I am not sure which point of time are you interested in, so I am
attaching /proc/vmstat log of 3 points.

too_many_isolated_vmstat_before_frag.txt
   This one is taken before I ran my test app which attempts
   to make fragmentation
too_many_isolated_vmstat_before_compaction.txt
   This one is taken after running the test app and before
   running compaction.
too_many_isolated_vmstat_during_compaction.txt
   This one is taken a few minutes after running compaction.
   To take this I ran compaction in background.

Thanks
Iram
