Live Events
Detailed technical description of the Live Events feature to debug your source and destination events in real-time.
RudderStack's Live Events is a debugger that shows a stream of live events collected from your sources and sent to the connected destinations in real-time.
With this feature, you can easily debug any errors in the failing events at a destination level and reduce your troubleshooting time and efforts.
To use this feature, make sure you have configured your source and destination in RudderStack. For more information on adding a source and destination in RudderStack, follow this guide.

Source Live Events

The Live Events feature gives you real-time visibility into the source events collected by RudderStack. The key information includes:
    The name of the event.
    The type of the event collected from the source.
    Date and time of the collected event.
This feature is very handy in case you want to check if your source is correctly configured. For example, you can check if your JavaScript SDK loads correctly on your website.

Destination Live Events

When routing events to a destination, it can be frustrating if the events sent do not show up in the destination and not knowing the reason for failure only makes it worse.
The Live Events feature gives you real-time visibility into the destination's responses. The key information captured includes:
    Event Name: Corresponding to the name of the event.
    Error Code: In case the event fails, this gives specific details related to the error. These details include the error response and the date and time of the attempt to send the event.
The payload sent to the destination can be seen by clicking on an event. This is shown in the right-hand side window on the same page, as shown:

Use-case

Suppose you are trying to send some events to Facebook Custom Audience but they are not being delivered. Upon checking the Live Events tab for the Custom Audience destination, you see the following error in the UI:
You can click on the See full error option to see the error response, as shown:
As seen above, you were trying to send an identify event to Facebook Custom Audience, which the destination does not support. You can refer to the Custom Audience documentation to confirm that only track events are supported. As a result, when RudderStack tries sending the identify event to the destination, an error is thrown. RudderStack tries sending this event several times before marking it as aborted.
The responses received from the destination help you in quickly identifying and resolving the issues.
Live events are shown for all the destinations. However, the payload of the events is not shown for some destinations like the object storage platforms and the data warehouses supported by RudderStack.

Transformation Live Events

RudderStack also gives you the option of viewing the events before and after a transformation is applied.
RudderStack also notifies you about any dropped events or any errors during the transformation along with the details, as shown in the following image:
Note that this feature is applicable for cases where you have connect a transformation to a destination, as shown:

FAQs

Why are my events failing?

Routing events to a destination can fail for various reasons. Often, it is because the destination is configured incorrectly. Some other reasons could be incorrect/bad event payload structure, rate-limiting by the destination, etc. In some rare cases, the destination could be down too.
