>
>
> The property of dmax in ganglia is a configurable time to rotate metrics.
> Therefore, no more value of the metric will be emit to the gmond, after
> 'dmax' seconds, then gmond will destroy the metric in memory. In Hadoop
> metrics framework, the default value of 'dmax' is 0. It means the gmond will
> never destroy the metric although the metric is disappeared. The gmetad
> daemon also does not delete the rrdtool file forever.
> We need to add a method to configure the default value of dmax for all
> metrics in hadoop.properties.
