For (Minutes) is one of the required fields when setting any alert. vAnalytics Real Time is constantly retrieving status information and activity data from your monitored UC environment, and typically receives updates every 15 seconds for every dimension which can be set for Alerts.
Brief anomalies are a reality in even the best-performing environments, so the For (Minutes) field sets the continuous fault duration required to trigger an alert. The minimum setting is 1 minute, meaning 4 consecutive measurements of the monitored value would have to be at or beyond the alert threshold before the alert will be sent. (2 minutes = 8 consecutive alert level values, 5 minutes = 20 consecutive alert level values, etc.)
If the value returns to a normal range before the alert is triggered, then the duration “counter” is reset, and any subsequent alert level reading would again be subject to the full continuous fault duration once again.
