Capture logs for Google Hangouts

Issues with Google Hangouts are logged on your local machine. If you contact Google Support for help, they might ask you to do the following:

  • Send your Hangouts logs
  • Submit feedback from within Hangouts when the issue occurs
Capture Hangouts plug-in logs (non-Chrome browsers)

Complete the following procedure to capture logs from the Google Hangouts plugin installed in browsers other than Chrome.

Tip: See Capture WebRTC logs in Chrome to capture logs in a Chrome browser or on a Chromebook. 

  1. On the affected computer, run the following commands to enable verbose logging:

    Windows command prompt:

    • reg add "HKCU\Software\Google\Google Talk Plugin" /v loglevel /t REG_SZ /d LS_VERBOSE /f
    • reg add "HKCU\Software\Google\Google Talk Plugin" /v logfile /t REG_SZ /d %USERPROFILE%\Desktop\gtp.log /f
    • reg add "HKCU\Software\Google\Google Talk Plugin" /v plugin_log_level /t REG_SZ /d LS_VERBOSE /f
    • reg add "HKCU\Software\Google\Google Talk Plugin" /v plugin_log_path /t REG_SZ /d %USERPROFILE%\Desktop\gtpbp.log /f

    Mac/Linux terminal:

    • defaults write loglevel -string LS_VERBOSE
    • defaults write logfile -string $(cd && pwd)/Desktop/gtp.log
    • defaults write plugin_log_level -string LS_VERBOSE
    • defaults write plugin_log_path -string $(cd && pwd)/Desktop/gtpbp.log
  2. Restart the computer to make the verbose logging changes take effect.

  3. Attempt to hold a Google Hangout on the computer with logging enabled. Proceed to the next step only after you reproduce the problem you're reporting.

  4. Find gtp.log and gtpbp.log in the desktop and the compressed log files (gtalkplugin-c*.log.bz2) in the following folders, and attach them to an email to your support representative.

    • On Windows:
      %LOCALAPPDATA%\Google\Google Talk Plugin

      IE with virtualized file system:
      %LOCALAPPDATA%\Microsoft\Windows\Temporary Internet Files\Virtualized\C\Users\%USERNAME%\AppData\Local\Google\Google Talk Plugin

      Windows XP:
      C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\Google\Google Talk Plugin

    • On Mac OS X:
      ~/Library/Application Support/Google/Google Talk Plugin

    • On Linux:

    The log folder may contain multiple old log files that were generated previously. Unless instructed, please send only the latest log files that correspond to the reported problem.
  5. To revert back to the default logging setting, run the following commands:

    Windows command prompt:

    • reg delete "HKCU\Software\Google\Google Talk Plugin" /v loglevel /f
    • reg delete "HKCU\Software\Google\Google Talk Plugin" /v logfile /f
    • reg delete "HKCU\Software\Google\Google Talk Plugin" /v plugin_log_level /f
    • reg delete "HKCU\Software\Google\Google Talk Plugin" /v plugin_log_path /f

    Mac/Linux terminal:

    • defaults delete loglevel
    • defaults delete logfile
    • defaults delete plugin_log_level
    • defaults delete plugin_log_path
Capture WebRTC logs in Chrome or ChromeOS

Complete the following procedure to capture WebRTC logs in a Chrome browser or on a Chromebook:

  1. If you are using a ChromeOS device: after the device restarts, login and reproduce the Hangouts issue.
    If you are using just the Chrome browser: restart the browser and reproduce the Hangouts issue.
  2. To retrieve the Chrome native logs, open a Chrome browser tab and enter chrome://webrtc-logs.
  3. Note the date, time and Report ID.
  4. To retrieve the WebRTC JS logs, open a new Chrome browser tab and enter:
    filesystem: .
    Tip: Be sure to copy the entire URL including "filesystem:" and paste it to the browser address bar.
    These log files are only preserved for 5 days. All logs older than 5 days will be automatically purged.
  5. Send the information and logs to Google support.
To avoid manually collecting logs in the future, please enable the option to automatically send them to Google. To do this, start a Hangout, click the Settings gear, and check the box next to Report additional diagnostics to help improve Hangouts.
