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 what the ideal cache size is 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—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 time frame 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
	       end size:   1472k
	high water size:   1472k
 
    /data/abc
	       end size:   7168k
	high water size:   7168k
 
    /nfs/venus.svr4
	       end size:   4688k
	high water size:   5000k
 
    /data
	       end size:   4992k
	high water size:   4992k
 
    total for cache
	   initial size: 110960k
	       end size:  30872k
