Choose System Administration > Log Subscriptions.

Click the access log file name to edit the access log subscription.

Enter the required format specifiers in the Custom Field.

The syntax for entering format specifiers in the Custom Field is as follows:

<format_specifier_1> <format_specifier_2> ...

For example: 

%a %b %E

You can add tokens before the format specifiers to display descriptive text in the access log file. 
For example:

client_IP %a body_bytes %b error_type %E

where 

client_IP

 is the description token for log format specifier 

%a

, and so on. 

You can create a custom field for any header in a client request or a server response.

Choose System Administration > Log Subscriptions 

Click the W3C log file name to edit the W3C log subscription.

Type a field in the Custom Field box, and click Add.

The order the fields appear in the Selected Log Fields list determines the order of fields in the W3C 
access log file. You can change the order of fields using the Move Up and Move Down buttons. You can 
remove a field by selecting it in the Selected Log Fields list and clicking Remove.

You can enter multiple user defined fields in the Custom Fields box and add them simultaneously as long 
as each entry is separated by a new line (click Enter) before clicking Add.

When you change the log fields included in a W3C log subscription, the log subscription automatically 
rolls over. This allows the latest version of the log file to include the correct new field headers. 

You can create a custom field for any header in a client request or a server response.
