How to trace which external service call is slow

Currently, we are using this query SELECT max(newrelic.timeslice.value) from Metric WHERE appName =‘Magento - USA’ AND metricTimesliceName =‘External/allWeb’ to create alert when there is any slow external call.

However, after we receive the alert, we are unable to trace the exact call which is slow.

I try to explore APM & services > External services but there is no information.

Clicking on the first one, there is no data

I also notice when using query builder, there is no Span data.
Is there anything we can do to pinpoint the exact slow calls?

Hi @quangdp

Thanks for reaching out, I hope you are well.

Congrats on your first post in the community, Whoop!

Can you share the permalink to the alert in question as it will help us narrow down the cause if the issue.'APM'%2C%20'EXT')%20AND%20type%20IN%20('APPLICATION'%2C%20'SERVICE'))&state=918b6589-6271-ddb4-a3a8-3d629fee11ab

Some external calls here takes nearly 2s but when clicking on it, it doesn’t show any data.
