How to enable “Preserve Log” in Network tab in Chrome developer tools by default?

Question

How to enable "Preserve Log" in Network tools in Chrome developer tools by default? Everytime I press F12 and then select Network tab, I need to click preserve log checkbox to make it preserve request/responses. Is it possible to have it checked all the time by default?

By the way this feature works in "Firefox Developer" edition. When I click "Persist Logs" and close and then open the browser & DEV tools window again, it is still checked.

UPDATE - 6th March 2019

This will be fixed in Chrome 73. But if you want to try it before that then install Chrome Canary. It's working there. To enable/disable this persistence just go to Dev tools settings and check/uncheck Preserve Log under network section as shown below.

Thanks to the team for fixing it. Better late than never.

Answer 1

I have a small solution to that problem. I don't know whether it works correctly.First, click three dots->More tools -> Developer Tools. In that, click the three dots button(the name will be Customize and Control Dev Tools. In that, click settings.You will see a list of options with a main heading Preferences. From that, browse down to Console option. In that, just tick the option 'Preserve log upon navigation'. I guess this will solve your problem.

Automate keystrokes to set chrome with persistent logs on Network tab. Tested with Chrome 66.

• Make sure xdotool is installed
• Launch chrome
• Put the code below in a bash script chrome_auto.sh to send all the keys to: open a tab, dev tools, settings, set 'persistent logs', type the URL and hit enter.

#!/bin/bash

url="https://www.stackoverflow.com"
if [ -n "$1" ]; then
    url="$1"
fi

# find chrome window id
wid=$(xdotool search --class Chromium | tail -n1)
# build tab key sequence to set 'persistent logs'
tabkeys=$(for i in {1..24}; do t+="Tab ";done ;echo "$t space")
# base xdotool command
cmd="xdotool windowactivate --sync $wid"
# make chrome dance :-p
$cmd key ctrl+t
$cmd key F12
sleep 1
# open settings, move to desired option and select it
$cmd key F1 $tabkeys
sleep 1
# move cursor to URL box and type URL
$cmd key F6 type "$url"
$cmd key Return

Use the script as

./chrome_auto.sh "https://stackoverflow.com/questions/45133659"

• Also, chrome can be launched with dev tools open for every tab. If this is used, comment out the line with key F12

chromium --auto-open-devtools-for-tabs > /dev/null 2>&1 &
