  "config": {
      "producer.interceptor.classes": "io.confluent.monitoring.clients.interceptor.MonitoringProducerInterceptor",
      "connector.class": "org.cmatta.kafka.connect.irc.IrcSourceConnector",
      "irc.server": "irc.wikimedia.org",
      "kafka.topic": "wikipedia.raw",
      "irc.channels": "#en.wikipedia,#en.wiktionary,#en.wikibooks,#en.wikinews,#es.wikipedia,#fr.wikipedia",
