Log before crash

Configuration
1

Hi,

My home assistant is installed on a Odroid N2+ (Home assistant OS).

I would like to have a copy of the log file each times home assistant restarts. This way, when HA crashes I still have the last log.

How can I do that ? Running last version of HA.

If You have Terminal Installed The “rotated” logs are to be found in “/var/log/journal”
Thou not in “clear-txt”
If HA Crashes ( so the txt-log-file is “renewed/corrupt/gone” )( Sometimes, it’s not like there is anything to “copy” ( I.e the milli-seconds before it crashes )

HA previously had a txt-logfile in /config , But Now this works Different !

Goto. /Setting/system/logs , Click to the Right on the 3 Dots (RAW-Log), … scroll until you get tired :wink: … Or copy/download it to your PC/Laptop
It’s reading from the Journal-Files !

Thanks for that !

@Tsar you can restore the old logfile functionality by following this if you’re not concerned about space.
Easier to read & to distinguish which logs belong to the previous session before the restart.

Is this a one time step or has to be done after every HA update again?

Yep, one time deal. No need to reapply it after updates.

Ah. Ok. Thought about because of the rebuild step.

BTW. Here it is already restarting in this step two automatically

ha core options --duplicate-log-file=true
ha core rebuild
ha core restart

Tbh I didn’t check if it restarted by itself on step 2. I guess an extra restart won’t hurt. At the very least you’ll see the old log (log.1) working
