I'm assuming the lines you want are always the first two (change if not true):
my $log = 'somelogfile.log';
open LOG, $log;
my $lineno = 0;
while (defined ($line = <LOG>)) {
chomp $line;
++$lineno;
print "$lineno: $line\n" if $debug;
if ($lineno == 1) {
# green Thu Nov 30 14:12:07 CET 2006 All processes are OK
my @f = split ' ', $line; # split words
printf "%s: date='%s'\n", $log, join ' ', @f[1..6];
} elsif ($lineno == 2) {
if ($line =~ /^\&(green|yellow|red).*\s+(\d+)\s+instances/i) {
print "$log: Instances $2\n";
} else {
print "$log: Bad instance line $line\n";
}
} else {
last; # after two lines quit
}
}
close LOG;
__END__
