Description

Enable audit_log_enabled on MySQL flexible servers.

Rationale

Enabling audit_log_enabled helps MySQL to log items such as connection attempts, DDL/DML access, and other events. Log data can be used to identify, troubleshoot, and repair configuration errors and suboptimal performance.

Impact

There are additional costs for log storage. For high-traffic databases, these logs can be significant. Determine your organization's needs before enabling.

Audit

From Azure Portal

1. Log in to Azure Portal using https://portal.azure.com.
2. Select Azure Database for MySQL Servers.
3. For each database, under the Settings, click Server parameters.
4. In the filter bar, type audit_log_enabled.
5. Ensure that the VALUE for audit_log_enabled is ON.

From Azure CLI

Ensure the following command returns a value of on:

az mysql flexible-server parameter show \
    --resource-group {{resource-group-name}} \
    --server-name {{server-name}} \
    --name audit_log_enabled
