Access Logging Configuration

[]

The AccessLog documents the requests accessing the webserver. It creates a technical documentation of network access and communication. Requests blocked or filtered from access to the OnlineChannel are documented within the access log only.

Access log configuration is related to LoggingConfiguration as it uses the same backend: http://logback.qos.ch/LOGBack</a>

Patterns and Request Attributes

A request can be enriched by adding custom or standardized attributes. While getting routed to a host and instance of the satellite, the system adds custom attributes to the request. The following keys -embedded into %%reqAttribute{KEY}- can be used within the <pattern> definitions of log messages to output those attribute values.

• X-Cs-Log-Host the hostname of the virtual host handling the request (if any)
• X-Cs-Log-InstanceId the instanceId of the virtual host handling the request (if any)
• X-Cs-Log-InstanceId-Host the instanceId concatenated by the hostname of the virtual host handling the request (if any)
• X-Cs-Request-Id Unique ID of the request created and set by; equal to cs.requestId within LoggingConfiguration
