Dynamic Trend Views

Dynamic trend views combine data from multiple managed items, or groups of items, in a single view. You can add this view to a dashboard or context page. You can compare the data from hundreds of managed items, or groups of managed items, in one or more charts. View settings let you select display units and determine how data is plotted.

Dynamic trend views combine data from multiple managed items, or groups of items, in a single view. You can add this view to a dashboard or context page. You can compare the data from hundreds of managed items, or groups of managed items, in one or more charts. View settings let you select display units and determine how data is plotted.
These views support only the Data Aggregator data source.
Dynamic trend views let you create a trend chart for a selected metric. The view is termed "dynamic" because it has the following options:
  • Displaying an individual chart for the selected metric for each item that you select.
  • Displaying a single chart for all the selected items, for a single metric.
  • Displaying a single trend line for a selected metric that reflects aggregated data from all the selected items.
Use dynamic views during advanced troubleshooting. These views let you build a complex comparison of data from multiple groups, or a temporary grouping of items. You can quickly select items from across a wide range of possibilities, without creating a group in advance.
For example, you can use dynamic views to analyze data from any of the following items:
  • Multiple interfaces in a group
  • The interfaces in your inventory with the worst performance metrics
  • The interfaces on a single device
A dynamic view is empty until you edit the view settings that you want to apply.
Trend data in dynamic views represents averages of metric values across all items that are included.
Dynamic trend views require more page space than other types of views. To add a dynamic trend view to a dashboard, add it to a single-column area in the layout. Do not add a dynamic trend view to a small section on a dashboard layout.
Dynamic trend views also require more space for the PDF output.
Maintenance indicators apply to all the devices and components in a site group. When the associated site group is selected in the context, maintenance indicators appear as shading in dynamic trend views. For more information, see Schedule Maintenance Indicators.
Dynamic trend views apply a lighter shading to show business hours. For more information, see Configure Business Hours Filtering.

Configure a Dynamic Trend View
To configure a dynamic trend chart, customize or edit a dynamic trend view. Dynamic trend views contain no data until you edit them to select settings.
For standard view configuration details, see Customize Views.
Follow these steps:
  1. Select one of the following Chart Type options:
    • Trend Chart
      View a traditional trend line for each device, component, or metric.
    • Stacked Chart
      View a stacked line on top of each other for each device, component, or metric.
  2. Select one of the following
    Standardized Axis 
    options for the Y-axis of each trend chart:
    • Fixed at 0 to 100
      Maintain a static range, 0 through 100, for the Y-axis.
    • Calculated
      Let the Y-axis adjust dynamically, based on the range of metric values that are included. The calculated setting is applied to all charts in the view.
    • Scale per Chart 
      Let the Y-axis adjust dynamically, based on the range of metric values for each chart in the view. The Y-axis scaling of one chart in a view does not affect the scaling of any other chart.
  3. Optionally, enable
    Baseline Metrics
    .
    The baseline trend line lets you determine whether utilization trends are changing. The baseline data
     
    that is plotted in many views shows statistical deviations from "normal" performance for a given statistic. For more information, see Baseline Calculations.
  4. If you are adding the dynamic trend view to a dashboard, set the 
    Context
     to 
    Dynamic
     or 
    Fixed
    .
    • Dynamic
      A Dynamic context indicates that the context of the view changes with the context of the dashboard page. 
    • Fixed
      A Fixed context indicates that the view uses a specified group, device, or component as a context for the data.
