Drill-down to service failure causes

To find the Failure rate tab, go to the service’s details page and select a View button (such as View requests, View dynamic requests, or View resource requests).

Select Analyze backtrace to see where these requests came from.

The requests originate from the weather-express service and nearly all failed requests to Redis have the same exception—an AbortError caused by a closed connection.

To analyze down to the affected Node.js traces, select More (…) > Distributed traces.

By looking at the Node.js trace and its code-level execution tree below, you can see that a Redis request leads to an error. You can see where this error occurs in the flow of the Node.js code.

Select the Errors tab to analyze the exception.
