Below are the metrics I am talking about. Please double check if we need
these as well to be documented.
**NodeDecommissionMetrics (entire section missing**)
This metrics class is not documented. It tracks decommissioning and
maintenance workflows.
**Aggregate metrics (cluster-wide):**
- **DecommissioningMaintenanceNodesTotal**
(`node_decommission_metrics_decommissioning_maintenance_nodes_total`): Number
of nodes tracked for decommissioning and maintenance
- **RecommissionNodesTotal**
(`node_decommission_metrics_recommission_nodes_total`): Number of nodes tracked
for recommissioning
- **PipelinesWaitingToCloseTotal**
(`node_decommission_metrics_pipelines_waiting_to_close_total`): Number of nodes
tracked with pipelines waiting to close
- **ContainersUnderReplicatedTotal**
(`node_decommission_metrics_containers_under_replicated_total`): Number of
containers under replicated in tracked nodes
- **ContainersUnClosedTotal**
(`node_decommission_metrics_containers_un_closed_total`): Number of containers
not fully closed in tracked nodes
- **ContainersSufficientlyReplicatedTotal**
(`node_decommission_metrics_containers_sufficiently_replicated_total`): Number
of containers sufficiently replicated in tracked nodes
**Per-host metrics (tagged by datanode hostname):**
- **UnderReplicatedDN** (`node_decommission_metrics_under_replicated_dn`):
Number of under-replicated containers for the specific host
- **PipelinesWaitingToCloseDN**
(`node_decommission_metrics_pipelines_waiting_to_close_dn`): Number of
pipelines waiting to close for the specific host
- **SufficientlyReplicatedDN**
(`node_decommission_metrics_sufficiently_replicated_dn`): Number of
sufficiently replicated containers for the specific host
- **UnclosedContainersDN**
(`node_decommission_metrics_unclosed_containers_dn)`: Number of containers not
fully closed for the specific host
- **StartTimeDN** (`node_decommission_metrics_start_time_dn`): Timestamp
when decommissioning was started for the specific host
