Después de agregar el SDK de App Check a la app, pero antes de habilitar
la aplicación de App Check, debes asegurarte de que esto no interrumpa a los
usuarios legítimos existentes.
En el caso de Cloud Functions, puedes obtener las métricas de App Check si examinas
los registros de las funciones. Cada invocación de una función que admite llamadas emite una entrada de registro estructurada como se ve en el siguiente ejemplo:
{"severity":"INFO",// INFO, WARNING, or ERROR"logging.googleapis.com/labels":{"firebase-log-type":"callable-request-verification"},"jsonPayload":{"message":"Callable header verifications passed.","verifications":{// ..."app":"MISSING",// VALID, INVALID, or MISSING}}}

Every invocation of a callable function emits a structured log\nentry like the following example: \n\n {\n \"severity\": \"INFO\", // INFO, WARNING, or ERROR\n \"logging.googleapis.com/labels\": {\"firebase-log-type\": \"callable-request-verification\"},\n \"jsonPayload\": {\n \"message\": \"Callable header verifications passed.\",\n \"verifications\": {\n // ...\n \"app\": \"MISSING\", // VALID, INVALID, or MISSING\n }\n }\n }\n\nYou can analyze these metrics in the Google Cloud console by [creating a\nlogs-based counter metric](https://cloud.google.com/logging/docs/logs-based-metrics/counter-metrics)\nwith the following metric filter: \n\n```\nresource.type=\"cloud_function\"\nresource.labels.function_name=\"YOUR_CLOUD_FUNCTION\"\nresource.labels.region=\"us-central1\"\nlabels.firebase-log-type=\"callable-request-verification\"\n```\n\n[Label the metric](https://cloud.google.com/logging/docs/logs-based-metrics/labels#create-label)\nusing the field `jsonPayload.verifications.appCheck`.\n\nNext steps\n\nWhen you understand how App Check will affect your users and you're ready to\nproceed, you can [enable App Check enforcement](/docs/app-check/cloud-functions)\nfor Cloud Functions."]]
