Le metriche e i log degli endpoint non vengono visualizzati
Se riesci a inviare richieste alla tua API, ma non visualizzi metriche o log nella pagina Endpoints > Servizi della consoleGoogle Cloud , svolgi i seguenti passaggi:
Se devi accedere ai log di Extensible Service Proxy (ESP) per diagnosticare i problemi, utilizza kubectl come segue:
Recupera il nome del pod:
kubectl get pod
NAME READY STATUS RESTARTS AGE
esp-echo-174578890-x09gl 2/2 Running 2 21s
Il nome del pod è esp-echo-174578890-x09gl e ha due container: esp
e echo.
Per visualizzare i log in un pod, usa kubectl logs:
kubectl logs POD_NAME -c CONTAINER_NAME
Dove POD_NAME e
CONTAINER_NAME vengono restituiti dal
comando
kubectl get pod nel passaggio precedente. Ad esempio:
kubectl logs esp-echo-174578890-x09gl -c esp
Verifica del nome del servizio
Se viene visualizzato il messaggio di errore Fetching service config failed, verifica che il nome del servizio specificato nel campo --service del file manifest del deployment (chiamato file deployment.yaml) corrisponda al nome host nella proprietà name specificata nel file YAML di configurazione dell'API gRPC (chiamato file api_config.yaml).
Se il nome errato è nel file deployment.yaml:
Apri il file deployment.yaml e vai alla sezione configurata per il contenitore ESP. Ad esempio:
Sostituisci SERVICE_NAME con il nome del
passaggio precedente. Sono necessari 30 giorni per l'eliminazione del servizio da Google Cloud.
Durante questo periodo non potrai riutilizzare il nome del servizio.
Apri il file api_config.yaml, correggi il nome host nella proprietà name e salva il file.
Esegui il deployment della configurazione del servizio aggiornata:
Attendi il completamento del deployment della configurazione del servizio.
Avvia il servizio Kubernetes:
kubectl create -f deployment.yaml
Controllo dei file di configurazione
Usa ssh per connetterti al pod utilizzando kubectl:
kubectl exec -ti -c CONTAINER_NAMEPOD_NAME bash
Sostituisci CONTAINER_NAME con il nome del contenitore e POD_NAME con il nome del pod.
Nella directory etc/nginx/endpoints/, controlla se sono presenti errori nei seguenti file di configurazione:
nginx.conf- Il file di configurazione nginx con le direttive ESP
service.jso - Il file di configurazione del servizio
Accedere alla pagina dello stato degli endpoint
Se hai impostato rollout_strategy su managed quando hai avviato ESP e devi conoscere l'ID configurazione utilizzato da un'istanza di ESP, le informazioni sono disponibili nella pagina Stato endpoint.
Per accedere alla pagina dello stato degli endpoint:
Usa ssh per connetterti al pod utilizzando kubectl:
kubectl exec -ti -c CONTAINER_NAMEPOD_NAME bash
Sostituisci CONTAINER_NAME con il nome del contenitore e POD_NAME con il nome del pod.
Il valore in rolloutId è l'ID configurazione del servizio utilizzato dall'ESP. Per assicurarti che ESP utilizzi la stessa configurazione di Endpoints, consulta Ottenere il nome del servizio e l'ID configurazione.

Authorize `gcloud`:\n\n gcloud auth login\n gcloud auth application-default login\n\n2. Create a cluster. You can either use the following `gcloud`command, or create\n a cluster using\n [Google Cloud console](https://console.cloud.google.com/kubernetes).\n\n ```\n gcloud container clusters create CLUSTER_NAME\n ```\n\n Replace \u003cvar translate=\"no\"\u003eCLUSTER_NAME\u003c/var\u003e with your cluster's name.\n3. Get credentials for your cluster and make them available to `kubectl`:\n\n ```\n gcloud container clusters get-credentials CLUSTER_NAME\n ```\n\nEndpoints metrics and logs aren't displayed\n-------------------------------------------\n\nIf you can successfully send requests to your API, but you don't see any\nmetrics or logs on the **Endpoints** \\\u003e **Services** page in the\nGoogle Cloud console, take the following steps:\n\n1. Check all the [required services](/endpoints/docs/openapi/get-started-kubernetes-engine#checking_required_services) are enabled.\n2. Check all the [required permissions](/endpoints/docs/openapi/get-started-kubernetes-engine#checking_required_permissions) are granted.\n\nAccessing logs from Extensible Service Proxy\n--------------------------------------------\n\nIf you need to access the Extensible Service Proxy (ESP) logs to diagnose\nproblems, use `kubectl` as follows:\n\n1. Get the name of the pod:\n\n kubectl get pod\n\n NAME READY STATUS RESTARTS AGE\n esp-echo-174578890-x09gl 2/2 Running 2 21s\n\n The pod name is `esp-echo-174578890-x09gl` and it has two containers: `esp`\n and `echo`.