It is quite hard to extract relevant information from system log files:
There is no complete list of all messages that a system might generate.
The format of each message is not documented. Even when a message is already known because it was logged, it's not known whether optional fields were missing.
Message formats often change in newer revisions of a system.
Not all messages are parsable. Field separators like spaces might be contained in field data by accident or might intentionally be injected by an attacker.
