Hi Saloni,

When you have multiple metrics collectors all of them are active. Any one of them can be used.

FYI, there are 3 lookup options for the list of collectors.

  *   Ambari Cluster Host info.
  *   Zookeeper znode path (/ambari-metrics-cluster/LIVEINSTANCES)
  *   Response to http://<ANY_COLLECTOR_HOST>:6188/ws/v1/timeline/metrics/livenodes

Thanks and Regards,

    We have developed a custom script based alert for our ambari service which

    timeline.metrics.service.webapp.address cannot be changed to hostname as we

    previously did.

    So from where can we get active metric collector hostname?
