Projects / mod_log_spread


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.
