Server Object

The Server performance object consists of counters that measure communication between the local computer and the network.

Bytes Total/sec

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.

Detail Level: Novice
Counter Type: PERF_COUNTER_BULK_COUNT

Bytes Received/sec

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

Detail Level: Advanced
Counter Type: PERF_COUNTER_BULK_COUNT

Bytes Transmitted/sec

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

Detail Level: Advanced
Counter Type: PERF_COUNTER_BULK_COUNT

Sessions Timed Out

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.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Sessions Errored Out

The number of sessions that have been closed due to unexpected error conditions. Indicates how frequently network problems are causing dropped sessions on the server.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Sessions Logged Off

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

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Sessions Forced Off

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

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Errors Logon

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.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Errors Access Permissions

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.

Detail Level: Novice
Counter Type: PERF_COUNTER_RAWCOUNT

Errors Granted Access

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

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Errors System

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

Detail Level: Expert
Counter Type: PERF_COUNTER_RAWCOUNT

Blocking Requests Rejected

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 tuning.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Work Item Shortages

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.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Files Opened Total

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.

Detail Level: Novice
Counter Type: PERF_COUNTER_RAWCOUNT

Files Open

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

Detail Level: Novice
Counter Type: PERF_COUNTER_RAWCOUNT

Server Sessions

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

Detail Level: Novice
Counter Type: PERF_COUNTER_RAWCOUNT

File Directory Searches

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

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Pool Nonpaged Bytes

The number of bytes of non-pageable computer memory the server is currently using. This value is useful for determining good values for the MaxNonpagedMemoryUsage parameter.

Detail Level: Expert
Counter Type: PERF_COUNTER_RAWCOUNT

Pool Nonpaged Failures

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

Detail Level: Wizard
Counter Type: PERF_COUNTER_COUNTER

Pool Nonpaged Peak

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.

Detail Level: Expert
Counter Type: PERF_COUNTER_RAWCOUNT

Pool Paged Bytes

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

Detail Level: Expert
Counter Type: PERF_COUNTER_RAWCOUNT

Pool Paged Failures

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

Detail Level: Wizard
Counter Type: PERF_COUNTER_RAWCOUNT

Pool Paged Peak

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.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Context Blocks Queued/sec

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.

Detail Level: Novice
Counter Type: PERF_COUNTER_COUNTER

Logon/sec

Logon/sec includes the rate of all interactive logons, network logons, service logons, successful logon, and failed logons.

Detail Level: Novice
Counter Type: PERF_COUNTER_COUNTER

Logon Total

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

Detail Level: Novice
Counter Type: PERF_COUNTER_RAWCOUNT
