Learn about the Wavefront Azure Deployment Manager Integration.

Azure Deployment Manager Integration

The Microsoft Azure Deployment Manager (ADM) service helps you perform staged roll out of resources (global deployment across regions) in an ordered fashion.

While deploying a complex service, ADM lets you deploy resources, orchestrate high-level dependencies, and find potential problems before a service is deployed.

This integration uses the Wavefront REST API for ADM. ADM will invoke the API while executing the health check step as a part of its workflow.

Azure Deployment Manager Setup

This integration uses the Wavefront REST API for ADM. ADM will invoke the API while executing the health check step as a part of its workflow.

Azure Deployment Manager Health Check Configuration Setup

  1. Use the Metrics browser to identify the metric to use as a health metric. Click Browse > Metrics in your Wavefront instance to access the Metrics browser.

  2. Create a query that returns 1 or 0 using the health metric. Example: 
     sum(ts(system.load1)) > 0

  3. Encode the query using an encoder such as dencoder. You’ll use the encoded query below.

  4. In the JSON snippet below, fill in the values for MaxElasticDuration, healthyStateDuration, encoded_query and specify the name of your Wavefront cluster without the .wavefront.com extension. The JSON has pre-populated values for authtoken, uri for health monitor and response code. 
     "properties": {  
    "stepType":"healthCheck",
    "attributes":{  
       "MaxElasticDuration":"",
       "healthyStateDuration":"",
       "type":"REST",
       "properties":{  
          "healthChecks":[  
             {  
                "name":"appHealth",
                "request":{  
                   "method":"GET",
                   "uri":"https://adm.wavefront.com/api/v1/query?c=<cluster_name>&q=<encoded_query>",
                   "authentication":{  
                      "type":"ApiKey",
                      "name":"Authorization",
                      "in":"Header",
                      "value":"YOUR_API_TOKEN"
                   }
                },
                "response":{  
                   "successStatusCodes":[  
                      "200"
                   ]
                }
             }
          ]
       }
    }
 }
  5. Update your ADM rollout template with the updated JSON.

Verification

  1. You can use the curl command to verify the output. For example: 
    curl -X GET --header "Accept: application/json" --header "Authorization: YOUR_API_TOKEN" "https://adm.wavefront.com/api/v1/query?c=<cluster>&q=<encoded_query>"
  2. To fine tune your query, go to the query API. In your Wavefront instance, select API Documentation from the gear icon in the top right and go to the Query API. Then:
  3. Fill in the parameter q with the plain query
  4. Fill in the parameter s with start time in epoch milliseconds
  5. Click on Try it out! button to see the results

Response Codes

  • 200: For query result 1
  • 400: For any query that returns a non boolean value
  • 404: For query result 0
  • 500: Internal Service Error for any query result errors
