Re: [pcp] Queston about pcp performance metrics filesys.used

Nathan,

Thanks I will look into this. Any reason
why this is done from the disk.dm. metrics but not the filesys. metrics?

The former (rootvg-homelv) is indirectly available via hinv.map.dmname
but
the latter (/home -> mount point) is not necessarily a one-to-one mapping
with device, so gets more complicated.

You might also find pmdamounts(1) of use for your situation, in recent
PCP
versions it exports all of the same metrics as filesys.* for a specified
set of mount points.

cheers.
