	 average between two plots (i.e. 5 minutes). Short peaks will therefore be hard to spot, but long peaks
	 will be spottable, even though it occurs between plots.</td>

	 that the counter value is set to 0 upon each read of it. It's not a good idea to run these plugins by
	 hand in-between Munin runs, since Munin won't receive all the data it expects.</td>
