IV36542: AVG % PROCESSOR TIME > 100 IN PROCESS ATTRIBUTES

IBM Tivoli Monitoring 6.2.3 Fix Pack 5 (6.2.3-TIV-ITM-FP0005)

APAR status

• Closed as program error.

Error description

• PROBLEM DESCRIPTION:
  In the Process attributes group, the "Avg % Processor Time" is
  showing as greater than 100 % . This attribute is averaged on
  the number of processors, therefore it should not exceed 100.
  However, sometimes the ITM agent is receiving inconsistent
  values from the monitored platform. Currently those values are
  not filtered out. On the contrary, they should not be used.
  

Local fix

Problem summary

• "Avg % Processor Time" > is showing as greater than 100 percent.
  
  
  In the Process attributes group, the "Avg % Processor Time" is
  showing as greater than 100 % .  This attribute is averaged on
  the number of processors, therefore it should not exceed 100.
  However, sometimes the agent receives inconsistent values from
  the monitored platform.  In addition to that, the number of
  processors is wrongly calculated when hyperthreading is enabled.
  And the calculation of the average is incorrect.
  
  A similar problem for the average also exists for the attribute
  "High Process Average Utilization" in the "Processor Summary"
  Attributes group.
  

Problem conclusion

• The number of logical processors has been properly calculated
  and a check has been introduced on the % Processor time to avoid
  inconsistent input from the operating system.  When such
  inconsistency is found, the value is reset to zero.
  
  
  The fix for this APAR will be contained in the following
  maintenance package:
