Below is a detailed description of each area.
Inventory
Displays the total count of resources in the cluster as cards.
| Item | Description | Target screen |
|---|---|---|
| Pools | Number of storage pools | Pools |
| Hosts | Number of host servers | Hosts |
| OSDs | Number of OSDs | OSDs |
| Buckets | Number of buckets | Buckets |
| Objects | Total number of objects | — |
Clicking each card navigates to the list screen for the corresponding resource.
Capacity
Displays the usage ratio against total RAW capacity as a Usage chart.
| Range | Bounds | Meaning |
|---|---|---|
| Safe | 0–69% | Normal |
| Warning | 70–89% | Capacity caution |
| Danger | 90%+ | Capacity shortage warning |
Warning
When usage exceeds 70% the legend color changes to Warning, and when it exceeds 90% it changes to Danger.
Cluster Utilization
All charts are displayed as time-series line charts. Use the monitoring toolbar at the top to set the data query range for all charts.
| Chart | Description | Series | Unit |

| OPS | Client IOPS | Reads, Writes | ops/s |
| Client Throughput | Read/write throughput | Reads, Writes | B/s (auto-converted) |
| OSD Latencies | OSD Apply/Commit latency | Apply, Commit | ms |
| Requests/sec | Requests per second | Requests/sec | req/s |
| Recovery Throughput | Recovery and rebalancing throughput | Recovery Throughput | B/s (auto-converted) |
| Latency (Client/HTTP) | Client response latency | GET, PUT | ms |
Chart features
The more (⋮) button on each chart provides the following features.
| Feature | Description |
|---|---|
| Download image | Save the chart as a PNG image (file name: {chart_name}_{YYYYMMDD}_{HHMM}.png) |
| Download CSV | Export the time-series data as CSV (based on the monitoring toolbar time range) |
| View data | Open a drawer that shows the chart data as a table |
Clicking a chart opens an expanded modal, where you can adjust the time range separately.
