To Set the Access Log Preferences for the Server Instance

1. Access the Server Manager and click the Server Status tab.

2. Click the Set Access Log Preferences link.

   The Set Access Log Preferences page is displayed.

3. Select the resource from the drop-down list or click the Regular Expression button, type a regular expression, and click OK.

4. Specify whether to log client accesses.

   This setting requires Domain Name Service (DNS) to be enabled.

5. Specify the absolute path for the access log file.

   The log files by default are kept in the logs directory in the server root. If you specify a partial path, the server assumes the path is relative to the logs directory in the server root.

   If you are editing the entire server, the default value for this field is $accesslog, the variable that denotes the access log file for the server in the configuration file.

6. Choose whether to record domain names or IP addresses of the systems accessing the server in the access log.

7. Choose the format the log file should be: common, extended, extended-2, only specified information (“Only log” radio button), or custom.

   If you click Only log, the following flexible log format items are available:

8. Choose the type of log file format to use in the access log.

   Server access logs can be in Common Logfile Format, Extended Logfile Format, Extended2 Logfile format, flexible log format, or your own customizable format. The Common Logfile Format is a commonly supported format that provides a fixed amount of information about the server. The flexible log format enables you to choose (from Proxy Server) what to log. A customizable format uses parameter blocks that you specify to control what gets logged.

   • Use Common LogFile Format. Includes client’s host name, authenticated user name, date and time of request, HTTP header, status code returned to the client, and content length of the document sent to the client.

   • Use Extended LogFile Format. Includes all of the fields of the common log file format as well as some additional fields such as remote status, proxy to client content length, remote to proxy content length, proxy to remote content length, client to proxy header length, proxy to client header length, proxy to remote header length, remote to proxy header length and transfer time.

   • Use Extended2 LogFile Format. Includes all of the fields of the extended logfile format as well as some additional fields such as client status, server status, remote status, cache finish status, and actual route.

   • Only Log. Allows you to choose which information will be logged. You can choose from the flexible log format items listed in Table 9–3.

   • If you choose a custom format, type it in the Custom Format field.

9. If you do not want to log client access from certain host names or IP addresses, type them in the host names and IP Addresses fields.

   Type a wildcard pattern of hosts from which the server should not record accesses. For example, *.example.com does not log accesses from people whose domain is example.com. You can type wildcard patterns for host names, IP addresses, or both.

10. Choose whether to include the format string in the log file.

    If you are using the Proxy Server’s log analyzer, you should include a format string. If you are using a third-party analyzer, you may not want to include a format string in your log file.

11. Click OK.

12. Click Restart Required.

    The Apply Changes page appears.

13. Click the Restart Proxy Server button to apply the changes.
