The History Control table stores configuration entries containing the interface information, polling period, number of buckets requested, and number of buckets granted. The number of buckets requested represents the number of times the operator wants to collect and store the samples. The probe will respond with the number of buckets granted based on the requests as well as available resources.

At each sampling cycle, the following statistics are collected and stored:

Utilization

All of the above are also gathered by the Statistics MIB with the exception of utilization. For an explanation of the individual statistics, please refer to 10.4.1.1, ªStatistics Groupº on page 196.

The utilization statistics give the Ethernet physical layer network utilization during the specified time interval, in hundredths of a percent.

10.4.1.3 Alarm Group

The Alarm group is used to track extraordinary activities or events. It permits the operator to set the RMON alarms to specific thresholds, and when traffic exceeds or drops below those thresholds, an event is activated. Thresholds can be defined as a rising threshold or a falling threshold.

A rising threshold is used to monitor the value of a tracked variable when it rises above a particular level. For instance, you might want to set a rising threshold for the occurrences of error packets at 200 packets/second. If the error packet rate exceeds 200 packets/sec, the rising threshold is exceeded and an event will be generated.

A falling threshold is used to report an event when the value of a tracked variable has fallen below a particular threshold level.

Thresholds can be set against either absolute or delta values. If an absolute value is chosen, the absolute value stored in the variable ′s counter will be compared directly with the absolute threshold value. For delta values, the value of the selected variable at the last sample is subtracted from the current value, and the difference is compared with the threshold value.
