Track users impacted with errors inbox

New Relic agents automatically capture data about user impact. When you organize by error group, you can see how many users are affected by errors. This helps you prioritize where to focus your debugging efforts by showing you the errors with the highest numbers of users affected.

Custom attributes to track users impacted

In some cases, an error event may not have attributes that identify the end user affected by that error event. You can manually add custom attributes so our agents capture user-identifying metadata at the time of ingest.

For cases where you need to add a custom attribute, we recommend reviewing OpenTelemetry's attribute conventions because there are multiple common conventions for naming end user attributes.

For example, OpenTelemetry standards uses the following attributes in order of priority:

• userId
• user

You can review how New Relic processes custom attributes by reading our doc about collecting custom events.

Query for users impacted

The number of users impacted on an error group is recorded as a Metric data type with the name newrelic.error.group.userImpact. You can use this metric with the following NRQL string:

SELECT uniqueCount(newrelic.error.group.userImpact) 
FROM Metric 
WHERE metricName='newrelic.error.group.userImpact'

The metric captures the approximate number of unique users in the time period selected. Additional attributes provided by the userImpact metric which can be used in a FACET clause are error.group.guid, entity.guid.

Alert on users impacted

By creating an NRQL alert condition, developers can trigger alertas when the amount of users impacted by errors exceeds a threshold.

Creating this alert requires determining the NRQL query which measures the amount of users impacted in a way which best captures your use case.

As an example, the following NRQL query measures the amount of unique users which have been impacted by an error group coming from a specific entity:

SELECT uniqueCount(newrelic.error.group.userImpact) 
FROM Metric 
WHERE metricName='newrelic.error.group.userImpact' 
AND entity.guid='RXxCUk9XU9182nNEFQUExJQ0FLsU9OfDgzNzgwNw' FACET error.group.guid TIMESERIES

Similarly, the following NRQL query measures the total number of users impacted by errors from all entities under the account in the last hour:

SELECT count(newrelic.error.group.userImpact) 
FROM Metric 
WHERE metricName='newrelic.error.group.userImpact' SINCE 1 hour ago TIMESERIES

Once you have decided on a NRQL query, it can be used to create a NRQL alert condition.

Set users impacted with setUser method

You can use an agent method to identify an end user. See implementation details for each agent below:
