As the AMS collector seems to be running it should collect and show the data however we will need to check if AMS collector has the data or not? So in order to check that we will need to capture the following informations:

1. Need to make an API call to the AMS collector in order to list down the number & names of metrics that it is collecting? and from which hosts. The following URLs will give us JSON output . Can you please share the same here.

http://<ams-host>:6188/ws/v1/timeline/metrics/metadata
http://<ams-host>:6188/ws/v1/timeline/metrics/hosts

2. Need to check the Binaries of ambari collector and sink (so that we can see if it is same as ambari ersion)

# rpm -qa | grep ambari 

3. Can you please check if the metrics-monitor logs shows any kind of connectivity error while connecting to AMS collector?

# /var/log/ambari-metrics-monitor/ambari-metrics-monitor.out 

4. Do we see if the hostname resolution if file and correctly defined inside the "/etc/ambari-metrics-monitor/conf/metric_monitor.ini" file

5. Please check if the AMS collector log shows any error?
