You are including the time stamps in the key, so identical events a second apart increment separate counts. or maybe you were showing the overall concept, and leaving the trimming as an exercise for the student?

It looks like gen-vcs11 kernel is a standard component of every line, so I would ignore it. Using split to extract the second and third components, and using those as a key:

my ( $code, $msg ) = ( split, ':', $_)[2,3];
$msgs{$code}{$msg}++;

It becomes even simplar if you only want to preserve the msg component.

As Occam said: Entia non sunt multiplicanda praeter necessitatem.
