Yeah but then u can get sequence like "over, over, under, over, over,
under" and it will never trigger, but in most cases it will work
okay,and in that 2% you can just make threshold bit lower and still it
will be working good enough :)

>>> Hi

>>> <Threshold>
>>>  <Plugin load>
>>>    <Type load>
>>>       WarninMax 1
>>>       Hits 3
>>>    </Type>
>>>   </Plugin>
>>> </Threshold>
>>> In this example the notification will be generated when load value is
>>> greater than 1 for 3 intervals.
>>> Here are two patches, the first one adds hit feature to the collectd
>>> cached and the second one use hits in thresholds,
>>> Of course comments and suggestions are welcome :)
>>> Enjoy!
