UTL:
Utilization

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).

Format:

A:mm/dd/yyyy hh:mm:ss

UTL:ALRT|NMRL:CPU|CON|CPS:/*message*/

Where:

A: identifies the message as an alarm.

mm/dd/yyyy hh:mm:ss is the timestamp.

UTL: identifies the message as an Utilization

Threshold Alarm.

Alarm Modifiers and Messages

ALRT: Message: [CPU|Open connections|CPS] exceed

high water mark

NMRL: Message: [CPU|Open connections|CPS] drop

below low water mark
