HPE Ezmeral Data Fabric Event Store Metrics

Every 10 seconds, the collectd service uses a plugin to gather the following Streams metrics on each node in the cluster.

Warning: MapR monitoring uses 2 MB disk space per minute per node when HPE Ezmeral Data Fabric Event Store metrics is enabled. This is approximately 3 GB per day on a single node or 7 GB per node per day with a 3X replication. This stream metrics data is automatically deleted every 3 days.

Name	Description
mapr.streams.produce_rpcs	The number of Streams producer RPCs. This metric is available as of MEP 2.0.
mapr.streams.produce_msgs	The number of Streams messages produced. This metric is available as of MEP 2.0.
mapr.streams.produce_bytes	The number of megabytes produced by Streams messages. This metric is available as of MEP 2.0.
mapr.streams.listen_rpcs	The number of Streams consumer RPCs. This metric is available as of MEP 2.0.
mapr.streams.listen_msgs	The number of Streams messages read by the consumer. This metric is available as of MEP 4.0. Note: If you upgrade to MEP 4.0, all Streams messages are consumed, however this metric only reports a count on messages that were produced in MEP 4.0. Messages produced prior to MEP 4.0 are consumed, but not counted. In this scenario, the metric reports a partial count or a zero count if all messages were produced prior to MEP 4.0.
mapr.streams.listen_currpcs	The number of concurrent Stream consumer RPCs. This metric is available as of MEP 2.0.
mapr.streams.listen_bytes	The number of megabytes consumed by Streams messages. This metric is available as of MEP 2.0.
