             Summary: Dropwizard metrics output in Prometheus format
                 Key: CASSANDRA-17968
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17968
             Project: Cassandra
          Issue Type: Improvement
          Components: Observability/Metrics
            Reporter: Sarma Pydipally


in Apache Cassandra :

we already have Dropwizard metrics module pre-integrated. I wrote about it on 
my GitHub : 
https://github.com/sarma1807/Prometheus-Grafana-Cassandra/tree/main/01_Cassandra_metrics-reporter

we should have a feature where Cassandra Dropwizard module can directly write 
these metrics into Prometheus format.

then we can feed those metrics directly to Prometheus for metrics collection.

we do not have to expose this as a webservice - instead of writing just metrics 
in plain text ... it should write in Prometheus format into a file on each 
server.
