The Panther Weblogger is a easy to use, centralized service that log all HTTP traffic running through a specific internet line, usually the gateway to the datacenter. By using the Weblogger, there will be no need for logging HTTP data in local logfiles on production web-servers.

The benefits with weblogger is: 

• Centralized logfiles.
• No disc or perfomance related issues on production servers due to HTTP logging anymore
• A single data source for all statistics applications 
• Same HTTP log format (W3C)* for all servers and all applications
• Auto discovery and creation of logfiles, when new domainnames are set in production
• Easy sharing and backup of logfiles, using FTP or Samba

The weblogger can handle thousands of webservers using a single instance of the program.
