Views by Device Type Page Fails to Load in SolarWinds Platform

Overview

In some environments, navigating to Settings > All Settings > Views by Device Type may fail to load and eventually times out after approximately two minutes.

The page may remain stuck on a loading spinner or return a timeout message.

In the OrionWeb.log, a timeout similar to the following may appear:

 

ERROR System.Web.HttpException: Request timed out.
Request: /Orion/Admin/ViewsByDeviceType.aspx
Duration: 119635ms

 

In Orion.InformationService.log, a long-running SWIS query may be observed, for example:

 

INFO SWIS query execution completed.
Duration: 141502ms
Query: <long SWIS query selecting Node, NodeSettings, Custom Properties, etc.>

 

Other symptoms:

  • Page continuously loads without completing.
  • Page eventually throws a timeout after ~120 seconds.
  • Increased database load when the page is accessed.
  • No other pages appear impacted.

 

This issue is more commonly encountered in environments with large device counts or extensive use of custom properties.

Cause

The issue is caused by an inefficient internal SWIS query used by the legacy Views by Device Type page.

The query retrieves:

  • All columns from the Nodes table
  • All NodeCustomProperties
  • All NodeSettings
  • Additional joined metadata

…and then sorts the results by a non-indexed column.

This results in:

  • Very large datasets being returned
  • Slow server-side processing
  • Long query execution times
  • Timeouts before the page finishes loading

Because this logic is part of an internal shared component used across the platform, the issue cannot be addressed through configuration changes.

Resolution

Upgrade the SolarWinds Platform to version 2026.1.
