 ## Overview
 
 ### PMM
 
-Shows the overall health status of PMM server pods with green **Healthy** when all pods are running normally or red **Not Healthy** when one or more pods are down.
+Shows PMM instances alive versus expected and the resulting health percentage.
 
 In HA Cluster mode, you have three PMM server replicas providing full redundancy. If one replica fails, the remaining two continue serving requests with no user-visible impact, but you should investigate quickly to restore full redundancy. 
 
-Check the **PMM Pods** table in the Pod Status Details section below to see which specific pods are affected.
+The **Active PMM Instance** panel identifies the current Raft leader. Check the **PMM Pods** table to see every instance's status and Active or Follower role.
 
 ### PostgreSQL
 
-Shows the overall health status of PostgreSQL database pods. Green **Healthy** indicates the cluster is fully operational with primary and replicas running. Red **Not Healthy** signals the cluster is degraded, putting metadata and configuration storage at risk.
+Shows PostgreSQL instances alive versus expected. The **PostgreSQL Primary** panel identifies the current primary, and the instance table reports replication streaming health.

 ### ClickHouse
 
-Shows the overall health status of ClickHouse pods. Green **Healthy** indicates the cluster is operating normally with all keeper and database nodes running. Red **Not Healthy** signals Query Analytics data storage is degraded.
+Shows ClickHouse database and Keeper nodes alive versus expected.
 
 ClickHouse stores all Query Analytics (QAN) data. When pods fail, QAN dashboards will show incomplete query performance metrics, you won't be able to analyze slow queries during the outage, and you'll have permanent gaps in your historical query analysis data.
 
-Check the **ClickHouse Pods** panel in the **ClickHouse Pod's Status** section below to see which pods are down. 
+Check the **ClickHouse Pods** panel to distinguish database (`pmmdb`) and Keeper nodes and to identify the Keeper leader. The dashboard reports Kubernetes node role and Keeper election state; it does not infer ClickHouse logical shard topology.
 
 Loss of keeper nodes (which handle coordination) is more critical than loss of a single database node (which handles storage).
 
 ### VictoriaMetrics
 
-Shows the overall health status of VictoriaMetrics components. Green **Healthy** indicates all components are operational and metrics collection and querying are working properly. Red **Not Healthy** signals the time series infrastructure is degraded.
+Shows VictoriaMetrics instances alive versus expected. The **VictoriaMetrics Components** panel breaks health down by `vmauth`, `vminsert`, `vmselect`, `vmstorage`, and `vmagent`.
 
-VictoriaMetrics uses multiple components working together:

 ### HAProxy
 
-Shows the overall health status of HAProxy load balancer pods. Green **Healthy** means load balancing is working and traffic is properly distributed across your PMM replicas. Red **Not Healthy** means the load balancer has problems and you may not be able to access PMM.
+Shows HAProxy instances alive versus expected. The backend server table reports the UP or DOWN state of each server in each backend.

 ## Dashboard Usage Tips
 
 ### Refresh rate
-This dashboard auto-refreshes every 30 seconds to provide near real-time monitoring.
+Use Grafana's refresh control to update the dashboard while investigating failovers or degraded components.
 
 ### Filters
 Use the namespace and Helm release variables at the top to focus on your specific PMM HA deployment if you have multiple installations.
