Assuming these are apache logs, a totally different approach can be found at mod_log_spread.

To quote from that page:

mod_log_spread is a patch to Apache's mod_log_config, which provides an interface for spread to multicast access logs. It utilizes the group communication toolkit Spread, developed at Johns Hopkins University's Center for Networking and Distributed Systems. 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 webservers. Current version is 1.0.4.
