Description​

Enable log_disconnections on PostgreSQL Servers.

NOTE: This recommendation currently only applies to Single Server, not Flexible Server. See additional information below for details about the planned retirement of Azure PostgreSQL Single Server.

Rationale​

Enabling log_disconnections helps PostgreSQL Database to Logs end of a session, including duration, which in turn generates query and error logs. Query and error logs can be used to identify, troubleshoot, and repair configuration errors and sub-optimal performance.

Impact​

Enabling this setting will enable a log of all disconnections. If this is enabled for a high traffic server, the log may grow exponentially.

Audit​

From Azure Portal​
  1. From Azure Home select the Portal Menu.
  2. Go to Azure Database for PostgreSQL servers.
  3. For each database, under Settings, click Server parameters.
  4. Search for log_disconnections.
  5. Ensure that log_disconnections is set to ON.
From Azure CLI​

Ensure log_disconnections value is set to ON:
