Apparently the SNMP counters on the system aren't accounting for that.

It is possible to change the calculation in that plugin with the -T command

Code: Select all

-T, --type=TYPE
   pl : calculate percent left
   pu : calculate percent used (Default)
   bl : calculate MegaBytes left
   bu : calculate MegaBytes used

Also there is this flag, which is likely what you are looking for

Code: Select all

-R, --reserved=INTEGER
   % reserved blocks for superuser
   For ext2/3 filesystems, it is 5% by default

That's absolutely perfect; exactly what we're looking for. You rock as always,
