Nodes missing from the NCM Configuration Management View

Overview

The NCM nodes are not visible in the Configuration Management tab after upgrading to NCM 7.3 or later. Nodes are showing in an NCM desktop application and in the NCM Summary view but they remain to be missing in the Configuration Management view. 

 

Note: NCM desktop application is discontinued from NCM 7.4

Environment

  • NCM 7.3 and later

Cause

Custom properties that are common to default NCM properties cause the schema to be corrupted and nodes cannot be displayed.

Sample Information Service log: (C:\ProgramData\Solarwinds\InformationService\v3.0)

2014-06-16 17:21:42,779 [6] ERROR SolarWinds.InformationService.Core.InformationService - Exception caught in method RunQuery
SolarWinds.Data.Query.ParserException: Ambiguous column name VirtualMachine between entities Orion.Nodes and Orion.NodesCustomProperties.

Resolution

Based on the sample logs above, you have a node custom property called Virtual machine and it is breaking the NCM query. To resolve this you can simply delete offending Custom Property:

  1. Log in to your Orion Web Console using admin account
  2. Go to Settings
  3. Go to Manage Custom Properties
  4. Find offending Custom Property (in example VirtualMachine)
  5. Select it
  6. Click on Delete and confirm deletion

 

In order to retain current Custom Property values refer to Change the Custom Property name.

 

Note:

  • Make sure that the Custom Property names do not use common terms found in the database such as router, engine, switch, IP and so on.
