What to do next

  • Verify that the recommendations resolve the alert. Run a few collection cycles after you run the action and verify that the alert is canceled. Alerts are canceled when the conditions that generated them are no longer true.

  • Implement the other recommendations. The other recommendations for this alert require you to use other applications. You cannot implement the recommendations from vRealize Operations Manager.
