Table 90 Alarm Group Configuration controls
Control
Description
Alarm Group ID
Configures the numeric identifier of the Alarm index.
MIB Object ID
Configures an alarm MIB Object Identifier.
The alarm OID can have a maximum of 127 characters.
Rising Limit
Configures the rising threshold for the sampled statistic. When the current sampled value is
greater than or equal to this threshold, and the value at the last sampling interval was less than
this threshold, a single event is generated.
Falling Limit
Configures the falling threshold for the sampled statistic. When the current sampled value is
less than or equal to this threshold, and the value at the last sampling interval was greater than
this threshold, a single event is generated.
Rising Event Index
Configures the rising alarm event index that is triggered when a rising threshold is crossed.
The range is from 0 to 65535. The default value is 0.
Falling Event Index
Configures the falling alarm event index that is triggered when a falling threshold is crossed.
The range is from 0 to 65535. The default value is 0.
Alarm Type
Configures the alarm type as rising, falling, or either (rising or falling).
Sample Type
Configures the method of sampling the selected variable and calculating the value to be
compared against the thresholds, as follows:
abs: absolute value, the value of the selected variable is compared directly with the
thresholds at the end of the sampling interval.
delta: delta value, the value of the selected variable at the last sample is subtracted from
the current value, and the difference compared with the thresholds.
Polling Interval
Configures the time interval over which data is sampled and compared with the rising and
falling thresholds.
The range is from 1 to 3600 seconds. The default is 1800 seconds.
Owner
Enter a text string that identifies the person or entity that uses this alarm index.
The owner can have a maximum of 127 characters.
