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,

mode. For metric service to work in HA mode
timeline.metrics.service.webapp.address cannot be changed to hostname as we
So from where can we get active metric collector hostname?
