* `io.strimzi.kafka.quotas:type=StaticQuotaCallback,name=Fetch` shows the currently configured fetch quota
* `io.strimzi.kafka.quotas:type=StaticQuotaCallback,name=Request` shows the currently configured request quota

NOTE: Only one quota plugin can be used in Kafka.
Enabling this plugin, the built-in Kafka quotas plugin will be automatically disabled.
This means that you won't see per-client quota metrics, but only aggregated quota metrics.
