For example, a simulation that includes a server with an impact state of Unavailable might return several related CIs that are predicted to be unavailable as a result of the unavailable server. When you run a simulation, BMC Atrium Impact Simulator uses these states and the impact relationships defined between CIs to predict the corresponding impact on the items that the CIs represent.
The item has a failure and is unable to deliver any service. The item's delivery of service is affected. The item's delivery of service is slightly affected. The item is delivering services normally, but some problem might affect it.
