Segmentation

When a segmentation field is selected, the metric monitor will calculate metrics grouped by the values in that field. This helps to isolate and "louden" anomalies that could otherwise be diluted and missed. Common fields to segment by include products, regions, event types, versions, sources, and merchants.

Up to two segmentation fields can be selected in a single monitor. If two segmentation fields are chosen, the monitor will calculate metrics grouped by each combination of values from those multiple fields, e.g. product = 'Loans' AND region = 'EMEA'. If product has 25 distinct values and region has 5 distinct values, that would be 125 segments (25 * 5 = 125).

The maximum number of segments per monitor depends on how it is configured:

• Up to 10,000 segments can be tracked if a single metric is selected and it is scheduled to run daily
• Up to 1,000 segments can be tracked if multiple metrics are selected and it is scheduled to run more frequently than once per day

When adding a segmentation field, the user is required to click Test. This will check how many segments are present.

If an already configured monitor exceeds the maximum number of allowable segments, the monitor will fail to execute, and the appropriate audiences will be sent a notification about the failure.
