UTL: Utilization Threshold Alarm

This alarm monitors three utilization threshold values:

•CPU

•Connections per Second

•Total Open Connections.

When enabled, an alarm is issued whenever any of the utilization values exceeds its high-water mark, or, having exceeded the high- water mark, drops below the low-water mark. The user defines the high and low-water marks. By default, the high-water mark is 90% and the low-water mark is 60%.

The data collected for utilization threshold metrics tends to be bursty, so a smoothing algorithm is used to prevent continuous alarms.The utilization window is a user-specified sliding interval during which data is collected and averaged. Consequently, shorter intervals are likely to result in some extraneous alarms. The interval can be set from 5 to 65000 seconds (default: 15).
