Rolling-Log Fix: "ERROR AgentTaskRunner - Task Execution Failed for Task - DeviceConfigTask. Item Wildcards Match Text Must Not Contain Separator"

This article explains how to resolve a Rolling-Log error caused by a misconfigured custom path-match definition in a Netwrix Change Tracker policy template.

Symptom​

The following error appears in the agent Rolling Log:

2018-08-25 12:04:35,780 [9] ERROR AgentTaskRunner - task execution failed for task 2 - DeviceConfigTask-1869
NNT.Agent.Utils.ContainerItemMatch+ContainerItemMatchException: item wildcards match text must not contain separator '\' for MatchType.Wildcards unless ContainerMatchAppliesToWholePath is true.
   at NNT.Agent.Utils.ContainerItemMatch.ValidateMatchPattern(String element, String matchPattern, MatchType matchType, String separator, Boolean containerMatchAppliesToWholePath)
   at NNT.Agent.Utils.ContainerItemMatch..ctor(String rootContainer, Boolean skipRootContainer, String separator, Boolean caseSensitive, Nullable`1 recursionLevels, MatchType containerMatchType, String containerMatchPattern, Boolean containerMatchAppliesToWholePath, MatchType itemMatchType, String itemMatchPattern)
   at NNT.Agent.Core.Tracking.FileSystem.FileSystemTrackerConfigurationCreator.ProcessDeviceConfiguration(DeviceConfiguration deviceConfiguration, IDevice device, String trackerName)
   at NNT.Agent.Core.Tasks.DeviceConfigTask.ApplyDeviceConfigAction(ILifetimeScope scope, IDevice device, DeviceConfiguration configuration, Nullable`1 latestConfigDateUtc)
   at NNT.Agent.Core.Tasks.DeviceConfigTask.Execute(AgentTaskQueue queueContext)
   at NNT.Agent.Core.Application.AgentTaskRunner.ExecuteTask(Int32 runnerId, IAgentTask task, DateTime nowUtc, AgentTaskQueue queue)

Cause​

The agent cannot process an item within the advanced custom path-match definition because the match type is set to Wildcards but the match pattern contains regex syntax (or vice versa).

Resolution​

If you are receiving this error, the agent may not be reporting to your hub. This is a critical error and monitoring will not continue until it is resolved.

  1. Log into the Netwrix Change Tracker console.
  2. Locate the agent presenting this error and go into each of the policy templates assigned to that agent. Inspect the custom path matches for misconfiguration.
  3. Once you have identified the problem template, modify or remove the custom path-match definition that is causing the issue. For example, change the match type from Wildcards to Regex if the pattern contains regex syntax.
  4. Save the policy template.
  5. Check the agent to confirm it has received the new configuration.
