> #### Problem definition

> The XYZ Corporation's system administrator was having a routine, mid-week work day. Normal system processing was occurring as the system was humming along just fine. Response time was good, and his users were very pleased. There's always room for improvement, but at the moment, the monitoring results showed no cause for concern.

> Unexpectedly, however, the system's performance began to decline rapidly. The system administrator's phone began to ring off the hook with end-user calls. The complaints were all the same: transactions were not going through, and data entry tasks could not be completed. Even simple look-up activities failed.
