Viewing gauge properties Performance Manager monitoring tasks Viewing the size of a performance database

Perform this task to view performance gauge properties for a storage device. Performance Manager gauges are user-defined, graphical and tabular presentations of performance data and performance exceptions.

Prerequisites

Before you can view gauge properties for a storage device, you must create and run a performance data collection task for that device.

Performance Manager supports the following gauge types:

Performance
The performance-type gauges present sample-level performance data. The frequency at which performance data is sampled on a device depends on the sampling frequency that you specify when you define the performance collection task. The maximum and minimum values of the sampling frequency depend on the device type. The static display presents historical data over time. The refreshable display presents near real-time data from a device that is currently collecting performance data.
Exception
An exception gauge is one, real-time occurrence of the condition in which a measurement, derived during collection from values sent by a storage device, exceeds a preset value (either a warning or critical value). For each day in a time span that you select, Performance Manager reports the total number of exceptions of each type for the selected device. (The types of exceptions that are reported depend on the device type.) With an expanded view, you can see information about each exception occurrence such as the time, subcomponent identification, and the actual value of the metric when the exception occurred.
Steps

Perform the following steps to view gauge properties for a device:

  1. From the IBM Director Task pane, click Multiple Device Manager.
  2. Click Manage performance. The performance management tasks are displayed.
  3. Drag the Gauges icon to the Group Content pane. Drop the icon on the device for which you want to view a gauge from a previously created performance data-collection task. The Gauges panel opens.
  4. The Gauges table is displayed.

    The Gauges table provides the following information:

    Gauge Name
    The gauge definition name that you entered when you created the definition.
    Description
    The gauge definition description that you entered when you created the definition.
    Type
    The gauge type that you selected when you created the definition.
    Device
    The device that you selected during the creation of the definition.
    Date modified
    The date the definition was last modified (month, day, year).
  5. Select a gauge in the Gauge table to view its properties.
  6. Click Properties to view or change gauge properties. The properties for the selected gauge are displayed.
  7. To see more details about an exception gauge, select the gauge in the table and click Details. The Exception details panel is displayed.
    Note:Note: The information provided in the Exception details panel is device dependent.

    The Exception details panel provides the following information:

    Gauge name
    The name you assigned to the exception gauge when you created it.
    Description
    The description of the exception gauge that you entered.
    Time
    Time stamp for the data being displayed.
    Threshold name
    The name of the threshold. For example, Disk utilization.
    Level
    Warning or Error.
    Value
    The exception data value.
    Component type
    The information in this field is device dependent.
    Time of last data collection
    The time and date of last data collection. This information comes from Performance Manager.
