MetricDefinitionRequest

Use this structure to define one extended metric or custom metric that RUM will send to CloudWatch or CloudWatch Evidently. For more information, see Custom metrics and extended metrics that you can send to CloudWatch and CloudWatch Evidently.

This structure is validated differently for extended metrics and custom metrics. For extended metrics that are sent to the AWS/RUM namespace, the following validations apply:

• The Namespace parameter must be omitted or set to AWS/RUM.

• Only certain combinations of values for Name, ValueKey, and EventPattern are valid. In addition to what is displayed in the following list, the EventPattern can also include information used by the DimensionKeys field.

• If Name is PerformanceNavigationDuration, then ValueKeymust be event_details.duration and the EventPattern must include {"event_type":["com.amazon.rum.performance_navigation_event"]}

• If Name is PerformanceResourceDuration, then ValueKeymust be event_details.duration and the EventPattern must include {"event_type":["com.amazon.rum.performance_resource_event"]}

• If Name is NavigationSatisfiedTransaction, then ValueKeymust be null and the EventPattern must include { "event_type": ["com.amazon.rum.performance_navigation_event"], "event_details": { "duration": [{ "numeric": [">",2000] }] } }

• If Name is NavigationToleratedTransaction, then ValueKeymust be null and the EventPattern must include { "event_type": ["com.amazon.rum.performance_navigation_event"], "event_details": { "duration": [{ "numeric": [">=",2000,"<"8000] }] } }

• If Name is NavigationFrustratedTransaction, then ValueKeymust be null and the EventPattern must include { "event_type": ["com.amazon.rum.performance_navigation_event"], "event_details": { "duration": [{ "numeric": [">=",8000] }] } }

• If Name is WebVitalsCumulativeLayoutShift, then ValueKeymust be event_details.value and the EventPattern must include {"event_type":["com.amazon.rum.cumulative_layout_shift_event"]}

• If Name is WebVitalsFirstInputDelay, then ValueKeymust be event_details.value and the EventPattern must include {"event_type":["com.amazon.rum.first_input_delay_event"]}

• If Name is WebVitalsLargestContentfulPaint, then ValueKeymust be event_details.value and the EventPattern must include {"event_type":["com.amazon.rum.largest_contentful_paint_event"]}

• If Name is JsErrorCount, then ValueKeymust be null and the EventPattern must include {"event_type":["com.amazon.rum.js_error_event"]}

• If Name is HttpErrorCount, then ValueKeymust be null and the EventPattern must include {"event_type":["com.amazon.rum.http_event"]}

• If Name is SessionCount, then ValueKeymust be null and the EventPattern must include {"event_type":["com.amazon.rum.session_start_event"]}

• If Name is PageViewCount, then ValueKeymust be null and the EventPattern must include {"event_type":["com.amazon.rum.page_view_event"]}

• If Name is Http4xxCount, then ValueKeymust be null and the EventPattern must include {"event_type": ["com.amazon.rum.http_event"],"event_details":{"response":{"status":[{"numeric":[">=",400,"<",500]}]}}} }

• If Name is Http5xxCount, then ValueKeymust be null and the EventPattern must include {"event_type": ["com.amazon.rum.http_event"],"event_details":{"response":{"status":[{"numeric":[">=",500,"<=",599]}]}}} }

For custom metrics, the following validation rules apply:

• The namespace can't be omitted and can't be AWS/RUM. You can use the AWS/RUM namespace only for extended metrics.

• All dimensions listed in the DimensionKeys field must be present in the value of EventPattern.

• The values that you specify for ValueKey, EventPattern, and DimensionKeys must be fields in RUM events, so all first-level keys in these fields must be one of the keys in the list later in this section.

• If you set a value for EventPattern, it must be a JSON object.

• For every non-empty event_details, there must be a non-empty event_type.

• If EventPattern contains an event_details field, it must also contain an event_type. For every built-in event_type that you use, you must use a value for event_details that corresponds to that event_type. For information about event details that correspond to event types, see RUM event details.

• In EventPattern, any JSON array must contain only one value.

Valid key values for first-level keys in the ValueKey, EventPattern, and DimensionKeys fields:

• account_id

• application_Id

• application_version

• application_name

• batch_id

• event_details

• event_id

• event_interaction

• event_timestamp

• event_type

• event_version

• log_stream

• metadata

• sessionId

• user_details

• userId
