Ambari python Client

Ambari python client can be used make use of Ambari APIs.

The first step is to create the Ambari client

from ambari_client.ambari_api import  AmbariClient
client = AmbariClient("localhost", 8080, "admin", "admin", version=1)
print client.version
print client.host_url
print"\n"

Some useful methods

1. Show all clusters in Ambari

   all_clusters = client.get_all_clusters()
   print all_clusters.to_json_dict()
   print all_clusters

2. Show all hosts in Ambari

   all_hosts = client.get_all_hosts()
   print all_hosts
   print all_hosts.to_json_dict()
   print"\n"

Get metrics

1. get cpu-metrics of service component TASKTRACKER

   mr = mycluster.get_service("MAPREDUCE")
   mr_comp1 = mr.get_service_component('TASKTRACKER')
   metric_json = mr_comp1.get_metrics()
   print metric_json["metrics"]["cpu"]
   print"\n"

2. get cpu-metrics from a host which has component NAMENODE

   host1 = mycluster.get_host('host1')
   nn = host1.get_host_component("NAMENODE")
   metric_json = nn.get_metrics()
   print metric_json["metrics"]["cpu"]
   print"\n"
