ZPRINT(1)                                                                                          ZPRINT(1)



NAME
       zprint - show information about kernel zones

SYNOPSIS
       zprint [-w] [-s] [-c] [-h] [-t] [-d] [-p <pid>][name]

DESCRIPTION
       zprint(1)  displays  data  about Mach zones.  By default, zprint will print out information about all
       Mach zones.  If the optional name is specified, zprint will print information  about  each  zone  for
       which name is a substring of the zone's name.

       zprint interprets the following options:

       -c      (Default)  zprint  prints  zone  info in columns. Long zone names are truncated with '$', and
               spaces are replaced with '.', to allow for sorting by column.  Pageable and collectible zones
               are  shown  with  'P' and 'C' on the far right. Zones with preposterously large maximum sizes
               are shown with '----' in the max size and max num elts fields.

       -h      (Default) Shows headings for the columns printed with the -c option.  It  may  be  useful  to
               override this option when sorting by column.

       -s      zprint sorts the zones, showing the zone wasting the most memory first.

       -w      For  each  zone,  zprint calculates how much space is allocated but not currently in use, the
               space wasted by the zone.

       -t      For each zone, zprint calculates the total size of allocations from the zone over the life of
               the zone.

       -d      Display  deltas over time, showing any zones that have achieved a new maximum current alloca-tion allocation
               tion size during the interval.  If the total allocation sizes are  being  displayed  for  the
               zones in question, it will also display the deltas if the total allocations have doubled.  -p
               <pid> Display zone usage related to the specified process id.  Each zone will  display  stan-dard standard
               dard  columns  and  the amount of memory from that zone associated with a given process.  The
               letter "A" in the flags column indicates that this total is being accounted to  the  process.
               Otherwise, the total is an indication of the influence the process has on the kernel, but the
               memory is being accounted to the kernel proper.

       Any option (including default options) can be overridden by specifying the option in upper-case;  for
       example, -C overrides the (default) option -c.
