Enable Application Signals in your account

If you haven't enabled Application Signals in this account yet, you must grant Application Signals the permissions it needs to discover your services. You need to do this only once for your account.

To enable CloudWatch Application Signals, do the following.

  1. Open the CloudWatch console at https://console.amazonaws.cn/cloudwatch/.

  2. In the navigation pane, choose Services.

  3. Choose Start discovering your Services.

  4. Select the check box and choose Start discovering Services.

    Completing this step for the first time in your account creates the AWSServiceRoleForCloudWatchApplicationSignals service-linked role. This role grants Application Signals the following permissions:

    • xray:GetServiceGraph

    • logs:StartQuery

    • logs:GetQueryResults

    • cloudwatch:GetMetricData

    • cloudwatch:ListMetrics

    • tag:GetResources
