Interface PortalStatistics

public interface PortalStatistics

The PortletStatistics interface provides an API for logging portlet statistics. Each log entry is formatted in the Apache Common Log Format (CLF) . Each CLF log entry has the following form:

"%h %l %u %t \"%r\" %>s %b"

where:

• %h - remote host
• %l - remote log name
• %u - remote user
• %t - time in common log time format
• %r - first line of HTTP request
• %s - HTTP status code
• %b - number of bytes sent ("-" if no bytes sent).

Here's an example of a CLF log entry:

 
 192.168.2.3 - johndoe [25/Oct/2005:11:44:40 PDT] "GET
 /jetspeed/DatabaseBrowserTest HTTP/1.1" 200 -
 
 

The PortletStatistics interface overloads the %r field of the CLF format, depending on the type of information being logged:

 
 LOG TYPE FORMAT OF %r FIELD -------------- ----------------------------
 Portlet access "PORTLET " Page access "PAGE
 " User logout "LOGOUT"
