This object holds the sampling interval type (such as a 5-minute, 15-minute, or daily period) used when evaluating a configured threshold against a flow's monitored performance variable. Knowing this interval matters because it tells the admin how frequently the flow's counter is checked against the threshold value, which affects how quickly a threshold-crossing alert can fire after a real problem starts. For instance, an admin troubleshooting a flow-level SLA might set cmFlowThresholdInterval to a 5-minute period so that a sudden burst of drops triggers a threshold alarm within minutes rather than waiting for a full day's bin to close.
