information about file shares on the server that are being accessed by a client that is using SMB protocol version 2 or higher.

 

  • SMB Server Shares

 

This counter set displays information about the SMB2 file shares on the server.

 

  • SMB Server Sessions

 

This counter set displays information about SMB server sessions that are using SMB protocol version 2 or higher.

 

  • Resume Key Filter

 

Performance counters for the Resume Key Filter.

 

  • SMB Direct Connection

 

This performance counter set consists of counters that measure aspects of connection activity. A computer can have multiple SMB Direct connections. The SMB Direct Connection counter set represents each connection as a pair of IP addresses and ports, where the first IP address and port represent the connection’s local endpoint and the second IP address and port represent the connection’s remote endpoint.

 

  • CSV Cache

 

The following counters can be gathered to monitor aspects of the CSV Cache:

I/O satisfied from cache

o Cache IO Read-Bytes

o Cache IO Read-Bytes/Sec

o Cache Read

o Cache Read/Sec

 

I/O satisfied from disk

o Disk IO Read-Bytes

o Disk IO Read-Bytes/Sec

o Disk Read

o Disk Read/Sec

 

Total I/O

o IO Read-Bytes

o IO Read-Bytes/Sec

o IO Read

o IO Read/Sec

 

The material we discussed in last 5 articles about the Windows 2012 File System should help you tune your Windows 2012 File Server for optimal performance based on your scenario. In the next series of articles we’ll cover optimizing Windows 2012 Active Directory.
