Datadog Autotest: FAIL

The new RDS page sends the benchmark link to MariaDB performance schema documentation. The menu weight change also moves Terraform before ClickHouse.

P2 Keep the ClickHouse menu order

The change moves an unrelated menu entry and changes the existing navigation order.

Assertion details
  • Input: Render the Database Monitoring menu after this change.
  • Expected: ClickHouse stays before Terraform, as it was before this change.
  • Actual: ClickHouse and Terraform both have weight 10. Hugo sorts Terraform before ClickHouse when weights are equal.
