ambari rest api for ambari metrics

I am using rest api for getting ambari metrics what AMS displays at ambari Dashboard .

curl -v "http://<metrics_host>:6188/ws/v1/timeline/metrics?metricNames=master.Server.numDeadRegionServers&hostname=&appId=HOST&instanceId=&startTime=1451630974&endTime=1519110315"

but above rest api does not fetch any result.

Please refer below link for all metrics :

In your Query looks like there is some special character. it works for me:

Example:

# curl -v "http://amb25102.example.com:6188/ws/v1/timeline/metrics?metricNames=master.Server.numDeadRegionServers&hostname=%&appId=hbase&instanceId=&startTime=1451630974&endTime=1519110315"

.

Example Output:

# curl -v "http://amb25102.example.com:6188/ws/v1/timeline/metrics?metricNames=master.Server.numDeadRegionServers&hostname=%&appId=hbase&instanceId=&startTime=1451630974&endTime=1519110315"

Also the "appId" should be hbase instead of HOST.
