Network, System and League of Legends Logs

What is a Process List?

A process list shows all the software that is currently running on your PC. Some software might conflict with League of Legends and we can identify the common issues by looking over this list.

Obtaining a Process List on Windows 10 and later versions:

• Press the [Windows Key] (that is the key on the left side of the space bar, between ctrl and alt) + R
• Type cmd in the search bar and click "Ok". You should now see a black window with white letters.
• Highlight and copy the following text: tasklist /v >"%USERPROFILE%\desktop\Process.txt"
• Paste this into the cmd window (black box with white letters) by right clicking and selecting "Paste". Do not use the Ctrl+V shortcut as it will not work!
• Press Enter.
• Wait 10 seconds while a text file with the Process List is created.
• You should find a Process.txt file on your desktop.
• Attach Process.txt to forum post or a support ticket. NOTE: Please do not paste the plain text into the ticket :)

What is a NetworkInfo?

This log provides us with information about your network adapter and your internal network configuration. It also shows us some basic information about your connection to the outside world.

Obtaining NetworkInfo information

• Press the [Windows Key] (that is the key on the left side of the space bar, between ctrl and alt) + R
• Type cmd in the search bar and click "Ok". You should now see a black window with white letters.
• Highlight and copy (right-click and select "Copy" or Ctrl+C) the following text (all of it, including quotes and parenthesis):

(ipconfig /all & ping www.google.com & netsh firewall show config & netsh interface ipv4 show subinterfaces & netsh interface ipv4 show ipstats) > "%USERPROFILE%\desktop\NetworkInfo.txt"

• Paste this into the cmd window (black box with white letters) by right clicking and selecting "Paste". Do not use the Ctrl+V shortcut as it will not work!
• Press Enter.
• Wait untill the command finishes running. When it is done, the cmd window will create a new line with a blinking cursor after the path. Alternatively, to be absolutely sure that it finishes, please wait 60 seconds.
• You should find a NetworkInfo.txt file on your desktop.
• Please check that the command ran properly - if NetworkInfo.txt contains a single line, it did not run properly.
• Please attach NetworkInfo.txt to a support ticket. Please be careful about posting this log on the forums as it reveals your IP address to the public.

What is DirectX Diagnostic?

This log gives us information about your system's hardware configuration.

Here is what you need to do to obtain a DxDiag (also known as DirectXDiagnostic):

• Type dxdiag in the search bar and hit 'Ok'
• The DirectX Diagnostic Tool will open. Press the "Save All Information..." button.
• Choose where to save the file (for example, your desktop).
• Attach the DxDiag to your response on the forums or support ticket.

What are Riot Client Logs?

Riot Client logs keep track of what's happening whenever you load the Riot Client, and can be useful in diagnosing a variety of errors.

Each file appears like this: [yyyy-mm-ddT15-40-03] _Riot Client.log, where yyyy-mm-dd is the date the Riot Client was used.

You can find them here:

5. From there, click Send to.
6. You’ll then select Compressed (zipped) folder.
7. Attach this newly zipped folder to your support ticket

What are the 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. Once you locate the logs, please attach them to your ticket.

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\GameLogs, under the time and date stamped folder for the game in which you had issues. 

What are the game.cfg and input.ini files?

Those files tell us about the options you have configured in League of Legends. Once you locate these files, please attach them to your ticket.

You can find them both here:

C:\Riot Games\League of Legends\Config

What are 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. Once you locate the logs, please attach them to your ticket.

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\GameLogs, under the time and date stamped folder for the game in which you had issues. 

What are LeagueClient Logs?

These logs record various aspect 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. Note that each instance on the client generates 5 logs associated with it:

• LeagueClientLauncher: This logs the events that occur when the client is launched. It verifies the configuration files are good to go and then launches the client with the settings in there.
• LeagueClient: This is the biggest of the logs because it contains pretty much all of the information that goes on with the client's back-end. Once the client successfully launches, it logs everything from the successful launch to closing the client.
• LeagueClientUx-gpu-process: This sub-log does a quick check on the graphics processor within your system for the UX.
• LeagueClientUx: This is the second largest of the logs. It records everything with the front-end experience; so things that you can see and interact with are found in this log.
• LeagueClientUx-renderer: This is another sub-log which tracks what pages need to be rendered onto the landing page of the client.

Its logs contain all the information about errors you receive from the Login Screen through champion selection. This logging function ends when you enter a game after the champion select timer expires.

Five logs are created per each client session, and each file will appear like this: 2017-04-21T12-00-40_17864_LeagueClient (The file name will include the time it was created - in this case: April 21st, 2017 at 12:00:40 (12PM)). Once you locate the logs, please attach them to your ticket.

You can find them here:

C:\Riot Games\League of Legends\Logs\LeagueClient Logs

Additionally, you can use the Riot Repair Tool to gather logs into a folder on your desktop.

What are Vanguard Logs?

Vanguard helps ensure the freedom from unsavory activity in-game, but sometimes it can cause unforeseen complications.

To see if that's happening to you, you can get Vanguard logs by following these steps:

• Press the Windows Key.
• Search for (or copy-paste) C:\Program Files\Riot Vanguard in your Windows Search Bar.
• There, you'll see a folder called Logs.
• Copy and paste the Logs folder to your Desktop, and right click the copied folder.
• From there, click Send to.
• You'll then select Compressed (zipped) folder.
• Now just attach this newly zipped folder to your support ticket!

Additionally, the logs the Riot Repair Tool gathers also contain your Vanguard logs.

Path Correction

Occasionally, we may have our Players use Command Prompt commands to retrieve information for us to help them troubleshoot their issue and get back to the fields of justice. We are careful to issue these requests where appropriate, however, it should be noted that some systems cannot correctly execute a command because the path to the command is not properly set.

For example, if the path to the ipconfig command is incorrectly set, you may receive an error similar to the following image:

(Note that this command should actually be pulled from C:\Windows\System32\ipconfig.exe )

If you are faced with this issue, please set the correct path for your Command Prompt by doing the following:

• Log in with Administrator privileges
• Click on the Start button
• Right-click My Computer and select Properties
• Go to Advanced system settings
• Click Advanced tab
• Click Environment Variables button.
• In the System variables box, scroll down to Path and highlight it
• Click the Edit button
• In the Variable value box, add to the very beginning of the text C:\WINDOWS\system32;
• Click OK three times.

Note: Make sure you include the semicolon.

After this, you should now be able to properly execute the ipconfig command. If you are having trouble with the instructions above and need to complete a command prompt to reply to us here in Player Support, please do not hesitate to ask the Support Specialist you are working with for further assistance.