\n2. To view the logs in a pod use `kubectl logs`:\n\n ```\n kubectl logs POD_NAME -c CONTAINER_NAME\n ```\n\n Where `POD_NAME` and\n `CONTAINER_NAME` are returned from the\n `kubectl get pod`\n command, in the previous step. For example: \n\n kubectl logs esp-echo-174578890-x09gl -c esp\n\nVerifying the service name\n--------------------------\n\nIf you see the error message `Fetching service config failed`, verify that the service name that you specified in the `--service` field in your Deployment manifest file (referred to as the `deployment.yaml` file) matches the host name in the `name` property specified in your gRPC API configuration YAML file (referred to as the `api_config.yaml` file).\n\n\u003cbr /\u003e\n\n**If the incorrect name is in the `deployment.yaml` file**:\n\n1. Open the `deployment.yaml` file and go to the section configured for the\n ESP container. For example:\n\n ```\n containers:\n - name: esp\n image: gcr.io/endpoints-release/endpoints-runtime:1\n args: [\n \"--http_port=8081\",\n \"--backend=127.0.0.1:8080\",\n \"--service=SERVICE_NAME\",\n \"--rollout_strategy=managed\"\n ]\n \n ```\n\n Change \u003cvar translate=\"no\"\u003eSERVICE_NAME\u003c/var\u003e so that it matches the host name\n specified in the `name` property in the `api_config.yaml` file and save the\n `deployment.yaml` file.\n2. Start the Kubernetes service:\n\n kubectl create -f deployment.yaml\n\n**If the incorrect name is in the `api_config.yaml` file**:\n\n1. [Get the service name](/endpoints/docs/grpc/get-service-name-config-id)\n that Endpoints was configured to use.\n\n2. Delete the service:\n\n ```\n gcloud endpoints services delete SERVICE_NAME\n ```\n\n Replace \u003cvar translate=\"no\"\u003eSERVICE_NAME\u003c/var\u003e with the name from the previous\n step. It takes 30 days for the service to be deleted from Google Cloud.\n You aren't able to reuse the service name during this time.\n3. Open the `api_config.yaml` file and correct the host name in the\n `name` property and save the file.\n\n4. Deploy the updated service configuration:\n\n gcloud endpoints services deploy api_descriptor.pb api_config.yaml api_config_http.yaml\n\n Wait for the service configuration to be successfully deployed.\n5. Start the Kubernetes service:\n\n kubectl create -f deployment.yaml\n\nChecking configuration files\n----------------------------\n\n1. Use `ssh` to connect to the pod using `kubectl`:\n\n ```\n kubectl exec -ti -c CONTAINER_NAME POD_NAME bash\n ```\n\n Replace \u003cvar translate=\"no\"\u003eCONTAINER_NAME\u003c/var\u003e with the name of your\n container and \u003cvar translate=\"no\"\u003ePOD_NAME\u003c/var\u003e with the name of your pod.\n2. In the `etc/nginx/endpoints/` directory, check the following configuration\n files for errors:\n\n - `nginx.conf`- The `nginx` config file with ESP directives\n - `service.jso` - The service configuration file\n\nAccessing the Endpoints status page\n-----------------------------------\n\nIf you set `rollout_strategy` to `managed` when you started ESP,\nand you need to find out the configuration ID that an instance of\nESP is using, the Endpoints status page has the information.\n\nTo access the Endpoints status page:\n\n1. Use `ssh` to connect to the pod using `kubectl`:\n\n ```\n kubectl exec -ti -c CONTAINER_NAME POD_NAME bash\n ```\n\n Replace \u003cvar translate=\"no\"\u003eCONTAINER_NAME\u003c/var\u003e with the name of your\n container and \u003cvar translate=\"no\"\u003ePOD_NAME\u003c/var\u003e with the name of your pod.\n2. Install [`curl`](https://curl.haxx.se/download.html).\n\n3. Enter the following:\n\n curl http://localhost:8090/endpoints_status\n\n It displays something similar the following: \n\n \"serviceConfigRollouts\": {\n \"rolloutId\": \"2017-08-09r27\",\n \"percentages\": {\n \"2017-08-09r26\": \"100\"\n }\n }\n\nThe value in the `rolloutId` is the service configuration ID that\nESP is using. To make sure that ESP is using the\nsame configuration as Endpoints,\nsee\n[Getting the service name and configuration ID](/endpoints/docs/grpc/get-service-name-config-id)."]]
