Molti linguaggi di programmazione hanno interfacce standard di scrittura dei log che puoi
riconfigurare per utilizzare Logging.
Scrittura di log
Per scrivere log in Cloud Logging, puoi eseguire una delle seguenti operazioni:
Scrivi i log nei file di log esistenti, ad esempio syslog, nell'istanza VM di Compute Engine e utilizza Ops Agent per inviare i log a Cloud Logging. Per saperne di più, consulta la pagina
Agenti Google Cloud Observability.
Configura un pacchetto di logging standard in modo che invii i log che scrivi a
Logging. Per ulteriori informazioni, consulta le seguenti pagine
di dettagli:
Utilizza gcloud CLI. Per saperne di più, consulta l'interfaccia a riga di comando gcloud logging.
Associare i dati di traccia alle voci di log
Le voci di log possono contenere informazioni sulle tracce. Se includi i dati di traccia
nelle voci di log, puoi correlare log e tracce per una migliore
risoluzione dei problemi distribuiti. Per informazioni sull'acquisizione manuale e automatica delle informazioni di traccia nelle voci di log, consulta Eseguire l'integrazione con Cloud Logging.
Leggere i log
Per leggere le voci di log in Logging, puoi procedere in uno dei seguenti modi:
Nella Google Cloud console, vai alla pagina Esplora log:

Several open-source instrumentation frameworks let you collect metrics, logs, and traces from your application and send that data to any vendor, including Google Cloud. To instrument your application, we recommend that you use a vendor-neutral instrumentation framework that is open source, such as [OpenTelemetry](https://opentelemetry.io/), instead of vendor- and product-specific APIs or client libraries.\n|\n| \u003cbr /\u003e\n|\n| For information about instrumenting your applications by using\n| vendor-neutral instrumentation frameworks, see\n| [Instrumentation and observability](/stackdriver/docs/instrumentation/overview).\n\nWrite logs\n----------\n\nTo write logs to Cloud Logging, you can do any of\nthe following:\n\n- Write your logs to existing log files such as `syslog` on your Compute EngineVM instance and use the Ops Agent to send the logs to Cloud Logging. For more information, see [Google Cloud Observability agents](/logging/docs/agent).\n- Configure a standard logging package to send the logs you write to Logging. For more information, see the following detail pages:\n - Any language: [fluentd](https://www.fluentd.org/)\n - [C#: Using ASP.NET or calling\n the API](/logging/docs/integrate/dotnet)\n - [Java: Using Logback and\n java.util.logging](/logging/docs/setup/java)\n - [Go: Using standard logging](/logging/docs/setup/go)\n - [Node.js: Using Winston and Bunyan](/logging/docs/setup/nodejs)\n - [PHP: Using PSR-3 logger](/logging/docs/setup/php)\n - [Python: Using the standard logging\n facility](/logging/docs/setup/python)\n - [Ruby: Using the Google Cloud Observability\n gem](/logging/docs/setup/ruby)\n- Call the Logging API using Logging's [Client Libraries](/logging/docs/reference/libraries) for your programming language.\n- Call the Logging API REST endpoint directly. See the [Logging API reference documentation](/logging/docs/reference/v2/rest).\n- Use the [gcloud CLI](/sdk/docs). For more information, see the [`gcloud logging`](/logging/docs/reference/tools/gcloud-logging) command-line interface.\n\n\u003cbr /\u003e\n\n| **Note:** Incoming log entries with timestamps that are more than the [logs retention period](/logging/quotas#logs_retention_periods) in the past or that are more than 24 hours in the future are discarded.\n\nAssociate trace data with log entries\n-------------------------------------\n\nLog entries can contain information about traces. By including trace data\nin log entries, you can correlate logs and traces to enable better\ndistributed troubleshooting. For information about manual and\nautomatic capture of trace information in log entries, see\n[Integrate with Cloud Logging](/trace/docs/trace-log-integration).\n\nRead logs\n---------\n\nTo read log entries in Logging, you can do any of\nthe following:\n\n- In the Google Cloud console, go to the **Logs Explorer** page:\n\n [Go to **Logs Explorer**](https://console.cloud.google.com/logs/query)\n\n \u003cbr /\u003e\n\n If you use the search bar to find this page, then select the result whose subheading is\n **Logging**.\n\n For more information, see\n [Logs Explorer overview](/logging/docs/view/logs-explorer-interface).\n- Call the Logging API through\n the [client libraries](/logging/docs/reference/libraries) for your\n programming language.\n\n- Call the Logging API REST endpoints directly.\n See the [Logging API reference documentation](/logging/docs/reference/v2/rest).\n\n- Use the [gcloud CLI](/sdk/docs).
