Cluster Health
A simplyblock cluster consists of interconnected management nodes (control plane) and storage nodes (storage plane) working together to deliver a resilient, distributed storage platform. Monitoring the overall health, availability, and performance of the cluster is essential for ensuring data integrity, fault tolerance, and optimal operation under varying workloads. Simplyblock provides detailed metrics and status indicators at both the node and cluster level to help administrators proactively detect issues and maintain system stability.
