title: CsvReporter not spitting out metrics in cassandra
body: <p>I have added the following file on my cassandra node</p>
  
  <p>/etc/dse/cassandra/metrics-reporter-config.yaml</p>
  
  <pre><code>csv:
    -
      outdir: '/mnt/cassandra/metrics'
      period: 10
      timeunit: 'SECONDS'
      predicate:
        color: "white"
        useQualifiedName: true
        patterns:
          - "^org.apache.cassandra.metrics.Cache.+"
          - "^org.apache.cassandra.metrics.ClientRequest.+"
          - "^org.apache.cassandra.metrics.CommitLog.+"
          - "^org.apache.cassandra.metrics.Compaction.+"
          - "^org.apache.cassandra.metrics.DroppedMetrics.+"
          - "^org.apache.cassandra.metrics.ReadRepair.+"
          - "^org.apache.cassandra.metrics.Storage.+"
          - "^org.apache.cassandra.metrics.ThreadPools.+"
          - "^org.apache.cassandra.metrics.ColumnFamily.+"
          - "^org.apache.cassandra.metrics.Streaming.+"
  </code></pre>
  
  <p>And then added this line to etc/dse/cassandra/cassandra-env.sh</p>
  
  <pre><code> ​JVM_OPTS="$JVM_OPTS -Dcassandra.metricsReporterConfigFile=metrics-reporter-config.yam"
  </code></pre>
  
  <p>And then finally restarted DSE, /etc/init.d/dse restart</p>
  
  <p>I dont see any csv metrics files being spitted out by the MetricsReported in /mnt/cassandra/metrics folder.</p>
  
  <p>any  ideas why?</p>
