Set server parameter 'log_disconnections' to 'ON' for PostgreSQL Database Server (Automated)
Profile Applicability
• Level 1
Description
Enable log_disconnections on PostgreSQL Servers.
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.
