``monitoring_port`` from the spec.
* The number of entries in ``colocation_ports`` should be ``count - 1``,
to cover the node down scenario (or ``count_per_host - 1`` when using ``count_per_host``).
- * Each entry must specify both ``data_port`` and ``monitoring_port``. When
- ``enable_rdma`` is true, each entry must also include ``rdma_port``.
+ * Each entry must specify ``data_port``, ``monitoring_port``, and ``qos_cluster_port``.
+ When ``enable_rdma`` is true, each entry must also include ``rdma_port``.
* If ``colocation_ports`` is not specified, ports will be automatically
incremented for colocated daemons (e.g., 2049 → 2050 → 2051 for data ports,
and 9587 → 9588 → 9589 for monitoring ports).
