I'm trying to build a log correlation system on multiple hosts.

SEC seems interesting but I don't know if it will cover my needs.

How could I correlate system events, logs, network events, etc. on multiple hosts at the same time, in real time?

Examples:

If 5 failed logins happened on host A the last minute and if firewall B has denied lots of access on differents ports on A, then we assume there is a potential attack in progress on A.

If the Apache service on host A didn't receive any request for the last N minutes and Apache service on host B did, then the load balancing could be faulty.
