       slabtop - display kernel slab cache information in real time

       slabtop [options]

       slabtop	displays  detailed kernel slab cache information in real time.
       It displays a listing of the top caches sorted by  one  of  the	listed
       sort  criteria.	 It also displays a statistics header filled with slab
       layer information.

       Normal invocation of slabtop does not require any options.  The	behav‐
       ior,  however,  can be fine-tuned by specifying one or more of the fol‐
       lowing flags:

       -d, --delay=N
	      Refresh the display every n in  seconds.	 By  default,  slabtop
	      refreshes the display every three seconds.  To exit the program,
	      hit q.

       -s, --sort=S
	      Sort by S, where S is one of the sort criteria.

       -o, --once
	      Display the output once and then exit.

       -V, --version
	      Display version information and exit.

       -h, --help
	      Display usage information and exit.

       The following are valid sort criteria used to sort the individual  slab
       caches and thereby determine what are the "top" slab caches to display.
       The default sort criteria is to sort by the number of objects ("o").

       The sort criteria can also be  changed  while  slabtop  is  running  by
       pressing the associated character.

       character   description		      header
       a	   number of active objects   ACTIVE
       b	   objects per slab	      OBJ/SLAB
       c	   cache size		      CACHE SIZE
       l	   number of slabs	      SLABS
       v	   number of active slabs     N/A
       n	   name			      NAME
       o	   number of objects	      OBJS
       p	   pages per slab	      N/A
       s	   object size		      OBJ SIZE
       u	   cache utilization	      USE

       slabtop	accepts	 keyboard commands from the user during use.  The fol‐
       lowing are supported.  In the case of letters, both cases are accepted.

       Each of the valid sort characters are also accepted, to change the sort
       routine. See the section SORT CRITERIA.

       Currently, slabtop requires a 2.4 or later kernel (specifically, a ver‐
       sion 1.1 or later /proc/slabinfo).  Kernel 2.2 should be	 supported  in
       the future.

       The  slabtop  statistic	header is tracking how many bytes of slabs are
       being used and it not a measure of physical memory.  The	 'Slab'	 field
       in the /proc/meminfo file is tracking information about used slab phys‐
       ical memory.

       slabtop was inspired by Martin Bligh's perl script, vmtop.
