General Troubleshooting for System Center 2012 — Operations Manager

Try the following to resolve any issues.

  • Verify that you have installed the latest Update Rollup for System Center 2012 — Operations Manager. The AWS Management Pack requires at least Update Rollup 1.

  • Ensure that you have configured the AWS Management Pack after importing it by running the Add Monitoring Wizard. For more information, see Step 1: Installing the AWS Management Pack.

  • Verify that you have waited long enough for the AWS resources to be discovered (10–20 minutes).

  • Verify that the management servers are configured properly.

    • Management servers must have Internet connectivity.

    • The action account for a management server must have local administrator privileges on the management server.

    • The management server must have the .NET Framework 4.5. or later.

  • Verify that the AWS Run As account is valid.

    • The values for the access key ID and secret access key are correct.

    • The access keys are active: In the AWS Management Console, click your name in the navigation bar and then click Security Credentials.

    • The IAM user has at least read-only access permission. Note that read-only access allows the user actions that do not change the state of a resource, such as monitoring, but do not allow the user actions like launching or stopping an instance.

      • If an Amazon CloudWatch metric shows as Not Monitored, check whether at least one Amazon CloudWatch alarm has been defined for that Amazon CloudWatch metric.
