5.4.10 Report Class Response Time (WLM_EM)

The Report Class Response Time File quantifies transaction
response time by optional report class.  This is a parallel
file containing a subset of the same data elements as the
Service Class Response Time File (WLMSEM).  Measurements in
this file include transaction counts and processing rates,
average elapsed times and standard deviations, and for
percentile goals, the number of transactions completed within
fixed percentages of the specified goals.  Observations are
written to this file only if the service class has either
average or percentile response time goals, and if the
measurements are available.
 
The WLM_EM file is commonly used in conjunction with these
related files:
 
  o  WLM_EA - Report Class
  o  WLM_EC - Report Class Resource Consumption
  o  WLM_ED - Report Class General Execution Delay
 
Information in the WLM_EM file is derived from the type 72
subtype 3 RMF Workload Activity and Storage Data record.
