can change the password by clicking Change Password and entering the
new password.
10 If you want to test and upload the Access Log now, click FTP Now. Enter a
filename for the log and click OK. The filename can only contain
alphanumeric and . (dot), - (hyphen) or _ (underscore) characters and can
only be up to 32 characters in length.
Clicking FTP Now will immediately FTP the currently active Access Log to
the FTP server. This allows you to test your FTP settings or to save the
Access Log without waiting for the next automatic FTP. Since the
Webcache may still be writing to the Access Log, using FTP Now may
result in an incomplete record at the end of the saved Access Log.
If no client machines have accessed a Web site through the Webcache
before you click FTP Now, then an empty log file will be saved on the FTP
server.
Viewing the Access
Log
To view the Access Log using the Web interface:
1 Log in to the Web interface.
2 Click Device View on the Toolbar.
3 Select System -> Caching -> View Access Log in the Navigation Tree.
4 The last 256 lines of the Access Log are displayed.
Click Refresh to update the information that is displayed.
If the Webcache is deployed in Proxy mode, multiple entries for the pages
in the Web interface itself will be made in the Access Logs. This is
standard behavior for the Webcache, as it is "seeing" the requests for the
Web interface pages and logging these requests in the Access Logs. You
should either leave the Web Interface open for only short periods of time
to reduce the entries made, or use a log analyzer tool such as Webtrends
to view and analyze the Access Logs.
Analyzing the
Access Logs
The access logs that have been saved on the FTP server are based on the
native Squid format. This is optimized for efficient generation and can be
analyzed using a wide variety of off-the-shelf log analysis tools.
