Aggregated value analysis
As an alternative to monitoring live values, alarm conditions can be defined on the basis of recorded values. For example, the daily total can be calculated at the end of each day and an alert can be triggered if it is exceeded or undercut.
Configuration
Mode | Choose whether the average, the sum, the minimum or the maximum value should be determined for the monitoring. |
Interval | Determine the interval at which the historical values are to be aggregated and monitored. |
Threshold profile
Different threshold values can be defined via a threshold profile, depending on the time of day, day of the week, month or quarter. Click on Edit threshold profile and choose an Interval first.
Use the Tolerance value to determine the permissible deviation from the threshold value as a percentage.
If individual threshold values are not specified, there will be no monitoring at these intervals. For example, the threshold values for Saturday and Sunday can be left blank to prevent the alert from being triggered at the weekend.
Tip: With the Determine from data function, the threshold values are calculated from recorded values and can then be adjusted.
