Description​

The log_min_duration_statement flag defines the minimum amount of execution time of a statement in milliseconds where the total duration of the statement is logged. Ensure that log_min_duration_statement is disabled, i.e., a value of -1 is set.

Rationale​

Logging SQL statements may include sensitive information that should not be recorded in logs. This recommendation is applicable to PostgreSQL database instances.

Impact​

Turning on logging will increase the required storage over time. Mismanaged logs may cause your storage costs to increase. Setting custom flags via command line on certain instances will cause all omitted flags to be reset to defaults. This may cause you to lose custom flags and could result in unforeseen complications or instance restarts. Because of this, it is recommended you apply these flags changes during a period of low usage.

Remediation​

From Google Cloud Console​

  1. Go to the Cloud SQL Instances page in the Google Cloud Console by visiting https://console.cloud.google.com/sql/instances.
  2. Select the PostgreSQL instance where the database flag needs to be enabled.
  3. Click Edit.
  4. Scroll down to the Flags section.
  5. To set a flag that has not been set on the instance before, click Add item, choose the flag log_min_duration_statement from the drop-down menu and set a value of -1.
  6. Click Save.
  7. Confirm the changes under Flags on the Overview page.

From Google Cloud CLI​

  1. List all Cloud SQL database instances using the following command:

         gcloud sql instances list

  2. Configure the log_min_duration_statement flag for every Cloud SQL PosgreSQL database instance using the below command:

         gcloud sql instances patch <INSTANCE_NAME> --database-flags log_min_duration_statement=-1

Note: This command will overwrite all database flags previously set. To keep those and add new ones, include the values for all flags to be set on the instance; any flag not specifically included is set to its default value. For flags that do not take a value, specify the flag name followed by an equals sign ("=").
