Splitting lighttpd Logs With vlogger And Creating Statistics With Webalizer

Post date: January 31, 2008, 13:01 Category: Miscellaneous Views: 3227 Comments
Tutorial quote: Vlogger is a little tool with which you can write lighttpd logs broken down by virtual hosts and days. With vlogger, we need to put just one accesslog.filename directive into our global lighttpd configuration, and it will write access logs for each virtual host and day. Therefore, you do not have to split lighttpd's overall access log into access logs for each virtual host each day, and you do not have to configure lighttpd to write one access log per virtual host (which could make you run out of file descriptors very fast). At the end of this tutorial I will show you how to use webalizer to create statistics from the lighttpd access logs.

It can also become a liability when hardware or applications fail, leaving potential customers unable to reach your servers. A properly designed and executed failover configuration for your primary firewall will address many of these concerns. This article introduces a proven method for installing redundant stateful firewalls using native OpenBSD features.
