What is a DSLOG file?
A DSLOG file is a binary data log file created by the FRC Driver Station used in the FIRST Robotics Competition (FRC), a program where high school teams compete with robots in themed engineering challenges. It stores information about a robot's operation during matches and practice sessions, such as robot mode (enabled or disabled), battery voltage, packet loss, CPU usage, and communication status between the driver station and the robot. DSLOG files help teams review how the robot and control system performed over time.
More Information
DSLOG files are one of two log files created by the FRC Driver Station each time it connects to a robot, with the other file being a .DSEVENTS file. The data is recorded as a timeline in DSLOG files, allowing users to analyze performance and identify issues that occurred during a run. You can typically find DSLOG files in the following directory:
C:\Users\Public\Documents\FRC\Log Files
NOTE: Unlike data log formats such as .WPILOG and .HOOT, which record data generated on the robot itself, DSLOG files store information from the Driver Station. This includes details about the connection between the computer and the robot, as well as system performance and communication status during operation.
How to open a DSLOG file
You can open DSLOG files with the built-in log viewer included with the FRC Driver Station (packaged with FRC Game Tools). Some third-party tools, such as AdvantageScope, can also read and visualize DSLOG data.
