5.2.11 Web Request CPU Breakdown File (WEBWCB)

 
 
 The Web CPU Usage Breakdown (WEBWCB) file is derived from the
 SMF type 120, subtype 9 record, CPU Usage Breakdown section.
 The section is optional, and may only contain data for
 certain web request activity of interest.  There is some
 overhead in collecting the data for this section, so it may
 be populated for select web activity for short periods of
 time that are of particular interest to study in more detail.
 
 When the CPU Usage Breakdown section is populated, it may
 produce 1 to 30 records per web request.  Each time the web
 request calls a web or EJB container, Websphere can capture
 the metrics contained in this file for deeper study into
 where the request is spending its time within the
 application.
 

 The following sections describe the file's organization, list
 data elements maintained, and provide usage hints.
