If you're using COUNTER in your munin plugin, you'll get large spikes
when the counter you're tracking resets.  If this is the case, you
should use DERIVE instead for the peaking graph.

If the varnish worker process restarts, it will start out empty (shown
as the hit/miss graph dropping to 0% hit, and rising, then flattening
out at the previous level after a while), and the counters will reset
(shown as the large spike when COUNTER is used by rrdtool update).
