MinIO AIStor — Executive overview. Single-screen non-technical cluster health: headline server/drive KPIs, raw and usable capacity (pie charts + utilisation gauge), performance and error KPIs, TTFB latency distribution across six buckets, and trend timeseries for capacity / throughput / request rate / errors. Each stat tile carries a sparkline showing the last 12h trend.

MinIO AIStor — Bucket-event notifications. Send rate, errors, skipped events, per-target queue health and in-flight concurrency. Empty until at least one notification target (webhook, NATS, Kafka, etc.) is configured.

MinIO AIStor — Cluster overview. Capacity, health, usage, top buckets, erasure-coding configuration, license status. Cross-links to per-subsystem cluster dashboards.

MinIO AIStor — Healing. Heal-engine activity, error rates, lock contention, and debug counters that track manual-intervention / undecided / transitioned cases. A healthy cluster shows near-zero heal rate and no errors.

MinIO AIStor — API overview. Day-to-day request-path health: rate, errors, latency, concurrency, per-server distribution. Drill into the linked dashboards for per-bucket, QoS, and RDMA detail.

MinIO AIStor — System overview. Node-level CPU load and breakdown, memory composition, process resident memory, FDs, threads, goroutines, and process I/O.

MinIO AIStor — Drive SMART health. NVMe endurance + spare, estimated failure risk, power-on lifetime, and MegaRAID physical-drive counters. Pair with the Drives dashboard for I/O-side metrics.

MinIO AIStor — IAM. Identity-data sync between nodes, LDAP IDP connectivity, and authentication-plugin health. Empty rows are normal when LDAP / external auth plugin are not configured.

MinIO AIStor — API per-bucket. Drill into individual buckets: requests, errors, traffic, latency, concurrency, cancellations.

MinIO AIStor — Batch jobs. Cluster-wide batch-job state (in-progress/completed/failed) split by type (replicate, expire, keyrotate, catalog), plus per-bucket object-level batch metrics.

MinIO AIStor — Drives. Throughput, IOPS, latency, errors, capacity, API latency, corruption/healing, and SMART status. Filter by server and drive via the dropdowns.

MinIO AIStor — Site replication. Cluster-wide replication throughput, queue depth, errors, retries, proxied requests, plus per-server worker metrics, link health, and SLA tracking. Cluster-wide panels populate when site replication is configured; per-server worker panels populate immediately.

MinIO AIStor — Cluster Erasure Sets. Per-(pool, set) health, online/healing drive counts, read/write quorum tolerance, and per-drive shard health. Designed to scale from lab clusters (8–16 drives) to production (100+ drives) — top rows summarise cluster-wide and per-set state at a glance; the per-drive shard table is sortable and filterable so it stays readable at high drive counts.

MinIO AIStor — Scanner. Background scan rate (objects/versions/directories), bucket-scan progress, and excess-data detection. The scanner runs continuously; an idle cluster still produces small but non-zero rates.

MinIO AIStor — System trends. The `_avg` / `_max` smoothed companions MinIO emits alongside its instant CPU / memory / network metrics. Useful for long-term capacity-planning views where Prometheus's own rate / avg_over_time would add noise.

MinIO AIStor — KMS. KMS connectivity, request rate, success vs failure breakdown, latency distribution, per-server uptime.

MinIO AIStor — API diagnostics. Top-5 timeseries + per-server distribution barcharts for request rate, errors and traffic; cumulative TTFB latency histogram across 8 buckets; rejected-request breakdown by reason. Use alongside api/overview and api/qos when investigating uneven load or rising error rates.

MinIO AIStor — Bucket replication. Throughput, failures, latency, proxied requests, credential errors. Filter by bucket and target ARN.

MinIO AIStor — Audit. Delivery health for configured audit targets (webhooks, files, syslog). Most panels are empty until at least one audit target is configured.

MinIO AIStor — System diagnostics. Top-5 timeseries paired with per-server distribution barcharts for CPU, memory, goroutines, drive throughput, and internode network. Use this dashboard when the operational system/* dashboards report cluster-wide pressure and you need to find which servers are responsible.

MinIO AIStor — Cluster diagnostics. Per-pool drive usage and health tables, plus per-server drive count summary. Use alongside cluster/overview and cluster/erasure-set when investigating capacity skew, drive failures, or node-level drive loss.

MinIO AIStor — Network. Internode connectivity (peers, throughput, RTT, reconnects, queues), per-NIC RX/TX bytes and errors, and TLS-certificate expiration tracking.

MinIO AIStor — ILM (Information Lifecycle Management). Expiry + transition workers, action breakdown, pending queues, missed events, per-tier transition totals. Most panels stay near zero on a cluster without lifecycle rules configured.

MinIO AIStor — Network. Internode connectivity (peers, throughput, RTT, reconnects, queues), per-NIC RX/TX bytes and errors, and TLS-certificate expiration tracking.
