Cause

This error occurs because the process tracker in Netwrix Change Tracker is enabled in the policy template, but no specific processes are configured for tracking. The agent cannot execute the tracker poll task without at least one process defined.

Resolution

Edit the policy template assigned to the affected device(s) and either add processes to track or disable the process tracker.

1. Log into Netwrix Change Tracker
2. Navigate to Devices
3. Select the device experiencing the error
4. Select the policy template that is causing the issue (devices can have multiple templatesd assigned, so select the template(s) where the "Processess and Services" tracker is enabled)
5. Select "Processess and Services" tracker
6. To resolve the issue: 6a. Uncheck the Track processes and services in this template box OR 6b. Add at least one service to be tracked.
