Cause

The Hardware Health Chart is trying to load a display label that is missing. When that label cannot be found, the Group Details page will fail to load.

This does not mean the monitored device is down. It also does not mean all Hardware Health polling has stopped. The issue is limited to displaying the Hardware Health Chart on the affected Group Details page.

Resolution

Workaround

If the Hardware Health Chart must remain on the Group Details page, you can use this workaround. This needs to be done on the SolarWinds server where the website is being hosted, Primary Poller, and/or all Additional Web Servers.

The update is made in this file(Default Location):

C:\Program Files\SolarWinds\Orion\Web\Orion\HardwareHealth\Resources\Hardware\TreeTemplates\CategoryGroupedProviderForGroup.html

Locate this entry:

<td class="hardwareTree-header-column hardwareTree-header-on" width="20%">@{R=HardwareHealth.Strings;K=HHLIBCODE_DOY_10; E=js}</td>

Replace it with this entry:

<td class="hardwareTree-header-column hardwareTree-header-on" width="20%">@{R=HardwareHealth.Strings;K=CiscoCefcFRUPowerOperStatus_On; E=js}</td>

On the SolarWinds Server using the SolarWinds Service Manager, restart the SolarWinds NetPerfMon website.

Refresh the Group Details page, and it should now load:
