So you're saying that I should end up with:
        next unless /^\S+\s+:\s+[\d\.]/; #filter out error messages from 
        @times = split /\s+/;
        my $ip = shift @times;
    print STDERR @times;
        next unless ':' eq shift @times; #drop the colon
    print STDERR @times;

I've done all that, but I'm still not seeing anything in the apache log 
file either.

Just out of curiosity, did you actually get/read my message wondering if 
it was some sort of permissions problem?



 FWIW I'm running Ubuntu 8.04, and just installed Smokeping through
 their software repository.  As part of that installation, it seems to
 have created a seperate 'smokeping' user + group, so could that
 possibly have something to do with the problem?

 I'm still [relatively] new to the whole Linux world, so I'm sure that
 I don't quite have my head around all these permissions/etc properly yet.

 Is there an easy way to check and/or rule out any sort of permission
 error as the source of my problem?
