analyze power i apache logs for browser types

Is there tooling out there (hopefully free) to analyze what browsers are
hitting a power i site?

Have done a crude thing with a rpgle pgm but so many variations and
releases.

This is a rpg cgi site if it matters, v7r1.

Need to know what population of browsers being served.



Sample records from access log
