cachefsstat(1M)		System Administration Commands	       cachefsstat(1M)

NAME
       cachefsstat - Cache File System statistics

SYNOPSIS
       /usr/bin/cachefsstat [-z] [path...]

DESCRIPTION
       The  cachefsstat	 command  displays  statistical	 information about the
       cache file system mounted on path. The statistical information includes
       cache  hits  and	 misses, consistency checking, and modification opera‐
       tions. If path is not specified, all mounted  cache  file  systems  are
       used.

       cachefsstat  can	 also be used to reinitialize this information (see -z
       option).

       The statistical information has the following format:

       <cache hit rate>
       <consistency checks>
       <modifies>
       where:

       hit rate		       The percentage of cache	hits  over  the	 total
			       number of attempts, followed by the actual num‐
			       bers of hits and misses.

       consistency checks      The number  of  consistency  checks  performed,
			       followed	 by  the  number  that passed, and the
			       number that failed.

       modifies		       The  number  of	modify	operations,  including
			       writes, creates, etc.

OPTIONS
       The following option is supported:

       -z	Zero  (reinitialize) statistics. Execute cachefsstat -z before
		executing cachefsstat again to gather statistics on the	 cache
		performance.  This  option  can	 only be use by the superuser.
		The statistics printed reflect those just before  the  statis‐
		tics are reinitialized.

USAGE
       See  largefile(5)  for  the  description of the behavior of cachefsstat
       when encountering files greater than or equal to 2 Gbyte (2**31 bytes).

EXAMPLES
       Example 1: Using cachefsstat

       The following example shows the cachefsstat command run on file	system
       /test:

       example# cachefsstat /test
	 /test
	      cache hit rate:	   100% (0 hits, 0 misses)
	      consistency checks:    0	(0 pass, 0 fail)
	      modifies:		     0
       garbage collection:	     0

EXIT STATUS
       The following exit values are returned:

       0	       Successful completion.

       non-zero	       An error occurred.
