Descriptionโ€‹

Enabling the log_disconnections setting logs the end of each session, including the session duration.

Rationaleโ€‹

PostgreSQL does not log session details such as duration and session end by default. Enabling the log_disconnections setting will create log entries at the end of each session which can be useful in troubleshooting issues and determine any unusual activity across a time period. The log_disconnections and log_connections work hand in hand and generally, the pair would be enabled/disabled together. This recommendation is applicable to PostgreSQL database instances.

Impactโ€‹

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.

Remediationโ€‹

From Google Cloud Consoleโ€‹

  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 a Database Flag, choose the flag log_disconnections from the drop-down menu and set the value as on.
  6. Click Save.
  7. Confirm the changes under Flags on the Overview page.

From Google Cloud CLIโ€‹

  1. Configure the log_disconnections database flag for every Cloud SQL PosgreSQL database instance using the below command:

         gcloud sql instances patch <INSTANCE_NAME> --database-flags log_disconnections=on

Note: This command will overwrite all previously set database flags. 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 ("=").
