The server should have the parameter 'log_checkpoints' enabled for PostgreSQL

azure.dbforpostgresql

Warning: This rule will be deprecated 18 December 2023 as part of the update to Azure CIS version 2.0.0

Description

Enable log_checkpoints on PostgreSQL Servers.

Rationale

Enabling log_checkpoints helps the PostgreSQL Database to log each checkpoint and generate query and error logs. Access to transaction logs is not supported. Query and error logs can be used to identify, troubleshoot, and repair configuration errors and sub-optimal 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_checkpoints.
  5. Click ON and save.

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

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