How is the average of condition controls calculated?

Last changed in 02/09/2024

When inserting monitoring values, the moving average is calculated for that value considering the average window defined in the monitoring and the average window value used on the calculation is also saved. It is performed for the next N-1 values (in the most recent date), and N is the average window value defined on the monitoring.

Example

The calculation of the average for a value is that value's sum with the previous N-1 values (in the oldest date) dividing by N, and N is the average window value defined on the monitoring.

Value	Date	Average	Average window
2	15/07/2020 9:00:00
7	13/07/2020 9:00:00	5,67
6	10/07/2020 9:00:00	6
4	07/07/2020 9:00:00	5,67
8	06/07/2020 9:00:00
5	03/07/2020 9:00:00
10	01/07/2020 9:00:00

After inserting the value 4 for the day 07/07/2020 we remain with the following values:

Average window: 3
The value 4 is inserted in a date between the values 8 and 6: 10, 5, 8, 4, 6, 7, 2
The calculation of the average for the value 4 is: (4 + 8 + 5) / 3 = 5,67
The calculation of the average for the value 6 is updated to: (6 + 4 + 8) / 3 = 6
The calculation of the average for the value 7 is updated to: (7 + 6 + 4) / 3 = 5,67
