TCPWebLog is a system that collects and aggregates Apache and Varnish Web server logs from multiple Linux computers. It uses a simple "client" program that pipes logs to a central server over a TCP connection, and a "server" program that receive the logs and quickly aggregates or splits them.
LogPipe is a module that extends the default PHP error handling function. It allows you to send logs to syslog, or pipe them to an external program. It extends a standard log line to contain the IP address and host name of the server under which the current script is executing, and the client IP address. The IP address and host name can be used by an external program to split or aggregate logs based on the virtual host. This module has been designed mainly as a complement for the TCPWebLog project.
