Updated 10/17/17

Fixed issues

This hot fix addresses the issue where SolarWinds Information Service V3 crashes with the following exception: 

   System.NotSupportedException: Implementation doesn't support relationships with multiple column keys.
      at SolarWinds.Data.Providers.SEUM.v3.SEUMAccountLimitationsAddon.SetupRelationships(ISchema schema)
      at SolarWinds.Data.Providers.SEUM.v3.SEUMAccountLimitationsAddon.ApplyLimitationsToEntities(ISchema schema, ISelectStatement select, IIdentity identity)
      at SolarWinds.Data.Providers.Orion.AccountLimitations.LimitationAddonManager.ApplyLimitationsToEntities(ISchema schema, ISelectStatement select, IIdentity identity)
      at SolarWinds.Data.Query.Processor.LimitationApplicator.Process(SelectStatement statement, PreProcessorState state)
      at SolarWinds.Data.Query.Processor.PreProcessor.Process(SelectStatement selectStatement, PreProcessorState& preProcessorState)
      at SolarWinds.Data.Query.Engine.QueryProcessor.ProcessInternal(String query, IQueryExecutionContext context)
      at SolarWinds.InformationService.Core.QueryPlanCache.GetQueryPlan(String query, String usernam...).

This exception is caused because the WPM 2.2.1 Information Service V3 plugin, SolarWinds.Data.Providers.SEUM.v3.dll, is not compatible with Core 2017.1 or newer versions.


  • This hot fix requires main installation of the Web Performance Monitor (WPM) 2.2.1.

  2. Backup the following file to a folder outside of the Orion folder structure. * SolarWinds.Data.Providers.SEUM.v3.dll The default location for this file is in the C:\Program Files (x86)\SolarWinds\Orion\Information Service\3.0\Plugins\ directory.
