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

, 

body_bytes

 is the descriptive token 

for 

%b

, and

 error_type

 is the descriptive token for 

%E

.

You can create a custom field for any header in a client request or a server response. For more 
information, see 

Use the System Administration > Log Subscriptions page to configure custom formatting for W3C log 
file entries. Click the W3C log file name to edit the W3C log subscription.

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

You can create a custom field for any header in a client request or a server response. For more 
information, see 

If the list of predefined access log and W3C log fields does not include all header information you want 
to log from HTTP/HTTPS transactions, you can type a user defined log field in the Custom Fields text 
box when you configure the access and W3C log subscriptions.
