Configure a Heatmap Widget

A Heatmap widget allows users to view statistics for managed, failed, and unresolved devices or device groups relating to the following parameters:
  • CPU Utilization - Total usage of CPU in percentage along with the unused CPU limit
  • Memory Utilization - Used memory space in percentage
  • Bandwidth Utilization - Total bandwidth limit along with the used bandwidth percentage
  • Device Information - Statistical information including expiry date, vendor, version, and uptime
  • Alarms - All alerts corresponding to each device included in the heatmap
  • Logs - All logs corresponding to each device included in the heatmap
  • Graph - Displays the current connections for each device included in the heatmap
  • iHealth reports (F5 devices only)

In the Heatmap widget, ADC device groups appear as color-coded blocks, with the colors representing the following:

  • Green - All devices in the group are healthy
  • Red - At least one device in the group is in a critical state
  • Gray - Statistics have not been collected for the device group.
  • Orange - One or more devices in the group have reached a warning limit

To configure a Heatmap widget on your dashboard, complete the following steps:

  1. If you are creating a Heatmap widget as part of creating a new dashboard, complete the steps in theCreate a Dashboard topic above, then jump to Step 5 below. If you are creating a Heatmap widget for an existing dashboard, click in the Command bar of the dashboard.
  2. On the Create widget screen that pops up, select Custom as the widget type.
  3. Enter a name for the widget.
  4. In the Basic charts field of the Settings screen, click the Heatmap option.
  5. In the Filter query field, click the groups you want to include in the heatmap.
  6. Click Next.
    A Heatmap widget configuration screen appears.
  7. In the Configure field, select the Groups or Devices radio button depending on whether you want the heatmap to show data for device groups or individual devices.
  8. In the Select field, click the dropdown arrow and select each of the groups or devices you want to include in the heatmap.
  9. In the Time interval field, select the frequency that you want the system to check the utilization levels of the devices or groups you selected in Step 7.
  10. In the CPU Utilization field, click and drag the sliders to define the safe, warning, and critical value limits for device CPU.
  11. In the Memory Utilization field, click and drag the sliders to define the safe, warning, and critical value limits for device memory.
  12. In the Bandwidth Utilization field, click and drag the sliders to define the safe, warning, and critical limits for device bandwidth.
  13. When you are done configuring the heatmap settings, click Save.
    The heatmap widget then displays on the dashboard, with separate, color-coded blocks representing the following for each of the devices or groups you selected.
    • Green - CPU, memory, or bandwidth usage within safe limits.
    • Orange - CPU, memory, or bandwidth usage within warning limits
    • Red - CPU, memory, or bandwidth usage within critical limits
    • Gray - Missing or no information for the related group or device
    On hovering your cursor over a device or group, the following information appears in a popup tooltip:
    • Current CPU utilization for the device/group
    • Current bandwidth utilization for the device/group
    • Current memory utilization for the device/group
