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 operations. If path is not speci-
fied, all mounted cache file systems are used.
cachefsstat can also be used to reinitialize this informa-
tion (see -z option).
The statistical information has the following format:
where:
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 per-
formed, 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 statis-
tics on the cache performance. This option can only be
use by the superuser. The statistics printed reflect
those just before the statistics are reinitialized.
