Overview

Example errors:

  • The "Search by Endpoint " resource is missing. The file \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\SearchEndpoints.ascx is not found.

  • The "Search by Application/Port " resource is missing. The file \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\SearchApplications.ascx is not found.

  • The "Traffic View Builder " resource is missing. The file \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\NetFlowCustomFilter.ascx is not found.

  • The "Top XX Applications " resource is missing. The file \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\TopApps.ascx is not found.

  • The "Top XX Endpoints " resource is missing. The file \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\TopXXEndpoints.ascx is not found.

  • The "Top Conversations " resource is missing. The file \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\TopConversations.ascx is not found.

NTA collection and other modern NTA resources continue to work. The impact is limited to these legacy UI widgets.

Affected Components

  • NetFlow Traffic Analyzer (NTA):

    • Deployed and licensed

    • NTA flows confirmed on APE / collector

  • Primary web server / MPE:

    • Hosts SolarWinds web console

    • NTA installed/selected in the Platform Installer

Symptoms

On NTA Summary:

  • Red error blocks instead of NTA widgets:

    • Search by Endpoint

    • Search by Application/Port

    • Traffic View Builder

    • Top XX Applications

    • Top XX Endpoints

    • Top Conversations

  • Error text explicitly references missing .ascx under:

    • \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\

    • \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\

Product section

Netflow Traffic Analyzer

Cause

Root Cause

  • The following legacy UI resources are effectively retired and are no longer deployed on clean/updated installs:

    • \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\SearchEndpoints.ascx

    • \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\SearchApplications.ascx

    • \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\NetFlowCustomFilter.ascx

    • \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\TopApps.ascx

    • \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\TopXXEndpoints.ascx

    • \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\TopConversations.ascx

  • The default NTA Summary view definition still references those resources.

  • As a result, after upgrade:

    • The .ascx files are not present on the web server.

    • The Summary view continues to try to render those resources.

    • The web console shows “resource is missing / .ascx is not found” instead of silently hiding them.

Resolution

Prerequisites and Warnings

  • You must have SQL access to the SolarWinds Platform database.

  • Ensure there is a recent full backup of the SolarWinds Platform database.

  • Changes below affect only the [dbo].[Resources] table:

    • No schema changes

    • Fully reversible via the backup copy

Step 1 – Identify the legacy NTA resources

Run:

-- Scripts are not supported under any SolarWinds support program or service.
-- Scripts are provided AS IS without warranty of any kind. SolarWinds further
-- disclaims all warranties including, without limitation, any implied warranties
-- of merchantability or of fitness for a particular purpose. The risk arising
-- out of the use or performance of the scripts and documentation stays with you.
-- In no event shall SolarWinds or anyone else involved in the creation,
-- production, or delivery of the scripts be liable for any damages whatsoever
-- (including, without limitation, damages for loss of business profits, business
-- interruption, loss of business information, or other pecuniary loss) arising
-- out of the use of or inability to use the scripts or documentation.

SELECT ResourceID, ResourceName, ResourceFile
FROM [dbo].[Resources]
WHERE ResourceFile LIKE '%NetFlowTrafficSummary%SearchEndpoints%'
   OR ResourceFile LIKE '%NetFlowTrafficSummary%SearchApplications%'
   OR ResourceFile LIKE '%NetFlowTrafficSummary%NetFlowCustomFilter%'
   OR ResourceFile LIKE '%NetFlowTopXXSummary%TopApps%'
   OR ResourceFile LIKE '%NetFlowTopXXSummary%TopXXEndpoints%'
   OR ResourceFile LIKE '%NetFlowTopXXSummary%TopConversations%';

You should see rows whose ResourceFile ends with the six legacy paths:

  • \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\SearchEndpoints.ascx

  • \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\SearchApplications.ascx

  • \Orion\TrafficAnalysis\Resources\NetFlowTrafficSummary\NetFlowCustomFilter.ascx

  • \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\TopApps.ascx

  • \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\TopXXEndpoints.ascx

  • \Orion\TrafficAnalysis\Resources\NetFlowTopXXSummary\TopConversations.ascx

Verify that:

  • No other, unrelated resources are matched.

  • Resource names correspond to the legacy widgets (Search by Endpoint, Search by Application/Port, Traffic View Builder, Top XX Applications, Top XX Endpoints, Top Conversations).

Step 2 – Remove the legacy resources

Once confirmed, run:

-- Scripts are not supported under any SolarWinds support program or service.
-- Scripts are provided AS IS without warranty of any kind. SolarWinds further
-- disclaims all warranties including, without limitation, any implied warranties
-- of merchantability or of fitness for a particular purpose. The risk arising
-- out of the use or performance of the scripts and documentation stays with you.
-- In no event shall SolarWinds or anyone else involved in the creation,
-- production, or delivery of the scripts be liable for any damages whatsoever
-- (including, without limitation, damages for loss of business profits, business
-- interruption, loss of business information, or other pecuniary loss) arising
-- out of the use of or inability to use the scripts or documentation.

DELETE FROM [dbo].[Resources]
WHERE ResourceFile LIKE '%NetFlowTrafficSummary%SearchEndpoints%'
   OR ResourceFile LIKE '%NetFlowTrafficSummary%SearchApplications%'
   OR ResourceFile LIKE '%NetFlowTrafficSummary%NetFlowCustomFilter%'
   OR ResourceFile LIKE '%NetFlowTopXXSummary%TopApps%'
   OR ResourceFile LIKE '%NetFlowTopXXSummary%TopXXEndpoints%'
   OR ResourceFile LIKE '%NetFlowTopXXSummary%TopConversations%';

Notes:

  • This only removes the resource definitions from the global Resources catalog.

  • Any views that reference them will no longer be able to render them.

  • No changes are made to other NTA resources or to NTA data.

Step 3 – Verify in the Web Console

  1. Log in to the SolarWinds web console.

  2. Navigate to NetFlow Traffic Analyzer Summary.

  3. Confirm:

    • The red error blocks for:

      • Search by Endpoint

      • Search by Application/Port

      • Traffic View Builder

      • Top XX Applications

      • Top XX Endpoints

      • Top Conversations
        are no longer present.

    • Other NTA widgets and data still load successfully.
