[1]\n\nInstead of collecting the MeanRate, we could collect the load average\nstyle rates or we can simply grab the monotonically increasing counts\nand calculate our own rate from that raw counters. Since DD captures\nmetrics at smaller time intervals than a minute, calcuating our own rate\ngives the user the most granular view of cluster activity so that's what\nthe example configuration file will contain.\n\nIn addition to fixing the collection of these rate metrics, the example\nconfiguration is also updated to collect nearly all the useful metrics\nrecommended by Confluent for alerting and trending on a Kafka cluster.\n[2]\n\n[1] http://metrics.dropwizard.io/3.1.0/manual/core/#meters\n[2] http://docs.confluent.io/1.0.1/kafka/monitoring.html","distinct":true,"url":"https://api.github.com/repos/dougbarth/dd-agent/commits/069d8c31ff28484d2f1ae87883e28d674f9089a7"}]}
