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

azure.dbforpostgresql

Set up the azure.dbforpostgresql integration.

Description

Enable log_connections on PostgreSQL Servers.

Rationale

Enabling log_connections helps PostgreSQL Database to log an attempted connection to the server, as well as successful completion of client authentication. Log data can be used to identify, troubleshoot, and repair configuration errors and suboptimal performance.

Remediation

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_connections.
  5. Click ON and save.

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

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