Performance views

Gain insights into the performance of the resources that are monitored in your storage environment. You can use performance metrics for volumes, disks, or ports to help you measure, identify, and troubleshoot performance issues and bottlenecks in storage systems.

On the Performance page, performance metrics for storage systems are displayed in a chart and related information for all storage systems is displayed in the performance chart legend.

By default, the 10 storage systems with the highest overall total I/O rate over a 12-hour period are displayed in the chart. These storage systems are listed under Resources on the left and are highlighted at the top of the performance chart legend, which is sorted by the Total I/O Rate - overall (ops/s) column.

The performance information is displayed in the following format:

Viewing Performance Information
The performance information can be viewed in a line graph (default) and a table format. Users can switch between these modes as needed.Chart icon
Chart icon Line Graph (Default)
  • The line graph visually represents storage system performance trends over time.
  • The y-axis indicates the unit of measurement for each metric, while the x-axis represents time.
  • Each line on the graph represents a metric and a storage system. For example, selecting two metrics and three storage systems will display six lines on the graph.
  • To view a snapshot of performance information at a specific time, hover the mouse pointer over points on a line in the graph.
Table icon Table Format
  • The table displays performance information for the storage systems.
  • Each row represents a storage system and a timestamp. For example, if a graph has six data points during the selected time range, there will be six rows for each storage system in the table.
  • Each metric is displayed as a column in the table.
  • To view additional metrics and information for a storage system, right-click anywhere in the header row of the table and select "extra column".
Performance chart legend
The bottom section of the performance view is a table that shows more information about the storage systems. Each row represents a storage system, and each column provides extra asset and performance information about the storage system.
