AppDynamics Golden Signal

To create a Service, you must add at least one Golden Signal monitor to your Service definition. Gremlin recommends a combination of 3 to 5 monitors for a well-rounded view of your Service’s health. Once you have selected a Service type, defined its fingerprint, and selected a process, you'll be able to start adding Golden Signal monitors to your Service.

Adding an AppDynamics Golden Signal Monitor

The Application URL must point to an Application entity relevant to the Service you are creating in Gremlin. You can get this from the Applications tab in the AppDynamics web app. See Alert and Respond in the AppDynamics documentation for more information.

To add an AppDynamics Golden Signal:

• Select AppDynamics from the Integrations drop-down and click Add.

• If the AppDynamics integration has been authenticated in Team Settings, you will only see the Application URL box — in this case, continue to the next step. If the API key and application key have not been defined for the team, you'll also see the Authentication and Headers section — in this case, you'll need to set up the AppDynamics team integration first.

  

• In the AppDynamics web app, navigate to the Applications tab and select your app.

• Back in the Gremlin web app, update the base Application URL to include the Application ID. For example: https://example.saas.appdynamics.com/controller/#/location=APP_DASHBOARD&timeRange=last_1_hour.BEFORE_NOW.-1.-1.60&application=1042798&dashboardMode=force

• Click Test Golden Signal.  Gremlin will query /problems/healthrule-violations AppDynamics API for existing health-rule violations, using the application entity ID from the input URL.

  • If the monitor is OK, the response will look similar to this:

  

  • If the monitor is in another state like Alert, Ignored, No Data, Skipped, Unknown, or Warn, you can still save the Golden Signal, but it will not evaluate to successful once a Reliability Test is run, impacting the Service's Reliability Score.

• Click Save.

Editing a Golden Signal Monitor

To edit a Golden Signal Monitor, go to the specific Service, click Settings, and then click the Golden Signals tab.
