Tutorial Custom pipeline-mapping with integrations

[Vince-dS]

Hi Team,
In 8.8 ( same in 8.13 ?), I am testing custom pipeline+mapping along an integration. I am also looking at this document: https://www.elastic.co/guide/en/fleet/current/data-streams-pipeline-tutorial.html.

To me, there are couple of points to correct:

• Where is the “Select Apply now and rollover.” ?
  Once updating a custom pipeline from the integration (advanced options), I do not see such option.
  I do an API request to trigger the rollover.

POST 	logs-nginx.access-default/_rollover 

• the proposition to rollover just after the custom pipeline should add some reminder about the mapping.
  Why not emphasising to check the custom mapping according to the custom pipeline ?
  To ensure, both have been tested and are ok before triggering the roll over.

FYI, I was initially suggesting this link to a customer who has moved from on prem. to the cloud with a strong interest to add pipeline/mapping along integrations.
Thanks

PS:
it is my first doc issue - pls let me know if I need to bring more detail/context.

@kilfoyle , fyi, while working on a training doc on this topic, I noted a reference which is mentioning rollover api instead of “Select Apply now and rollover.” :

• https://www.elastic.co/guide/en/observability/current/apm-ilm-how-to.html#apm-data-streams-custom-three

As well, a screenshot from v8.8 :

Hi @Vince-dS
I haven't really worked much with data streams or pipelines so I'm learning as I go. I tried to run through this tutorial and make the changes you suggested.

In "Step 2: Apply your ingest pipeline", as you suggest, I can add instructions to test the custom mapping:

Then, I can also add instructions to run a rollover (using the API, since I also don't see any "Apply now and rollover" button).

However,
Now, when I run this query:

GET metrics-system.cpu-default/_search
{
  "query": {
    "exists": {
      "field": "test"
    }
  }
}

I get a false result. :-(
I tried waiting 30 minutes and still no luck. If you know what I could be doing wrong I'd appreciate any tips.
