1. Global Alert Types
- Fixed Value: This will compare the latest measurement value to a specific threshold that you set
- Prior Value: Compare the latest measurement value to a prior value for the same metric (e.g. value from same time last year)
- Average of prior values: Compare the latest measurement value to the average of values recorded recently
- Recent Volatility Levels: Compare the latest measurement value to the standard deviations of the average of values recorded recently
- Stoplight: By applying this type of alert Rule to a Metric, you activate its Stoplight View. Refer to: Define a Metric's Stoplight
- Unusual / Best / Worst Value: The Unusual value is determined by setting of Statistical View (# of standard Deviations) in Metric Editor > Charting tab and do not require defining criteria to the Alert Rule itself.
Modifying these settings will change the circumstances under which the Metric fall within the Stoplight is red value.
NOTE: Based on screen above, the data value would have to fall below 5% of Target twice after having been above 5% at least one time.
Unusual alerts are triggered when a value falls outside of Statistical range set individually for each Metric. This value is set in the Charting tab of the Metric Editor; the default is 2 Standard Deviations. The alerts generated will be labeled as either an Unusual Low or Unusual High.
2. Alert Criteria
This step is going to have different set of Alert criteria options depending on the Alert Rule Type selected in Step 1 (see above).
Unusual / Best / Worst Value Alert rules do not require defining criteria.
