Create Ambari alert from kafka ambari metric

[#1]

I am able to get a metric from ambari using the following request:

curl -u  *****:**** -H "X-Requested-by:ambari" -i -k -X GET http://server:6188/ws/v1/timeline/metrics?metricNames=kafka.server.BrokerTopicMetrics.MessagesInPerS...

How can I create a alert on this metric? I have read https://community.hortonworks.com/questions/39457/kafka-custom-alert-with-ambari-222.html which requires a python script. How can I nativly use the metrics from ambari/grafana to create a alert.

I believe this doc contains the information you're looking for: https://github.com/apache/ambari/blob/branch-2.1/ambari-server/docs/api/v1/alert-definitions.md#metr...

METRIC

METRIC source fields are used to define JMX endpoints that can be queried for values. The source/reporting and jmx/value fields are parameterized to match the property_list specified.

    "source" : {
      "jmx" : {
        "property_list" : [
          "java.lang:type=OperatingSystem/SystemCpuLoad",
          "java.lang:type=OperatingSystem/AvailableProcessors"
        ],
        "value" : "{0} * 100"
      },
      "reporting" : {
        "ok" : {
          "text" : "{1} CPU, load {0:.1%}"
        },
        "warning" : {
          "text" : "{1} CPU, load {0:.1%}",
          "value" : 200.0
        },
        "critical" : {
          "text" : "{1} CPU, load {0:.1%}",
          "value" : 250.0
        },
        "units" : "%"
      },
      "type" : "METRIC",
      "uri" : {
        "http" : "{{hdfs-site/dfs.namenode.http-address}}",
        "https" : "{{hdfs-site/dfs.namenode.https-address}}",
        "https_property" : "{{hdfs-site/dfs.http.policy}}",
        "https_property_value" : "HTTPS_ONLY",
        "default_port" : 0.0,
        "high_availability" : {
          "nameservice" : "{{hdfs-site/dfs.nameservices}}",
          "alias_key" : "{{hdfs-site/dfs.ha.namenodes.{{ha-nameservice}}}}",
          "http_pattern" : "{{hdfs-site/dfs.namenode.http-address.{{ha-nameservice}}.{{alias}}}}",
          "https_pattern" : "{{hdfs-site/dfs.namenode.https-address.{{ha-nameservice}}.{{alias}}}}"
        }
      }
    }
