NAME
cachefsstat - Cache File System statistics
SYNOPSIS
/usr/sbin/cachefsstat
[ -z ][path ... ]
DESCRIPTION
The
cachefsstat command displays statistical information about the cache filesystem mounted on
path . The statistical information includes cache hits and misses, consistency checking, and modification
operations. If path is not specified, all mounted cache filesystems are used.
cachefsstat can also be
used to reinitialize this information (see description for the
-z option). The statistical information has
the following format:
<cache hit rate>
<consistency checks >
<modifies >
where each of the above is defined as:
cache hit rate
The percentage of cache hits over the total number of attempts followed by the actual
numbers 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, and so on.
Options
cachefsstat recognizes the following option:
-z Zero (reinitialize) statistics. Execute
cachefsstat -z before executing
cachefsstat again to gather statistics on the cache performance. This option can only
be used by the superuser. The statistics printed reflect those just before the statistics are
reinitialized.
RETURN VALUE
cachefsstat returns the following values:
0 Success.
non-zero An error occurred.
EXAMPLES
% cachefsstat /home/sam
cache hit rate: 73% (1234 hits, 450 misses)
consistency checks: 700 (650 pass, 50 fail)
modifies: 321
