IJ05075: ALLOW PREVIOUS ALGORITHM FOR NET MEMORY USED (PERCENT) TO BE USED FOR UNIX OS AGENT

IBM Tivoli Monitoring: Linux(R) OS Agent 6.3.0.7-TIV-ITM_LINUX-IF0002
IBM Tivoli Monitoring 6.3.0 Fix Pack 7 Service Pack 1 (6.3.0.7-TIV-ITM-SP0001)
IBM Tivoli Monitoring: Linux(R) OS Agent 6.3.0.7-TIV-ITM_LINUX-IF0003

APAR status

• Closed as program error.

Error description

• APAR IV82704 was introduced to use the MemAvailable field from
  the /proc/meminfo file instead of calculating the value from
  other fields in that file. Customer would like the ability to
  use the previous algorithm, so we will add an envornment
  variable to able to use to the previous algorithm.
  Prevous algorithm:
  Net Memory Used (MB) = Memory Used (MB) - Memory in Buffers
  (MB) - Memory Cached (MB)
  Algorithm with IV82708:
  Net Memory Used (MB) = (MemTotal - MemAvailable)
  Approver: MK
  
  Reported Release: 630 FP7
  Environment: 630 FP7
  

Local fix

• Use the OS Agent Scripting feature to calculate the value and
  set it to an attribute. Example to be sent by SME.
  

Problem summary

• Allow previous algorithm for Net Memory Used to be used.

  In order for this APAR to be properly implemented in your
  environment, a new environment variable has been added.  See the
  "Install Actions" section of the APAR conclusion for more
  details.
  

Problem conclusion

• Install Actions:
  
  In order for this APAR to be properly implemented in your
  environment, a new environment variables has been added:
  KLZ_NETMEMUSED_PREV_CALC.  The variable should be set to TRUE to
  have the agent use the algorithm for Net Memory Used which was
  used prior to introduction of IV82708.
     KLZ_NETMEMUSED_PREV_CALC=TRUE
  
  The default if the environment variable is not set, is to
  continue to use the new alrogithm introduced by APAR IV82708.
  
  
  The fix for this APAR is contained in the following maintenance
  packages:
  
     | service pack | 6.3.0.7-TIV-ITM-SP0001
     | interim fix | 6.3.0.7-TIV-ITM_LINUX-IF0002
