APAR status

  • Closed as program error.

Error description

  • The event log processing is being enabled for all the event
    logs found on the system.  This is causing high CPU for event
    logs that have high event traffic and no situation is started
    to monitor these logs.  The agent should not enabled the event
    log monitor unless a situation is started that requires the log
    to be monitored.
    
    Detailed Recreation Procedure: Start any situation that monitors
    one log and then all logs will be enabled as can be seen in the
    trace log.
    
    Related Files and Output: None.

Problem summary

  • Situations created to monitor the Windows event logs may cause a
    high CPU condition, because the situation does not define which
    Windows event log to monitor. When a situation does not define
    which Windows event log to monitor, then all the Windows event
    logs must be monitored for events for situation evaluation. Moni
    toring of all the event logs causes a high CPU condition
    because of the high number of events that must be processed for
    all the events logs. Currently, two situations
    NT_Invalid_Logon_Attempt and NT_Service_Error, are shipped with
    the Monitoring Agent for Windows OS and are enabled at start
    up. Both these situations can cause a high CPU condition because
    they do not specify which Windows event log to monitor. To
    correct this problem, the Windows event monitoring process is
    modified to only monitor the Windows event log that is specified
    in the situation. Therefore, it is recommended that any event
    log situation, including the two situations shipped with the Mon
    itoring Agent for Windows OS should specify which Windows event
    log to monitor.
