Updated ambari-metrics-collector mode to distributed and No Metrics is available

New Contributor

I have updated existing cluster ambari-metrics-collector to distributed mode. As reference, I followed

https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.2.0/bk_ambari-operations/content/ams_metrics_co...

And I have added one more metrics collector in the cluster. Both, metrics collector are up and running but still no metrics available.

Below are the logs where host are setting as null ( not sure why).
