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).
