Want to check, how it can be achieved.

Answer 1

You can control all of the metrics reporting options in the server yaml file under metrics. Essentially:

metrics: {
  consoleReporter: {enabled: false, interval: 180000},
  csvReporter: {enabled: false, interval: 180000, fileName: /tmp/gremlin-server-metrics.csv},
  jmxReporter: {enabled: false},
  slf4jReporter: {enabled: false, interval: 180000}}
}

In the example above I just set enabled to false for all of them, but you could obviously be more selective in how you choose to do that.
