HPE Ezmeral Data Fabric Streams Metrics

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

WARNING
Data Fabric monitoring uses 2 MB disk space per minute per node when HPE Ezmeral Data Fabric Streams 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 EEP 2.0.
mapr.streams.produce_msgs The number of Streams messages produced. This metric is available as of EEP 2.0.
mapr.streams.produce_bytes

The number of megabytes produced by Streams messages.

This metric is available as of EEP 2.0.

mapr.streams.listen_rpcs The number of Streams consumer RPCs. This metric is available as of EEP 2.0.
mapr.streams.listen_msgs The number of Streams messages read by the consumer. This metric is available as of EEP 4.0.
NOTE
If you upgrade to EEP 4.0, all Streams messages are consumed, however this metric only reports a count on messages that were produced in EEP 4.0. Messages produced prior to EEP 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 EEP 4.0.
mapr.streams.listen_currpcs The number of concurrent Stream consumer RPCs. This metric is available as of EEP 2.0.
mapr.streams.listen_bytes The number of megabytes consumed by Streams messages. This metric is available as of EEP 2.0.
