Interface WSSessionManagementStats


  1. public interface WSSessionManagementStats
WebSphere Servlet Session Manager Stats interface. Servlet Session Manager stats are structured as follows in the PMI tree:

<server>
|
|__Servlet Session Manager+
  |
  |__<web_application_1>
  |__<web_application_1>

+ indicates logical group

StatDescriptor is used to locate and access particular Stats in the PMI tree.
Example:

  1. StatDescriptor that represents the Servlet session manager stats logical group: new StatDescriptor (new String[] {WSSessionManagementStats.NAME});
  2. StatDescriptor that represents the Servlet session stats for a given web application <web_application_1>: new StatDescriptor (new String[] {WSSessionManagementStats.NAME, "web_application_1"});

InvalidateCount

  1. static final int InvalidateCount
Total number of sessions that are invalidated (CountStatistic).
See Also:

LifeTime

  1. static final int LifeTime
Average session lifetime in milliseconds - TimeStatistic (time invalidated - time created).
See Also:

ActiveCount

  1. static final int ActiveCount
Total number of sessions that are currently accessed by requests (RangeStatistic).

NoRoomForNewSessionCount

  1. static final int NoRoomForNewSessionCount
The number of times that a request for a new session cannot be handled because the value exceeds the maximum session count (CountStatistic).
See Also:

CacheDiscardCount

  1. static final int CacheDiscardCount

See Also:

ExternalReadTime

  1. static final int ExternalReadTime
The time (in milliseconds) taken in reading the session data from persistent store (TimeStatistic).

ExternalReadSize

  1. static final int ExternalReadSize
The size of the session data read from persistent store (TimeStatistic). Applicable only for (serialized) persistent sessions and similar to externalReadTime.
See Also:

ExternalWriteTime

  1. static final int ExternalWriteTime
The time (in milliseconds) taken in writing the session data from persistent store (AverageStatistic). Applicable only for (serialized) persistent sessions and similar to externalReadTime.
See Also:

ExternalWriteSize

  1. static final int ExternalWriteSize
The size of the session data written to persistent store (AverageStatistic). Applicable only for (serialized) persistent sessions and similar to externalReadTime.
See Also:

AffinityBreakCount

See Also:

TimeSinceLastActivated

  1. static final int TimeSinceLastActivated
The time difference in milliseconds of the previous and current access time stamps (TimeStatistic). Does not include sessions timed out.
See Also:

TimeoutInvalidationCount
