Transformations Observability

The Events tab of your transformation displays volume metrics for all ingested events, including transformation errors. This is helpful in understanding how the transformed events are flowing through and taking any remedial actions in case of errors.

Transformations event metrics

In this section, you get the following event metrics for your transformation:

• Events ingested: Number of events ingested by the RudderStack source.
• Events filtered: Number of events intentionally dropped or filtered by the transformation. For example, if your transformation allowlists only track events with the name Product Purchased, any event that does not meet this criteria is dropped.
• Errors: Number of events dropped due to transformation errors.
• Events transformed: Number of events successfully transformed and forwarded for further processing.

You can filter and view the metrics for the past 2 hours, 1 day, 7 days, or 30 days.

If you have connected the transformation to multiple destinations, you can view metrics for all destinations or select them individually. You also get the option of filtering the events by sources connected to those destinations.
