Description

This dashboard monitors a Longhorn storage cluster, aggregating node, disk, and volume health and capacity metrics to provide a holistic view of cluster status. It highlights key indicators such as longhorn_node_count_total, longhorn_volume_state, and longhorn_disk_capacity_bytes to track total nodes, health/robustness of volumes, and disk capacity utilization, respectively. Key features include per-node storage usage vs. capacity, volume health distribution (healthy, degraded, fault), and attached/detached volume counts for quick operational insight.
