...
To keep metrics volume down it is recommended that a client only sends metrics with a recorded value.
Metrics are to be sent as CUMULATIVE values, rather than DELTA, which allows for missed/dropped transmits without data loss.
Compression
As metric names and labels are highly repeated it is recommended that the serialized metrics are compressed prior to sending them to the broker if the serialized uncompressed size exceeds 1000 bytes.

Metric name | Type | Labels | Description |
client.consumer.poll.interval | Gauge FIXME | The interval at which the application calls poll(), in seconds. | |
client.consumer.poll.last | Gauge | The number of seconds since the last poll() invocation. | |
