Fiddler supports some simple statistic metrics which can be used to monitor basic aggregations over Columns.

These can be particularly useful when you have a custom metadata field which you would like to monitor over time in addition to Fiddler's other out-of-the-box metrics.

Specifically, we support

  • Average (takes the arithmetic mean of a numeric column)
  • Sum (calculates the sum of a numeric column)
  • Frequency (shows the count of occurrences for each value in a categorical or boolean column)

These metrics can be accessed in Charts and Alerts by selecting the Statistic Metric Type.

Frequency Metric Alerting

Currently, alerts cannot be set on the Frequency Metric. Support for this will be added in a future release.
