See the [Cloud Logging documentation](/logging/docs)\nfor complete information and review the\n[Cloud SQL sample queries](/logging/docs/view/query-library-preview#sql-filters).\n\nTo view logs for your Cloud SQL instance log entries: \n\n### Console\n\n1. [Go to the Logs Explorer](https://console.cloud.google.com/logs/query)\n2. Select an existing Cloud SQL project at the top of the page.\n3. In the Query builder, add the following:\n - Resource: select **Cloud SQL Database**. In the dialog, select a Cloud SQL instance.\n - Log names: scroll to the Cloud SQL section and select appropriate log files for your instance. For example:\n - cloudsql.googleapis.com/postgres.log\n - Severity: select a log level.\n - Time range: select a preset or create a custom range.\n\n### gcloud\n\nUse the [`gcloud logging`](/sdk/gcloud/reference/logging/read)\ncommand to view log entries. In the example below, replace \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e.\nThe [`limit`](/sdk/gcloud/reference/logging/read#--limit)\nflag is an optional parameter that indicates the maximum number of entries to\nreturn. \n\n```bash\ngcloud logging read \"projects/[PROJECT_ID]/logs/cloudsql.googleapis.com/postgres.log\" --limit=10\n```"]]
