This tool reads through your EE.log file and identifies the cause of death for anyone on your team. Your log file is located at %localappdata%\Warframe\EE.log in windows.
Your log file is not uploaded to the server. Everything is processed locally in your browser.
It can take up to 10 seconds for the log file to update with a new entry after a player dies if you're using this while the game is running, so if a recent death isn't showing up just wait a bit and try again.
The log file is erased every time the game is launched; you will lose the data from your previous session if you restart the game without making a backup copy of the old EE.log file.
Open EE.log by clicking the "Browse" button and pasting "%localappdata%\Warframe\EE.log" into the file dialog
