This MIB module defines textual conventions used by the MIB modules defining objects describing flow monitoring. GLOSSARY ============ Alarm Action - a method used by the device to signal changes in an alarm condition. Alarm Aggregation - a technique used to efficiently monitor the same standing condition for a flow set. Alarm Condition - a standing condition for which the device signals changes in state. Alarm Group - a flow set for which the device monitors a configured standing condition, raising an alarm when a configured number of flows in the flow set assert the standing standing. Alarm Severity - the relative disposition of an alarm condition when raised by the device. For example, a provider may regard a flow stop alarm as having a higher severity than a flow's loss fraction exceeding a configured threshold. Flow Monitor - a hardware or software entity that classifies traffic flows, collects flow data, and periodically computes flow metrics. Flow Metric - a measurement that reflects the quality of a traffic flow. Flow Point - represents the ingress or egress of a traffic flow. Flow Set - a group of traffic flows. Measurement Interval - the length of time over which a flow monitor collects data related to a traffic flow, after which the flow monitor computes flow metrics using the collected data. Standing Condition - represents a lasting error, fault, or warning resulting from the application of a set of criteria to the state of an entity, such as a flow monitor or traffic flow. For example, a flow monitor may assert a standing condition if the number of traffic flows that expire in a meansurement interval exceeds a configured threshold. Traffic Flow - a unidirectional stream of packets conforming to a classifier. For example, packets having a particular source IP address, destination IP address, protocol type, source port number, and destination port number.
