[pcp:master] New Comment on Issue #276 Correct mem.vmstat.pgsteal* mem.vmst=
at.pgscan metrics on RHEL7 and Fedora 25 ( https://github.com/performanceco=
pilot/pcp/issues/276 )
By wcohen ( https://github.com/wcohen ) :

I am not sure how many of these missing metrics in /proc/vmstat are genera=
lly useful in addition to the pgscan and pgsteal ones. Wrote a one line scr=
ipt to see /proc/vmstat metrics listed are missing from PCP mem.vmstat.*:

one | awk '$2 < 0 {print $1}' |sort
