OpenTelemetry performance alerting

AppSignal supports OpenTelemetry trace data. It's now possible to set up performance alerting for traces.

In a trace summary view, click the "Add new" link in the "Triggers" box.

Trace summary page with the triggers box highlighted

In the opened "New trigger" modal, configure the alerting, select your preferred notifier, and save the trigger.

It is possible to configure alerting on the mean response time of requests, and the 90th and 90th percentile of the response time. Use a warm-up to only be alerted if this continues for as long as the warm-up is configured.

Now, AppSignal will alert you about new slow actions.
