Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of the IBM WebSphere Application  *
    *                  Server Liberty for z/OS zosRequestLogging-  *

    * PROBLEM DESCRIPTION: Incorrect request start timestamp       *
    *                      captured in SMF 120 subtype 11 records  *
    *                      when using forwarding servlets.         *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    SMF 120 subtype 11 records show an incorrect request start
    timestamp after having processed servlet requests that forward
    requests to other web applications.  More precisely, the request
    start time is captured when the forwarded application starts
    execution and not when the forwarding sevlet starts execution.
    Therefore, forwarding servlet and associated filter processing
    times are missed.
    
    The issue is noticed only when the zosRequestLogging-1.0 feature
    is enabled without the zosWlm-1.0 feature.
    
    If both the zosRequestLogging-1.0 and zosWlm-1.0 features are
    enabled, the request start time is recorded appropriately.
