cachefslog - Cache File System logging
SYNOPSIS
cachefslog [-f logfile | -h] cachefs_mount_point
DESCRIPTION
The cachefslog command displays where CacheFS statistics are being logged. Optionally, it sets where CacheFS statistics are being logged,
or it halts logging for a cache specified by cachefs_mount_point. The cachefs_mount_point argument is a mount point of a cache file system.
All file systems cached under the same cache as cachefs_mount_point will be logged.
OPTIONS
The following options are supported. You must be super-user to use the -f and -h options.
-f logfile Specify the log file to be used.
-h Halt logging.

USAGE

EXAMPLES
Example 1: Checking the Logging of a directory.
The example below checks if the directory /home/sam is being logged:

Example 2: Changing the logfile.
The example below changes the logfile of /home/sam to /var/tmp/samlog:
example# cachefslog -f /var/tmp/samlog /home/sam
/var/tmp/samlog: /home/sam
Example 3: Verifying the change of a logfile.
The example below verifies the change of the previous example:
example% cachefslog /home/sam
/var/tmp/samlog: /home/sam
Example 4: Halting the logging of a directory.
