kgmetrics

kgmetrics is a plug-in package to provide rcrowley/go-metrics metrics through a kgo.Hook.

This package tracks the following metrics under the following names, all metrics are meters:

    broker.<id>.connects
    broker.<id>.connect_errors
    broker.<id>.disconnects
    broker.<id>.write_errors
    broker.<id>.write_bytes
    broker.<id>.read_errors
    broker.<id>.read_bytes
    broker.<id>.topic.<topic>.produce_bytes
    broker.<id>.topic.<topic>.fetch_bytes

Note that seed brokers use broker IDs starting at math.MinInt32.

To use,

m := kgmetrics.NewMetrics()
cl, err := kgo.NewClient(
	kgo.WithHooks(m),
	// ...other opts
)

You can use your own metrics registry, as well as specify a prefix on metrics. See the package documentation for more info!
