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. |
