Firewall Log Analysis - Computer vs. Human

Hi all, We are trying to develop a log analyzer that would "replicate" a human's approach to log analysis - by that I mean the fact that a human can correlate information in the log with other factors (like - "hmm, the log says that the firewall was restarted at 12:03 PM"... oh, yeah, it was that UPS failure yesterday around noon). For this particular example, the log analyzer could say in the report: "12:03 PM - Firewall restarted - Possible power failure, power disconnection or manual restart" - a bit vague I agree but it is better than nothing - and in fact, this is what the firewall admin would go through, right? Thinking, "Why would there be a restart? I did not restart it.. anything happened at noon? The UPS failure!". Or for example, instead of saying IP 123.123.123.123 was denied for protocol TCP/8543 and let the firewall admin worry about it maybe the analyzer should do a bit of analysis, check the "history", see that this protocol is not something commonly used, it's not one of the common worms and decide to report that it is in fact a stray TCP packet caused by Internet latency (TCP port higher than 1024, not a "known protocol", coming from an IP address that is typically accessed by internal IPs via HTTP - all this information is should be obtainable from the logs). Now, the question is, what are the things (in your opinion) that only a human can do?
