Metric Levels

There's different levels of metrics, including cluster, host, component, and host-component.

Cluster Level Metrics

Ambari API

https://<Ambari_Server_IP>:<port>/api/v1/clusters/<cluster-name>?fields=metrics[startTime,endTime,Interval]

Example:

https://<Ambari_Server_IP>:<port>/api/v1/clusters/<cluster-name>?fields=metrics/cpu[1683808200,1683808260,15]&_=1430848532905

Where &_=1430848532905 doesn't effect the response used to bypass caching.

Host Level Metrics

Ambari API

https://<Ambari_Server_IP>:<port>/api/v1/clusters/<cluster-name>/hosts/<host-name>?fields=metric1[startTime,endTime,Interval],metric2[startTime,endTime,Interval]

Example:

https://<Ambari_Server_IP>:<port>/api/v1/clusters/<cluster-name>/hosts/<host-name>fields=metrics/cpu/cpu_user[1683808200,1683808260,15],metrics/cpu/cpu_wio[1683808200,1683808260,15],metrics/cpu/cpu_nice[1683808200,1683808260,15],metrics/cpu/cpu_aidle[1683808200,1683808260,15],metrics/cpu/cpu_system[1683808200,1683808260,15],metrics/cpu/cpu_idle[1683808200,1683808260,15]&_=1430848217591

Component Level Metrics

Ambari API

http://<AMC_IP>:<port>/ws/v1/timeline/metrics?metricNames=cpu_user,cpu_wio,cpu_nice,cpu_aidle,cpu_system,cpu_idle&hostname=<host-name>&appId=HOST&startTime=1683808200&endTime=1683808260&interval=15000

Example:

https://<Ambari_Server_IP>:<port>/api/v1/clusters/metric01nh/services/HDFS/components/ DATANODE?fields=metrics/dfs/datanode/DfsUsed,metrics/dfs/datanode/Capacity&_=1430849798630

Host-Component Level Metrics

Ambari API

https://<Ambari_Server_IP>:<port>/api/v1/clusters/<clusterName>/hosts/<host-name>/host_components/DATANODE?fields=metric1,metric2 (point query)

Example:

https://<Ambari_Server_IP>:<port>/api/v1/clusters/<clusterName>/hosts/<host-name>/host_components/DATANODE?fields=metrics/disk/disk_free,metrics/disk/disk_total
