Confidence-based alerts
Confidence is a measure of how certain we are about the detected change in selected
statistics of data. Setting the range of confidence will alert you if the detected
change is within the set confidence level.
Important:
- The scale can only be set from 20% to 100%.
- The range below 20% is a very low confidence level and generates a lot of noise in your alerts.
For example, the confidence-based alerts set between 60% and
80% will send alerts only when the confidence of change in selected statistics of
data is detected between 60% and 80%. The alert will be a critical alert when the
change is detected for a confidence level above 80%.
Note:
- The alerts will not be generated for lower values if the percentage
overlap, the alerts will be generated only for values beyond the higher
range.
- For example, alerts will not be generated below 80% for the range selected as 80% to 80%. Alerts will be generated only above 80%.
- It will set to a default range if your range overlaps at 100%.
- For example, if you set the range as 100% to 100%, the range will revert to default range as 60% to 80%.
