Verify Deployments with Dynatrace

Updated 1 month ago by Renu Bhaskaran

Harness CV integrates with Dynatrace to:

  • Verify that the deployed service is running safely and performing automatic rollbacks.
  • Apply machine learning to every deployment to identify and flag anomalies in future deployments.

This topic covers how to add and configure Dynatrace as a Health Source for the Verify step.

Add Dynatrace as a verification provider

Review: CV Setup Options

To use the Verify step, you will need a Harness Service Reliability Management Monitored Service. In the simplest terms a Harness Monitored Service is a Service and Environment combination, that Harness monitors for:

  • Any changes, such as deployments, infrastructure changes, and incidents
  • Any health trend deviations using logs and metrics obtained from APM and Logging tools respectively

No matter where you set up the Monitored Service, once it's set up, it's available to both Service Reliability Management and CD modules.

In this topic, we set up the Harness Monitored Service as part of the Verify step setup.

Step 1: Add Verify Step

There are two ways to add the Verify step:

  • When selecting the stage deployment strategy:
    The Verify step can be enabled in a CD stage the first time you open the Execution settings and select the deployment strategy. When you select the deployment strategy you want to use, there is also an Enable Verification option. Select the Enable Verification option.
    Harness will automatically add the Verify step. For example, here is a stage where Canary strategy and the Enable Verification option were selected.
  • Add the Verify step to an existing Execution setup: You can also add the Verify step to the Execution section of a CD stage in a Pipeline you previously created. Simply click Add Step after the deployment step, and then select Verify.

Step 2: Enter a Name and Timeout

In Name, enter a name for the step.

In Timeout, enter a timeout value for the step.

You can use:

  • w for weeks
  • d for days
  • h for hours
  • m for minutes
  • s for seconds
  • ms for milliseconds

The maximum is 53w.Timeouts can be set at the Pipeline level also.

Step 3: Select a Continuous Verification Type

In Continuous Verification Type, select a type that matches your deployment strategy.

Step 4: Create a Monitored Service

In Monitored Service, click Click to autocreate a monitored service.

Harness automatically creates a Monitored Service using a concatenation of the Service and Environment names. For example, a Service named todolist and an Environment named dev will result in a Monitored Service named todolist_dev.

If the stage Service or Environment settings are Runtime Inputs, the Monitored Service and Health Sources settings will show up in the Runtime Input settings when you run the Pipeline.

Step 5: Add Health Sources

A Health Source is basically a mapping of a Harness Monitored Service to the Service in a deployment environment monitored by an APM or logging tool.

In Health Sources, click Add. The Add New Health Source settings appear.

  1. In Select health source type, select Dynatrace.
  2. In Health Source Name, enter a name for the Health Source. For example Quickstart.
  3. Under Connect Health Source, click Select Connector.
  4. In Connector settings, you can either choose an existing connector or click New Connector to create a new Connector.
  5. After selecting the connector, click Apply Selected. The Connector is added to the Health Source.
  6. In Select Feature, a Dynatrace feature is selected by default.
  7. Click Next. The Customize Health Source settings appear.
The subsequent steps in Customize Health Source depend on the Health Source type you selected. 
  1. In Find a Dynatrace service, enter the name of the desired Dynatrace service.
  2. In Select Metric Packs to be monitored, you can select Infrastructure or Performance or both.
  3. Click Add Metric if you want to add any specific metric to be monitored (optional) or simply click Submit.
  4. If you click Add Metric, click Map Metric(s) to Harness Services.
  5. In Metric Name, enter the name of the metric.
  6. In Group Name, enter the group name of the metric.
  7. Click Query Specifications and mapping.
  8. In Metric, choose the desired metric from the list.
  9. Click Fetch Records to retrieve data for the provided query.
  10. In Assign, choose the services for which you want to apply the metric. Available options are:
    • Continuous Verification
    • Health Score
    • SLI
  11. In Risk Category, select a risk type.
  12. In Deviation Compared to Baseline, select one of the options based on the selected risk type.

Click Submit. The Health Source is displayed in the Verify step.

You can add one or more Health Sources for each APM or logging provider.

Step 6: Select Sensitivity

In Sensitivity, select High, Medium, or Low based on the risk level used as failure criteria during the deployment.

Step 7: Select Duration

Select how long you want Harness to analyze and monitor the logs/APM data points. Harness waits for 2-3 minutes to allow enough time for the data to be sent to the APM/logging tool before it analyzes the data. This wait time is a standard with monitoring tools.

The recommended Duration is 10 min for logging providers and 15 min for APM and infrastructure providers.

Step 8: Specify Artifact Tag

In Artifact Tag, use a Harness expression to reference the artifact in the stage Service settings.

The expression <+serviceConfig.artifacts.primary.tag> refers to the primary artifact.

Option: Advanced Settings

In Advanced, you can select the following options:

See Advanced Settings.

Step 9: Deploy and Review Results

When you are done setting up the Verify step, click Apply Changes.

Now you can run the Pipeline. Click Run.

In Run Pipeline, select the tag for the artifact if a tag was not added in the Artifact Details settings.

Click Run Pipeline.

When the Pipeline is running, click the Verify step.

The verification takes a few minutes.

The risk level might initially display a number of violations, but often changes over the duration.

Summary

The Summary section shows the number of metrics that are in violation.

Click Console View or simply click View Details in Summary to take a deeper look at verification.

If you have more than one Health Source, you can use the Health Source dropdown to select each one.
