Brandon Heller has been doing some work with this but I don't think he's gotten to M109/M190. Check pull requests on the github repo and my blog, where Brandon has started writing some posts: http://bb-lcnc.blogspot.com/ - -- Charles Steinkuehler [email protected] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlHlKRgACgkQLywbqEHdNFyu2wCg8v5wHCC8CXxK5Gx2ynKbeBiF EAoAoKPeNpxf0Dg7eYFRB0oEJR8tSk9X =kknI -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
