### To configure the HTTP Service Access Log

Use this page to enable and configure rotation for the access logs for the virtual servers. These logs are in the `domain_root_dir/domain_dir/logs/access` directory and are named as follows: `virtual_server_name_access_log.yyyy-mm-dd.txt`

1. Expand the Configuration node to select the HTTP Service node.

2. Click the Access Log tab.

3. Define the Access Log settings as follows:

   - Rotation: Check the File Rotation box to enable file rotation.

   - Rotation Policy: Choose a policy from the Rotation Policy drop-down list. (The only policy available is `time`).

   - Rotation Interval: Enter a numeric value to specify the number of minutes between rotations of the access log. This field is valid only if the Rotation Policy is time. The default is 1440 minutes.

   - Rotation Suffix: Enter a string value to specify the suffix to be added to the log file name after rotation. The default is `YYYY-MM-DD`.

   - Format: Enter a string value to specify the format of the access log. Use the formats shown in the following table. The default format is `%client.name% %auth-user-name% %datetime% %request% %status% %response.length%`.

     Client DNS | `%client.dns%`
     System Date | `%datetime%`

     Date Header | `%header.date%`
     If-Modified-Since Header | `%header.if-mod-since%`
     Authorization Header | `%header.auth%`
     Any valid HTTP header value defined in RFC 2616 (any is also a valid header value; it is specified as a variable here) | `%header`.any`%`
     Name of Authorized User | `%auth-user-name%`
     Value of a Cookie | `%cookie.value%`
     Virtual Server ID | `%vs.id%`
