n8n timezone? logs retention?

[potemkin_ai]

Hello! n8n reads from Docker environment 3 key values:

1. timezone
2. key to encrypt all of the credentials
3. retention logs policy

From what I can see, since my credentials survive n8n instance restart, item number 2 seems to be good, but since my cron node seems to be executing at the wrong time, the time zone is not - could you please, check / fix that?

And one more thing - what is the logs retention policy? How many hours of logs are kept?

Thank you! And special thanks for adding n8n to the apps!

@potemkin_ai looks like you can set GENERIC_TIMEZONE as suggested by https://docs.n8n.io/getting-started/installation/docker-quickstart.html#setting-timezone . On Cloudron, you can edit /app/data/env using the file manager and restart the app.

I put a note in https://docs.cloudron.io/apps/n8n/#timezone

As for the logs, we keep last 10MB of logs per app.

[potemkin_ai]

@girish thank you!

Is there a way for Cloudron to pick up for that purpose a Time Zone that I'm configuring at the settings page?

@potemkin_ai Currently, no, but I think that's a good idea worth investigating!

@girish thanks, yes, that would be very nice, if n8n container's time zone (and probably other services) would be regulated that way.

As for the logs - I realized that we might speak about different kind of logs here - n8n stores execution logs, that might fill up the disk very quickly: https://community.n8n.io/t/hard-disk-full-where-to-delete-logs/2298

Here are the environment variables that seems like of the most importance at n8n:

GENERIC_TIMEZONE=
WEBHOOK_TUNNEL_URL=https://FQDN/ #this one, to make sure webhook URL will work fine
N8N_ENCRYPTION_KEY=.. #to avoid loosing credentials on docker restart

#clear execution logs
EXECUTIONS_DATA_PRUNE=true
EXECUTIONS_DATA_MAX_AGE=672

@potemkin_ai ah, i see. Do you think the defaults you have provided are reasonable? If so, I can put them as part of the default install.

[potemkin_ai]

@girish absolutely!

It makes n8n to perform in right timezone, have proper webhook URL, keep credentials (not loosing then during the docker rebuild), avoid disk overflow from the executions log.

[girish]

OK, I have put this as the default for new installations.

[potemkin_ai]

@girish lovely, thank you!

@potemkin_ai I’m struggling to get the time zone set up. Do you have any suggestions as to what I did wrong? These are my env settings:

Set the logging level to 'debug'
export EXECUTIONS_DATA_SAVE_MANUAL_EXECUTIONS=true
export EXECUTIONS_DATA_SAVE_ON_ERROR=all
export EXECUTIONS_DATA_SAVE_ON_SUCCESS=all
export N8N_LOG_LEVEL=info

GENERIC_TIMEZONE='Europe/Berlin'
TZ='Europe/Berlin'
WEBHOOK_TUNNEL_URL=https://top.level.domain/
N8N_ENCRYPTION_KEY='redacted'


EXECUTIONS_DATA_PRUNE=true
EXECUTIONS_DATA_MAX_AGE=672

[girish]

@andreasdueren you have to add export in front of each line

[andreasdueren]

@girish duh that’s probably why
