------------------------------------

             Summary: some metrics are missing when using GraphiteReporter with parameter prefix
                 Key: CASSANDRA-13353
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13353
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
         Environment: cassandra 3.10, metrics-graphite from https://repo1.maven.org/maven2/io/dropwizard/metrics/metrics-graphite/3.1.4/metrics-graphite-3.1.4.jar
            Reporter: Roland O


we have currently the problem that some metrics are not getting reported properly to graphite when using the prefix property in the metricsreporterconfigfile

here is our actual config

{noformat}
graphite:
  -
    period: 10
    timeunit: 'SECONDS'
    prefix: 'demo01'
    hosts:
     - host: 'our_graphite_host'
       port: 2003
    predicate:
      color: "white"
      useQualifiedName: true
      patterns:
        - "^org.apache.cassandra.metrics.+"
{noformat} 

we do some queries with cql against that host, but no metrics for

```demo01.org.apache.cassandra.metrics.ClientRequest.Latency.Read.count```

are getting reported.

when omitting the ```prefix: 'demo01'```

we geht the proper metrics for

```org.apache.cassandra.metrics.ClientRequest.Latency.Read.count```
