IJ03910: TO HAVE A MORE ACCURATE VALUE FOR THE MEMORY IN LINUX TARGETS

APAR status

• Closed as program error.

Error description

• When determining the memory on Linux targets, the third used
  command (in case of failure of both "dmidecode (--type memory |
  grep "Size"" and "cat /var/log/dmesg | grep Memory:" commands)
  is "free -m | grep Mem | awk '{print $2}'". The returned output
  is in Mb. TADDM converts it in bytes by multiplying it by 1024
  twice. I think that by substituting the command with "free -b |
  grep Mem | awk '{print $2}'" and avoiding the conversion will
  give us a more accurate result. Please evaluate the suggested
  code change.
  

Local fix

Problem summary

• When determining the memory on Linux targets, three commands
  are used:
    - dmidecode (--type memory | grep "Size"
    - cat /var/log/dmesg | grep Memory
    - free -m | grep Mem | awk '{print $2}'
  When the first and second commands fail, the third command is
  used, which returns the output in MB. TADDM converts it in
  bytes by multiplying it by 1024 twice. This does not give a
  very accurate value.
  By changing the command to
     - free -b | grep Mem | awk '{print $2}'
  This conversion can be avoided and a more accurate result can
  be obtained.
