Logstash monitoring shows all metrics except pipeline details

[BradVido]

I'm using Elastic stack 7.8.1, and have configured X-pack monitoring for Logstash in logstash.yml by setting xpack.monitoring.enabled: true.

In the Kibana UI, I see metrics, as expected here:

And here:

But the data I'm really interested in (pipeline details), shows all zeroes:

I do have the undocumented xpack.monitoring.collection.pipeline.details.enabled option set to true, but that didn't seem to help.

Last thing of note is that I am on Windows Server 2016.

What am I missing?

Replying with the solution: "be patient"

After about 20 minutes, the stats started to show up in the pipeline metrics.

It would be great if the documentation mentioned this!
