Alarm group list
• Index: Contains unique index values for the associated alarm.
• Item: Contains the metric that is measured by this alarm instance.
• Port: Contains the port name/description for the associated interface.
• Sampling Type: Identifies whether or not the value of the sample to be measured should be
evaluated in an absolute sense or in a comparative sense. Absolute sampling measures the current
sampling value accumulated since the system started up. Comparative sampling, also referred to as
delta sampling, measures the value by subtracting the last absolute sampling value from the current
absolute sampling value. The sampling interval is also a factor in comparative or delta sampling.
Generally, delta or comparative sampling is selected.
• Interval (second): Contains the amount, in seconds, of time between polls.
• Current Sampling Value: Contains the value for the most recent sample.
• Startup Type: Contains the type of threshold being used by the alarm instance. Three alarm startup
types are available: allowing rising and falling alarms, allowing rising alarms and allowing falling
alarms.
• Rising Threshold: Contains the rising threshold value. A rising threshold defines the value that the
sampled value must exceed in order to generate an alarm.
• Falling Threshold: Contains the falling threshold value. A falling threshold defines the value that the
sampled value must fall below in order to generate an alarm.
• Rising Event Index: Contains the index for a rising event.
• Falling Event Index: Contains the index for a falling event.
• Owner: Contains the name of the owner of the RMON statistics collection that is configured when
you add the interface to Alarm Group collection.
• Status: Indicates whether or not the alarm instance is active.
• Reason for Null: Contains the cause for the null value for the associated alarm group entry.
