EventBridge:Query events

Last Updated:Mar 11, 2026

EventBridge Event Tracking lets you look up events by ID or filter by time range. You can then inspect the event trace to view event information and delivery details.

Prerequisites

Before you begin, make sure that you have:

Navigate to Event Tracking

Both query methods start from the same page. Complete these steps first:

  1. Log on to the EventBridge console.

  2. In the left-side navigation pane, click Event Buses.

  3. In the top navigation bar, select a region.

  4. On the Event Buses page, click the name of the event bus.

  5. In the left-side navigation pane, click Event Tracking.

Query by event ID

Use this method when you already have the event ID and want to go straight to its processing status.

  1. On the Event Tracking page, click the Query By Event ID tab.

  2. Enter the event ID and click Query.

The matching event appears in the result list. See View event trace and details to inspect the event.

Query by time range

Use this method to find events within a specific time window. You can narrow results by source, type, or rule.

  1. On the Event Tracking page, click the Query By Time Range tab.

  2. Set the query parameters and click Query.

    ParameterRequiredDescription
    Time RangeYesSelect a preset range, or specify a custom start time and end time from the drop-down list
    Event SourceNoFilter by event source
    Event TypeNoFilter by event type
    Rule NameNoFilter by event rule

Matching events appear in the result list. See View event trace and details to inspect an event.

View event trace and details

The result list shows all matching events. For each event, the Operations column provides two actions:

Event Trace

Click Event Trace to see how EventBridge processed the event. The trace is split into two sections:

  • Event Reception: When and how the event was ingested.

  • Event Delivery: Delivery details for each target.

Note To save the trace data, click Export Event Trace in the upper-right corner of the Event Trace message.

Event Detail

Click Event Detail to view the full event payload in JSON format. The following sample shows the parameters of an event:
