Log Pane

An overview of the Log pane in Motive, including troubleshooting steps for common error messages.

Overview

The status Log pane displays important events or statuses of the camera system operation. Events that are actively occurring are shown under the Current section, with all of the logged events saved in the History section for the record.

Open the status Log pane from the View menu or by clicking the icon on the main toolbar.

Status messages indicating a disconnected camera.

In general, when there are no errors in the system operation, the Current section of the log will remain free of warning, error, or critical messages. Occasionally during system operations, the error/warning messages (e.g., Dropped Frame, Discontinuous Frame ID) may pop-up momentarily and disappear afterward. This could occur when Motive is changing its configuration, for example, when switching between Live and Edit modes or when re-configuring the synchronization settings. This is a common behavior and does not necessarily indicate system errors as long as the messages do not persist in the Current section. If the error message persists under the Current section or there is an excessive number of events, there may be an issue with the system operation.

Export Log

To export the log history to a text file, click the button at the top left of the log pane. Open the file in Notepad or the text editor of your choice. The file can also be opened in Excel.

Status Messages

Status messages are categorized into five categories: Informational, Warning, Error, Critical, and Debugging. Logged status messages in the history list display in chronological order by default. The log history can be sorted by any field by clicking the column header. The sorted column is indicated with a cyan header.

{ Device } Disconnected

Camera System: A mocap camera or other OptiTrack device (e.g., an eSync) was disconnected from the system.

Troubleshooting steps:

• Try replacing the cable or device if possible;

• Connect to another port on switch or PC;

• Try connecting the device (e.g., an eSync) directly to the aggregator switch and auxiliary power;

• Make sure the correct power adapter is being used.

---

Dropped Frame

Camera System: A mocap camera dropped a frame of data, either because of incomplete packet delivery, buffer overflow, or it was not able to provide the frame in the time required to be part of the current frame group.

Troubleshooting steps:

• General networking troubleshooting;

• Check if PC specs are sufficient for system;

• Check if Windows background processes are causing any interruption;

• Monitor system performance using the Windows Task Manager;

• Validate if the dropped frame was in 2D or 3D. Data can be reconstructed in Edit mode unless 2D data is missing.

Troubleshooting steps: General networking troubleshooting.

---

Synchronizer Queue Overflow

Camera System: The camera frame group synchronizer's queue is full and is unable to add a new frame group to the queue, so it is delivering a partial frame group instead.

Troubleshooting steps: General networking troubleshooting.

---

Missing synchronization telemetry
