How to View the Working Set (Cache) Size

You might want to check if you need to increase the size of the cache. Or, you might want to determine the ideal cache size based on your activity since you last used the cachefslog command for a particular mount point.

1. Become superuser on the client system.

2. View the current cache size and highest logged cache size.

   # cachefswssize log-file-path

   For more information, see cachefswssize(1M).

Example 19–15 Viewing the Working Set (Cache) Size

In the following example, the end size is the size of the cache at the time you issued the cachefswssize command. The high water size is the largest size of the cache during the timeframe in which logging occurred.

# cachefswssize /var/tmp/samlog
 
    /home/sam
	       end size:  10688k
	high water size:  10704k
 
    /
	       end size:   1736k
	high water size:   1736k
 
    /opt
	       end size:    128k
	high water size:    128k
 
    /nfs/saturn.dist
