Win32_PerfRawData_PerfNet_Server Class

The Server performance object consists of counters that measure communication between the local computer and the network.
Namespace value is root/CIMV2.
WMI Provider value is WmiPerfInst.


Properties

  • BlockingRequestsRejected
  • The number of times the server has rejected blocking SMBs due to insufficient count of free work items. Indicates whether the MaxWorkItem or MinFreeWorkItems server parameters might need to be adjusted.

  • BytesReceivedPersec
  • The number of bytes the server has received from the network. Indicates how busy the server is.

  • BytesTotalPersec
  • The number of bytes the server has sent to and received from the network. This value provides an overall indication of how busy the server is.

  • BytesTransmittedPersec
  • The number of bytes the server has sent on the network. Indicates how busy the server is.

  • Caption
  • A short textual description (one-line string) for the statistic or metric.

  • ContextBlocksQueuedPersec
  • Context Blocks Queued per second is the rate at which work context blocks had to be placed on the server's FSP queue to await server action.

  • Description
  • A textual description of the statistic or metric.

  • ErrorsAccessPermissions
  • The number of times opens on behalf of clients have failed with STATUS_ACCESS_DENIED. Can indicate whether somebody is randomly attempting to access files in hopes of getting at something that was not properly protected.

  • ErrorsGrantedAccess
  • The number of times accesses to files opened successfully were denied. Can indicate attempts to access files without proper access authorization.

  • ErrorsLogon
  • The number of failed logon attempts to the server. Can indicate whether password guessing programs are being used to crack the security on the server.

  • ErrorsSystem
  • The number of times an internal Server Error was detected. Unexpected errors usually indicate a problem with the Server.

  • FileDirectorySearches
  • The number of searches for files currently active in the server. Indicates current server activity.

  • FilesOpen
  • The number of files currently opened in the server. Indicates current server activity.

  • FilesOpenedTotal
  • The number of successful open attempts performed by the server of behalf of clients. Useful in determining the amount of file I/O, determining overhead for path-based operations, and for determining the effectiveness of open locks.

  • Frequency_Object
  • Not applicable.

  • Frequency_PerfTime
  • Not applicable.

  • Frequency_Sys100NS
  • Not applicable.

  • LogonPersec
  • Logon/sec is the rate of all server logons.

  • LogonTotal
  • Logon Total includes all interactive logons, network logons, service logons, successful logon, and failed logons since the machine is last rebooted.

  • Name
  • The Name property defines the label by which the statistic or metric is known. When subclassed, the property can be overridden to be a Key property.

  • PoolNonpagedBytes
  • The number of bytes of non-pageable computer memory the server is using. This value is useful for determining the values of the MaxNonpagedMemoryUsage value entry in the Windows NT Registry.

  • PoolNonpagedFailures
  • The number of times allocations from nonpaged pool have failed. Indicates that the computer's physical memory is too small.

  • PoolNonpagedPeak
  • The maximum number of bytes of nonpaged pool the server has had in use at any one point. Indicates how much physical memory the computer should have.

  • PoolPagedBytes
  • The number of bytes of pageable computer memory the server is currently using. Can help in determining good values for the MaxPagedMemoryUsage parameter.

  • PoolPagedFailures
  • The number of times allocations from paged pool have failed. Indicates that the computer's physical memory or paging file are too small.

  • PoolPagedPeak
  • The maximum number of bytes of paged pool the server has had allocated. Indicates the proper sizes of the Page File(s) and physical memory.

  • ReconnectedDurableHandles
  • The number of reconnected durable handles, the ratio of "reconnected durable handles"/"total durable handles" indicates how much performance gain from reconnect durable handles.

  • ReconnectedResilientHandles
  • The number of reconnected resilient handles, the ratio of "reconnected resilient handles"/"total resilient handles" indicates how much performance gain from reconnect resilient handles.

  • ServerSessions
  • The number of sessions currently active in the server. Indicates current server activity.

  • SessionsErroredOut
  • The number of sessions that have been closed due to unexpected error conditions or sessions that have reached the autodisconnect timeout and have been disconnected normally.

  • SessionsForcedOff
  • The number of sessions that have been forced to logoff. Can indicate how many sessions were forced to logoff due to logon time constraints.

  • SessionsLoggedOff
  • The number of sessions that have terminated normally. Useful in interpreting the Sessions Times Out and Sessions Errored Out statistics--allows percentage calculations.

  • SessionsTimedOut
  • The number of sessions that have been closed due to their idle time exceeding the AutoDisconnect parameter for the server. Shows whether the AutoDisconnect setting is helping to conserve resources.

  • SMBBranchCacheHashBytesSent
  • The amount of SMB BranchCache hash data sent from the server. This includes bytes transferred for both hash header requests and full hash data requests.

  • SMBBranchCacheHashGenerationRequests
  • The number of SMB BranchCache hash generation requests that were sent by SRV2 to the SMB Hash Generation service because a client requested hashes for the file and there was either no hash content for the file or the existing hashes were out of date.

  • SMBBranchCacheHashHeaderRequests
  • The number of SMB BranchCache hash requests that were for the header only received by the server. This indicates how many requests are being done to validate hashes that are already cached by the client.

  • SMBBranchCacheHashRequestsReceived
  • The number of SMB BranchCache hash requests that were received by the server.

  • SMBBranchCacheHashResponsesSent
  • The number of SMB BranchCache hash responses that have been sent from the server.

  • Timestamp_Object
  • Not applicable.

  • Timestamp_PerfTime
  • Not applicable.

  • Timestamp_Sys100NS
  • Not applicable.

  • TotalDurableHandles
  • The number of durable handles, it indicates how many durable handles keep alive ever when SMB2 sessions are disconnected.

  • TotalResilientHandles
  • The number of resilient handles, it indicates how many resilient handles keep alive ever when SMB2 sessions are disconnected.

  • WorkItemShortages
  • The number of times STATUS_DATA_NOT_ACCEPTED was returned at receive indication time. This occurs when no work item is available or can be allocated to service the incoming request. Indicates whether the InitWorkItems or MaxWorkItems parameters might need to be adjusted.
