Image performance
On the Images tab, you see the lists of top images by throughput and latency, and the performance charts. The layout is similar to the Pools tab, and if the domain has no images, the lists and charts are shown empty.
Images tab
The Images tab shows top lists for highest throughput and highest latency, along with IOPS, throughput, and latency charts. If the domain has no images, "No images found" and "No data available" are shown.
| No. | Feature | Item | Description |
|---|---|---|---|
| 1-1 | Highest throughput | Highest throughput | · The top list of images with the highest throughput (image name and throughput). |
| 1-2 | Highest latency | Highest latencies | · The top list of images with the highest latency (image name and latency). |
| 1-3 | Performance charts | IOPS · Throughput · Average latency · Highest IOPS | · Charts for image IOPS, throughput, average latency, and highest IOPS follow ("No data available" when there is no data). |
Chart actions
From the more button (⋯) on each chart, you can use Download image (PNG), Download CSV, and View data (data table), and you can enlarge a chart with the expand button (⤢). Changing the period in the expanded modal does not affect the original screen.
