PDFPerformance metrics for NFS
View historical performance metrics
- Under System, select Performance.
- Select the historical metrics dashboard for the system for which you created a performance metrics display.
- For each system dashboard, you can define the time range of the values displayed for all the metric line charts on that dashboard. The default time range is Last 1 hour. Alternatively, select one of the other time range values.
The time range selections are enabled only if Unisphere has data spanning that time range.
- For a custom time range, select Custom and choose the start and end dates and times of the charts displayed. Click OK.
- To drill down into the data displayed in the line chart, you can breakdown the data displayed into individual lines that show the categories and contributors that provide data to the performance metric. Choose among the breakdown categories available for a particular metric.
Each contributor displays as a different color line in the chart and is identified in the legend. You can quickly remove and add each contributor by clicking on its name in the legend. Use the breakdown display to determine if one contributor is adding to the aggregated total more than another contributor as well as analyze how a contributor's activity increases or decreases at a particular time.
- Hover over a data point in the chart to display the date, time, and measurement associated with that data point. Gaps in metric data collection are displayed as gaps in the line chart.
- For object-level line charts, such as those for LUNS, file systems, drives, and so forth, you can select Percentage View to view the data points as percentage values instead of absolute values.
