Reporting › Router Context Views › Availability Trend

Availability Trend

The Availability Trend with Events view shows you a trend chart of average availability values from the indicated device over the selected time period. If available, events are shown as flags to indicate the times when events were reported.

This view displays the calculated baseline average. The way the baseline is calculated varies by the registered data source. This view also displays a projection of the average values for time periods of one week or more.

By default, the Availability Trend with Events view includes the following information:

Device

Identifies the device whose data is reflected in the view. If an administrator defined an alias for the device item, the alias is displayed. Otherwise, the discovered device name is displayed.

Average Availability

The average availability of the device, plotted as an average of the following values:

• 0: Unavailable
• 100: Available

Note: Unavailability is calculated by subtracting the average availability from 100.

Edit Trend View Settings

You can change several settings for a trend chart view. In addition to providing a new title, you can show or hide some of the trend lines and select another managed item context for the data. Trend views support the Zoom feature for time frame selection.

Follow these steps:

1. Click the Options (gear) icon on the view, and select Edit from the menu.

   The view Settings dialog opens.

2. Change the view Title or Subtitle to reflect the modified view.
3. Select Show or Hide from the drop-down menus to control the display of any of the following trend lines or data points in the chart:
   • Projection - The line that plots projected average values for twice the current time period.
   • 95th Percentile - The line that plots the values in the top 5% of all measurements that were taken during the reporting interval.
   • Events - The data points that show when events were reported during the reporting interval.
   • Goal Line - The line that plots the value you selected as the goal for the metric in this view.

   Note: Not all trend line options are available for all trend chart types.

4. Set a value for the Goal Line if you selected to show it.

   Goal lines serve as visual indicators of fixed metric values. For example, select a value within range of a critical threshold so that you can determine at a glance whether performance is approaching a degraded level.

5. Supply a label for the Goal Line to identify the value you selected.
6. Click to select another Resolution setting. The resolution is the amount of time that each data point in the chart represents.

   Default: 5 minutes. Select a one-minute, ten-minute, or 15-minute resolution.

7. Click to select another managed item in the Context Settings area.

   Data from the new item will be shown in the view.

8. Select the scope of your changes from the Apply Changes drop-down. Select one of the following options:
   • For All Tenant Users: Saves the changes so that they are only available to users associated with your tenant (possibly the Default Tenant).
   • My User Account: Saves the changes to your user account as a default for this view.
   • My Current Session: Reverts the changes when you log out.

   Note: The availability of these options depends on your user account role rights.

9. Click Save.

   The view is refreshed to reflect your updates.
