N-central Help

System Change service

The System Change service monitors the hardware components discovered on a Windows device. Once SolarWinds N-central discovers these components, it creates a snapshot of this asset information. The System Change service uses this snapshot as a baseline to monitor any changes that occur in the assets of the device. The service scans the device for changes every day at 9:00 am. For example, the removal of a network adapter at 1:00 pm is reflected in the state of the service at 9:00 am the next day. This change is also reflected in the updated snapshot, which can then be reset as the new baseline.

You can also reset a new baseline on a device. For information, see Reset the System Change service baseline for a device.

The System Change service requires the following configurations:

  • The service can only be monitored on discovered assets, not on devices that were manually created.
  • The service needs to have a recurring Windows Asset Discovery task targeted against the IP address of the target device.
  • A Windows probe collects the data presented in the service.
