View graphical performance data

Contributors netapp-jolieg

You can view graphical performance data for logical objects, physical objects, applications, and workloads.

About this task

The performance graphs show historical data as well as live data currently being captured. A vertical line on the graph, labeled Live updating, distinguishes historical data from live data.

Home page view

The Home page contains a graph showing storage array level performance. You can select limited metrics from this view, or you can click View Performance Details to select all the available metrics.

Detailed view

The graphs available from the detailed performance view are arranged under three tabs:

  • Logical View — Displays performance data for logical objects grouped by volume groups and pools. Logical objects include volume groups, pools, and volumes.

  • Physical View — Displays performance data for the controller, host channels, drive channels, and drives.

  • Applications & Workloads View — Displays a list of logical objects (volumes) grouped by the application types and workloads you have defined.

Steps

  1. Select Home.

  2. To select an array-level view, click the IOPS, MiB/s, or CPU button.

  3. To see more details, click View Performance Details.

  4. Select Logical View tab, Physical View tab, or Applications & Workloads View tab.

    Depending on the object type, different graphs appear in each tab.

  5. Use the options to view the objects and information you need.

    Options
    Options for viewing objects Description

    Expand a drawer to see the list of objects.

    Navigation drawers contain storage objects, such as pools, volume groups, and drives.

    Click the drawer to view the list of objects in the drawer.

    Select objects to view.

    Select the check box to the left of each object to choose the performance data you want to view.

    Use Filter to find object names or partial names.

    In the Filter box, enter the name or a partial name of objects to list just those objects in the drawer.

    Click Refresh Graphs after selecting objects.

    After selecting objects from the drawers, select Refresh Graphs to view graphical data for the items you have selected.

    Hide or show graph

    Select the graph title to hide or show the graph.

  6. As needed, use the additional options for viewing performance data.

    Additional options
    Option Description

    Time frame

    Select the length of time you want to view (5 minutes, 1 hour, 8 hours, 1 day, 7 days, or 30 days). The default is 1 hour.

    Note Loading performance data for a 30-day time frame can take several minutes. Do not navigate away from the web page, refresh the web page, or close the browser while data is loading.

    Data point details

    Hover the cursor over the graph to see metrics for a particular data point.

    Scroll bar

    Use the scroll bar below the graph to view an earlier or later time span.

    Zoom bar

    Below the graph, drag the zoom bar handles to zoom out on a time span. The wider the zoom bar, the less granular the details of the graph.

    To reset the graph, select one of the time frame options.

    Drag and drop

    On the graph, drag the cursor from one point in time to another to zoom in on a time span.

    To reset the graph, select one of the time frame options.
