Alarm Types
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.
