Viewing saved background performance monitor data

The physical disk or network location that contains the saved performance data file, must contain some free space, otherwise the file will not load. A background performance monitor graph plots a single performance metric over time for up to five objects. The x-axis of the graph represents time. The y-axis of the graph represents the metric value. The metric value is displayed in thousands (K), when the value exceeds 99,999, starting with 100 K until the number reaches 9999 K, then the value is displayed in millions (M). For amounts greater than 9999 K but less than 100 M, the value is displayed in tenths (for example, 12.3 M).
  1. In the Array Management Window (AMW), click the Performance tab.
  2. Click the Launch background performance monitor link.
    The View Current Background Performance Monitor dialog is displayed.
  3. Click the Launch saved background performance monitor link.
    The Load Background Performance dialog is displayed.
  4. Navigate to the .csv file that you want to open, and then click Open.
    The View Saved Background Performance Monitor dialog opens.
  5. In the Select metric drop-down list, select the performance data that you want to view.
    You can select only one metric at a time.
  6. In the Select an object(s) list, select the objects for which you want to view background performance data.
    You can select up to five objects to monitor on one graph. Use Ctrl-Click and Shift-Click to select multiple objects. Each object is plotted as a separate line on the graph. The graph shows all of the data points in the saved file.   
    NOTE: If you do not see a line that you defined on the graph, it might be overlapping another line.
  7. (Optional) To change the time period plotted on the graph, make selections in the Start Date, Start Time, End Date, and End Time drop-down lists.
  8. To close the dialog, click Close.
