Yup - that's right. You need a mapping file like [this 
one|https://github.com/snazy/prometheus-metrics-exporter/blob/master/mappings/cassandra-mappings.yaml]
 in the {{conf}} directory and add 
{{-Dorg.caffinitas.prometheus.config=cassandra-mappings.yaml}}. That helps to 
shorten the names that appear e.g. in Grafana and to re-organize the metrics as 
you personally prefer and to exclude metrics you don't want (like 
{{org.apache.cassandra.metrics.Table.EstimatedPartitionCount}}, which touches 
all sstables).

+1 the C* changes look fine to me. 

I should note though that when I dropped in the necessary jars to smoke test 
with the Prometheus exporter, I'm seeing an awful lot of
