How to View Cache Statistics

View the statistics with the cachefsstat(1M) command. You can do this at any time. For example, you do not have to set up logging in order to view the statistics.

$ cachefsstat mount-point


Specifies the cached file system for which you want to view the statistics. 

If you do not specify the mount point, statistics for all mounted CacheFS file systems will be displayed.
