I've recently set up syslog-ng to collect syslog from about 60 machines
(and counting), don't know if I'll reach there.

I'd like to know of good Free Software replacement(s) for Splunk,
oriented to log analysis, if anyone can speak of any.

Right now, another absolutely crappy solution from a famous
3-letter-acronym company is being used, even though the users would
prefer Splunk.

I'd like to show off something about as good as Splunk for log analysis.
