How to collect Chrome device logs

Chrome version 85 and later

Before contacting support, we recommend that you collect logs from your managed Chrome device and run them through the Log Analyzer to see if you can pinpoint the problem you’re experiencing. If you can’t resolve your issue, have these logs handy when you contact support. 

For more information about what these logs contain, see Remote log collection for ChromeOS devices

Collect general Chrome device logs

There are two ways to collect general device logs:

   2. (Optional) Enter your email address.
   3. (Optional) Enter the description of your issue.
   4. Click Continue.

6. Click Export.
7. Select the folder where you want to create the log file.

   2. Include all log files collected by debugd as a separate archive
7. (Optional) Under Options, select additional checkbox options, if needed.
8. Click Store System Logs.

Upload or export the logs from the Downloads folder to an external storage. You can then upload them to the NetLog Viewer or your support ticket.
