No MBean matched for additional metrics

[ProtemS]

I can successfully get the configured produce quota metric via
io.strimzi.kafka.quotas:type=StaticQuotaCallback,name=Produce

But when I attempt any of the metrics in the additional metrics it is not recognized by JMX,
An example of how the ObjectName/Metric configuration should be called would be helpful

io.strimzi.kafka.quotas:type=StaticQuotaCallback,name=ThrottleFactor
Doesn't work, it says the metric is not recognized, im using the GenericJMX plugin for collectd, but this may be a mis-configuration, Adding the observingBrokerId to to the end of the metric definition also didn't work.

Help would be greatly appreciated :)
