This add-on monitors the queue size of the TrendHistorianService over time. Data points are recorded every 15 seconds and are stored for 3 days. When the queue size surpasses 2500, email notification alarms can be configured. A deadband of 15% is used to prevent spurious notifications. You can view a graph of queue size over time from the add-on's main page. Hold CTRL or SHIFT while navigating the graph to lock your cursor to the nearest data point. If you enter a visible timespan in minutes and press ENTER, the graph will reload to show the specified data.
