Event Property

Statsig enables you to breakdown metrics into a single set of non-overlapping dimensions for deep dive analyses.

For example, you can breakdown an event such as add-to-cart into product categories such as sports, toys, appliances, electronics. To do this, you would simply log add-to-cart events and provide the product category in the event's value field. See the Statsig SDK reference guide to learn more.

Statsig enables you to define up to four custom dimensions for an event (one via the value field and three via metadata fields). To configure these custom event fields, go to Metrics --> Events, select the event you want to configure, and then go to the Setup tab for that event.

Providing custom dimensions with logged events allows you to break down the impact on the total add-to-cart events by category in Pulse as shown below. This enables you to zero in on the category that's most impacted by your experiment.

Statsig recommends keeping the number of distinct dimensions in your logging less than 8. This is because tracking dimensions involves additional computational and storage resources, so we prioritize notable dimensions that make up a significant portion of your traffic. As a rule of thumb, we track dimensions that make up >5% of your total event volume. We don't track lower frequency dimensions since they generally have larger degrees of statistical noise and wider confidence intervals. We will bucket them in an "Other" bucket.

Statsig also supports metric dimensions for custom metrics that are Aggregations. To set this up, log your dimension as a value and the number to be tallied as a metadata field.

This is the old metric dimension page. We renamed it to Event Property.
