zprint

ZPRINT(1)						    BSD General Commands Manual 						 ZPRINT(1)

NAME

     zprint -- show information about kernel zones

SYNOPSIS

     zprint [-cdhlLstw] [name]

DESCRIPTION

     zprint displays data about Mach zones (allocation buckets).  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, respectively.  Zones with pre-
		posterously large maximum sizes are shown with '----' in the max size and max num elts fields.

     -d 	Display deltas over time, showing any zones that have achieved a new maximum current allocation 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.

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

     -l 	(Default) Show all wired memory information after the zone information.

     -L 	Do not show all wired memory information after the zone information.

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

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

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

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

DIAGNOSTICS

     The zprint utility exits 0 on success, and >0 if an error occurs.
