Overview
Enable log_checkpoints on PostgreSQL flexible servers.
Rationale
Enabling log_checkpoints helps the PostgreSQL Database to Log each checkpoint, which generates query and error logs. However, 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.
Default Value
By default, log_checkpoints is enabled (set to on).
Remediation guidance
Remediate from Azure Portal
- Open the server using the
Open in Azurebutton - Under
Settings, clickServer parameters. - In the filter bar, type
log_checkpoints. - Set the
VALUEforlog_checkpointstoON. - Click
Save.
Remediate from Azure CLI
Use the below command to enable log_checkpoints:
az postgres flexible-server parameter set --resource-group <resourceGroup> --server-name <serverName> --name log_checkpoints --value on
Remediate from PowerShell
Update-AzPostgreSqlFlexibleServerConfiguration -ResourceGroupName <resourceGroup> -ServerName <serverName> -Name log_checkpoints -Value on
Service-wide remediation
Recommended when many resources are affected: fix the platform baseline first so new resources inherit the secure setting, then remediate the existing flagged resources in batches.
Azure
Use management group or subscription Azure Policy assignments, remediation tasks where supported, landing-zone standards, and IaC modules so drift is prevented at scale.
Operational rollout
- Fix the baseline first at the account, subscription, project, cluster, or tenant scope that owns this control.
- Remediate the currently affected resources in batches, starting with internet-exposed and production assets.
- Re-scan and track approved exceptions with an owner and expiry date.
Query logic
These are the stored checks tied to this control.
