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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
