----------------------------------------

             Summary: Provide Kafka metrics filter to reduce write volume
                 Key: AMBARI-13173
                 URL: https://issues.apache.org/jira/browse/AMBARI-13173
             Project: Ambari
          Issue Type: Task
          Components: ambari-metrics
    Affects Versions: 2.0.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
            Priority: Critical
             Fix For: 2.1.2


- Kafka writes 1100 metrics for a topic producing a very high load on the metrics system.
- Ganglia metrics reporter provided a regex to filter out metrics that are not needed.
- This patch provides configuration knobs to filter unnecessary metrics:
- Exclude list:
{noformat}
kafka.network.RequestMetrics.*
kafka.server.DelayedOperationPurgatory.*
kafka.server.BrokerTopicMetrics.BytesRejectedPerSec.*
{noformat}
- Include list:
{noformat}
kafka.network.RequestMetrics.ResponseQueueTimeMs.request.OffsetCommit.98percentile
kafka.network.RequestMetrics.ResponseQueueTimeMs.request.Offsets.95percentile
kafka.network.RequestMetrics.ResponseSendTimeMs.request.Fetch.95percentile
kafka.network.RequestMetrics.RequestsPerSec.request.*
{noformat}
