Sometimes, in order to resolve an issue, Player Support may ask for log files from your League of Legends client. These logs help us understand what’s happening behind the scenes when you launch the game, navigate the client, or enter a match.
League of Legends uses a unique client system, which means it generates additional logs that are not found in other Riot games. This guide covers those League-specific logs and where to find them.
Please note that we usually only need one or two files to investigate your issue, so there’s no need to gather everything listed in this article :)
Looking for general logs for League or other Riot games? Check out our general logs guide.
r3d Logs
A match log is created each time you play a game. It contains vital information about your loading process and will log any errors that occur during the course of the game. These logs are essential for troubleshooting in situations where you have problems in-game.
Each file appears like this:
[yyyy-mm-ddT15-40-03]_r3dlog.txt, where yyyy-mm-dd is the date of the match played.
You can find them here:
C:\Riot Games\League of Legends\Logs\GameLogsUnder the time and date stamped folder for the game in which you had issues.
NetLogs
A network log is created each time you play a game. It contains vital information about your connection over the course of the game. These logs are essential for troubleshooting in situations where you have problems in-game - usually with lag, rubber-banding, or disconnections.
Each file appears like this:
[yyyy-mm-ddTHH-MM-SS]_netlog.txt, where yyyy-mm-dd is the date of the match played.
You can find them here:
C:\Riot Games\League of Legends\Logs\GameLogsUnder the time and date stamped folder for the game in which you had issues.
League CLient Logs
These logs record various aspects of the platform client. Basically anything from launching the platform client all the way up until the end of champion select gets logged into these files.
Each client session generates 5 logs:
| LeagueClientLauncher | Logs events when the client is launched and verifies configuration |
| LeagueClient | Contains most backend information from launch to closing the client |
| LeagueClientUx-gpu-process | Checks the graphics processor for the UX |
| LeagueClientUx | Records front-end interactions (what you see and interact with) |
| LeagueClientUx-renderer | Tracks what pages are rendered in the client |
These logs contain all the information about errors from the Login Screen through champion selection. Logging ends when you enter a game after the champion select timer expires.
Each file will appear like this:
2017-04-21T12-00-40_17864_LeagueClient
(The file name includes the time it was created.)
You can find them here:
C:\Riot Games\League of Legends\Logs\LeagueClient LogsAdditionally, you can use the Riot Repair Tool to gather logs into a folder on your desktop.
