Trend reports are designed to show you various storage trends over time.

Each trend report is designed to show you two sets of data taken from two important sources. You’ll notice each chart has two Y axes. The positioning and color for these charts is intentionally the same on all our reports. The blue lines represent Input Output Operations Per Second (IOPS) which is measured as a count. We’re counting the number of operations that happen every second. The solid line represents your overall statistics for performance across your enterprise. The dashed line represents the same statistic, but focuses on your tier 1, your fastest storage. We would always expect the dashed line to be well below the solid line for the same metric. The corresponding Y axis is on the 👈 left side and is labelled IOPS. Again, IOPS is a count, so you are looking for numbers here in the hundreds of thousands.
The second set of lines in green represent the other measure for performance, your system’s latency. Latency is the average time it takes for an I/O request to complete. These statistics are graphed with green lines. As with IOPS, the solid line represents your overall latency and the dashed line surfaces your tier 1 performance. The Y axis for this set of statistics is on the right side 👉 , and its labelled using a measure of time in milliseconds.
