1. Friendly name : name of alert

2. Site : select the site for which an alert will be set

3. Source : select a source for which an alert will be set

4. Variable : select the variable linked to the source for which an alert will be set

5. Treshold:

5.1. Low: the alert will apply if the value of the data received is lower than the value

5.2. High: the alert will apply if the value of the data received is higher than the value

6. Value: value which determines the threshold value

7. Type of alert:

7.1. Raw: each time a data point is received, the system will verify if the value of the data point is lower or higher (threshold) than the threshold value

7.2. Rolling: the verification period is based on a rolling time schedule. Each time a data point is received, the system will verify if a data point, within a specific period defined by “Granularity”, is higher or lower than the threshold value. If in one period specified, more data points are available, the data is aggregated based on your choice at “Aggregated”.

7.3. Scheduled: the verification period is being defined by two parameters: “Interval” and “Next execution”

8. Granularity: time period for which data will be verified. If in one period specified, more data points are available, the data is aggregated based on your choice at “Aggregated”.

9. Aggregation: if, in the time period defined at “Granularity” more than one data points are received, the data points will be aggregated based on you choice:

9.1. AVG: average value of the data points

9.2. Count: count the number of data points

9.3. MAX: maximum value of data points out of all values of all data points

9.4. MIN: minimum value of data points out of all values of all data points

9.5. STDEV: standard deviation

9.6. Sum: sum of all values of all data points

9.7. VAR; variance

10. Interval: period of time between the the next execution and the one execution after the next one

11. Next execution: date of next execution (in order to fix a starting date)
