Statistical Parameter

Use aggregation statistical parameters to do more with your data. The statistical parameters are calculated in the cloud based on the underlying parameter reported by the Aethair device. Statistical parameters do not affect the underlying collected data, and you can add and remove them as needed.

For example, use the Average value of a parameter over a time period to smooth out spikes or extreme values. Set alarms based on this statistic instead of an instantaneous value to avoid false positives. These are also useful for applications such as monitoring permissible exposure limits for a work shift of 8 hours.

Minimum (MIN): Returns the minimum value over the rolling time period.
​Maximum (MAX): Returns the maximum value over the rolling time period.
​Average (AVG): Returns the average over the rolling time period (moving average).

All statistical parameters use a rolling (moving) window. The parameter is still reported at the device's normal reporting interval, the time period does not change how often values are reported, only what each value represents.
​

For example, a 15-minute Average parameter on a device reporting every minute produces a new value every minute, and each value is the average of the previous 15 minutes of measurements. It does not produce one value every 15 minutes.
​

Choose a time period between 5 minutes and 1 month for the Min, Max and Average functions. The available intervals are:

Alerts use the same rolling-average behavior. An alert condition on a 15-minute average is evaluated against the rolling average at each reporting interval, just like a statistical parameter. See Referencing Devices in Alerts.

For time periods up to 2 hours, a new rolling value is calculated at every device report.
