Proposed change

Currently the Client holds a stats dictionary, keeping track of certain metrics (mainly around received and published messages). It basically holds counters that are incremented on these operations.

There is currently no easy way to hook into these statistics and process them differently, for instance sending metrics to your favourite metrics and observability system.

The new stats collection needs to be backwards compatible (the stats attribute is a public attribute), while offering extensibility at the same time.

Use case

Send custom metrics to datadog on messages received and published by the client application
