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

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

<format_specifier1> <format_specifier2>

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

, 

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.
