pcp - How to change the instance domain for filesystem metrics

Solution In Progress - Updated -

Issue

  • Currently the instance domain for the filesys.* metrics is the device mapper name, e.g. /dev/dm-3
ls -l /dev/mapper/rootvg-varloglv
lrwxrwxrwx 1 root root 7 Apr 20 19:51 /dev/mapper/rootvg-varloglv -> ../dm-3
  • So in this case, the device mapper device for /dev/dm-3 (not very useful), is rootvg-varloglv (which IS useful).

Environment

  • pcp prior to pcp-3.11.3-3
  • Red Hat Enterprise Linux 7
