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."]]
