This page describes how to find and use Cloud Logging to view and query logs for your Cloud SQL instance.
Cloud SQL uses Cloud Logging. See the cloud logging documentation for complete information and review the Cloud SQL sample queries.
View logsTo view logs for your Cloud SQL instance log entries:
ConsoleIn the Google Cloud console, go to the Cloud Logging page.
Use the gcloud logging
command to view log entries. In the example below, replace PROJECT_ID
. The limit
flag is an optional parameter that indicates the maximum number of entries to return.
gcloud logging read "resource.type=cloudsql_database" \ --project=PROJECT-ID \ --limit=10 \ --format=jsonView instance operations log
You can view the logs for an instance in the Operations pane. The Operations pane logs every operation performed on the instance with the following information:
If the operation fails, you can use the message to troubleshoot the problem.
To view an instance operations log:
In the Google Cloud console, go to the Cloud SQL Instances page.
The operations log does not include operations performed using external management tools, such as SQL Server command-line tools. Only user management and password change operations performed using the Google Cloud console,
gcloud CLI, or the Cloud SQL Admin API appear in the operations log.
View application logsApplications that connect to Cloud SQL store their logs in different locations.
App Engine (flexible environment)In Compute > App Engine > Services:
In the Operations > Logging > Logs explorer section of Google Cloud console, use the following query:
resource.type="gae_app"
resource.labels.module_id="default"
Cloud Run
View the logs in the Cloud Run Logs Explorer section of the Google Cloud console. Note that Cloud Run reports only error messages from the Cloud SQL Auth Proxy. Use a query like the following:
resource.type="cloud_run_revision"
resource.labels.service_name="$SERVICE_NAME"
resource.labels.revision_name="$REVISION_NAME"
Cloud SQL Auth Proxy
In Operations > Logging > Logs explorer, use the following query:
log_id("appengine.googleapis.com/cloud-sql-proxy")
View audit logs
You can view the following types of audit logs for your Cloud SQL instances:
For more information about viewing Admin Activity, Data Access, and System Event audit logs, see View logs.
PricingFor more information about Cloud Logging pricing, see Cloud Logging pricing summary.
Troubleshoot Issue Troubleshooting Audit logs are not found. Data-Access logs are only written if the operation is an authenticated user-driven API call that creates, modifies, or reads user-created data, or if the operation accesses configuration files or metadata of resources. Operations information is not found in logs. You want to find more information about an operation.For example, a user was deleted but you can't find out who did it. The logs show the operation started but don't provide any more information. You must enable audit logging for detailed and personal identifying information (PII) like this to be logged.
Some logs are filtered from theerror.log
log of a Cloud SQL for SQL Server instance. Filtered logs include AD logs without timestamps, and include: Login failed for user 'x'. Reason: Token-based server access validation failed with an infrastructure error. Login lacks connect endpoint permission. [CLIENT: 127.0.0.1]
. These logs are filtered because they potentially can cause confusion. Log files are hard to read. You'd rather view the logs as json or text.You can use the gcloud logging read
command along with linux post-processing commands to download the logs.
To download the logs as JSON:
gcloud logging read \ "resource.type=cloudsql_database \ AND logName=projects/PROJECT_ID \ /logs/cloudsql.googleapis.com%2FLOG_NAME" \ --format json \ --project=PROJECT_ID \ --freshness="1d" \ > downloaded-log.json
To download the logs as TEXT:
gcloud logging read \ "resource.type=cloudsql_database \ AND logName=projects/PROJECT_ID \ /logs/cloudsql.googleapis.com%2FLOG_NAME" \ --format json \ --project=PROJECT_ID \ --freshness="1d"| jq -rnc --stream 'fromstream(1|truncate_stream(inputs)) \ | .textPayload' \ --order=asc > downloaded-log.txt
