NAME
cachefsstat - Cache File System statistics
SYNOPSIS
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 opera-
tions. If path is not specified, all mounted cache filesystems 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:
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, 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 used by the super-user. The statistics printed reflect those just before the statistics are
re-initialized.
EXAMPLES
example% cachefsstat /home/sam
cache hit rate: 73% (1234 hits, 450 misses)
consistency checks: 700 (650 pass, 50 fail)
modifies: 321
EXIT STATUS
The following exit values are returned:
0 Success.
non-zero An error has occurred.
