The event metrics covered in this guide may not reflect real-time events due to reporting latency.
Click the Events tab on your transformation page to view detailed metrics for the events processed by the transformation. It includes the following details:
Total events ingested for transformation.
Number of events dropped intentionally by the transformation (because of the transformation’s logic). For example, if your transformation allowlists only track events with the name Product Purchased, any event that does not meet these criteria is dropped.
Number of events dropped due to transformation errors.
Number of events successfully transformed and forwarded for further processing.
Filtering window
You can filter the above metrics by source, destination, and time period (past 2 hours, 1 day, 7 days, or 30 days).
The 2-hour filtering window is available only in RudderStack’s Growth and Enterprise plans.
For Free plan users, the default filtering window is 1 day.
