mod_log_spread is a patch to Apache's mod_log_config, which provides an interface for spread to multicast access logs and per-vhost logs. It utilizes the group communication toolkit Spread for reliable multicast transport. mod_log_spread was developed to solve the problem of collecting consolidated access logs for large web farms. In particular, the solution needed to be scalable to hundreds of machines, utilize a reliable network transport, allow machines to added or dropped on the fly, and impose minimal performance impact on the Web servers.
The Graffiti Server is a small C program that allows the posting of messages and, optionally, HTML. It displays the most recent messages but has a search function for finding entries with a given keyword or string. Users can post and delete their own messages, while the administrator can delete any message. As configured, the server remembers about 2500 messages. The Graffiti Server is a traditional Unix daemon that installs itself on a port, waits for connections, then forks another copy to handle the request.
