Monitoring Overview

MASS provides built-in monitoring through the Dashboard. No external tools are required to observe cluster health, storage performance, and hardware status.

Dashboard Panels

Section	What it shows
Overview	Cluster health summary, active nodes, total and used capacity
Hardware	Per-node NVMe drive health, fan and PSU status
Analysis	Throughput, IOPS, and latency trends per VolumeGroup and Volume
Storage	Capacity usage breakdown by VolumeGroup with expansion indicators

Navigate to each section from the left navigation bar. Use the time range selector in Analysis to review historical performance trends.

Alerts and Notifications

When a storage node, drive, or VolumeGroup enters a degraded or failed state, an alert badge appears in the Dashboard header. Click the badge to see the active alerts and recommended actions.

For proactive monitoring, configure email or webhook notifications in Settings → Notifications.
