Using elastic-package to install the scenario (with these instructions: https://github.com/elastic/elastic-package/blob/main/docs/howto/use_existing_stack.md).

@jsoriano it looks like there is no "Index Template" created when these input packages using otelcol input are installed:

As a reference, for instance sql_input input package creates this Index Template:

This makes the system test fail with this error:

[0] failed to load mappings from index template preview (metrics-httpcheck.check.otel): error getting mapping: [400 Bad Request] {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"unable to simulate template [metrics-httpcheck.check.otel] that does not exist"}],"type":"illegal_argument_exception","reason":"unable to simulate template [metrics-httpcheck.check.otel] that does not exist"},"status":400}

This is used to get the mappings that were installed to compare them with those that are available after being ingested the documents.

Ok, it seems that it is pending as mentioned in elastic/kibana#232628

In addition they should contain @package and @custom templates included in current packages, so package developers and users can still customize mappings or pipelines.

Do you think there is going to be an Index Template installed for that as in the other packages?
