Hi,
I have a customer who is using your graph templates and I noticed that in the graph the 'Uncheckpointed bytes' is often higher than the InnoDB Log size, which to me is wrong.

$_[0]->{ib_log_flush} - $_[0]->{ib_log_checkpoint}

I'm not sure where those two numbers come from, but to me 'Uncheckpointed bytes' should really just be the equivalent of the 'Checkpoint age' in SHOW ENGINE INNODB STATUS, no?
