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:

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.
