Server parameter 'log_disconnections' is set to 'ON' for PostgreSQL Database Server


Set up the azure.dbforpostgresql integration.


Enable log_disconnections on PostgreSQL Servers.


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


From the console

  1. Login to Azure Portal using https://portal.azure.com
  2. Go to Azure Database for PostgreSQL server
  3. For each database, click on Server parameters
  4. Search for log_disconnections.
  5. Click ON and save.

Alternatively, use the Azure Command Line Interface and run the below command to update log_disconnections configuration:

az postgres server configuration set --resource-group <resourceGroupName> --server-name <serverName> --name log_disconnections --value on
