Friendly ping for review @elastic/integrations-triaging

LGTM as initial version.

Would it be possible to add tests?

Policy tests should be easy to add and they would be specially relevant now that we are stabilizing latest changes in Fleet for OTel integrations, and I think this one would be the first one for profiles.

I have skipped tests, as they fail with an error that seems unrelevant to the package:

ERROR: there was an apply error: could not add package policy "test-with-samples-per-second-profiling_otel-24460" to agent policy "test-with-samples-per-second-24460": could not create package policy (req {"name":"test-with-samples-per-second-profiling_otel-24460","description":"","namespace":"ep","policy_id":"6338e69c-3ccf-4b94-9fa5-d1cd5b29a5ba","package":{"name":"profiling_otel","version":"0.0.1"},"inputs":{"profilingreceiver-otelcol":{"enabled":true,"streams":{"profiling_otel.profilingreceiver":{"enabled":true,"vars":{"data_stream.dataset":"profilingreceiver","samples_per_second":73}}}}},"force":false}); API status code = 400; response body = {"statusCode":400,"error":"Bad Request","message":"unexpected data stream type profiles"}

This package does not set or define datastreams.

🟢 Low policy/test-with-samples-per-second.expected:6

The elasticsearch/componentid-0 exporter references beatsauth/default (line 6), but no extension by that name exists. The actual extension defined is beatsauth/componentid-0 (line 10), and that's what's registered in service.extensions (line 42). This mismatch causes the OpenTelemetry Collector configuration validation to fail at startup with an unknown extension reference error.

Suggested change

	authenticator: beatsauth/default
	authenticator: beatsauth/componentid-0

@elastic/integrations-triaging is this expected?

[jsoriano]

This is expected, but for the fingerprint diff found in CI you will have to wait for a release of elastic-package with elastic/elastic-package#3467 (coming soon).

To unblock this skip the policy test by now, and we will remove the skip after releasing the next elastic-package version.

[florianl]

not sure if c5d8f8a is the correct way to skip this test. looking at other packages this seems to be the only way - didn't find documentation.
