Hi! I'm sure soeone esle has already asked about this in past, but googling it I can't find a proper answer, also searching here in the forum. THis night my Raspberry for the first time had a problem, the IP protocol stopped somehow, I guess it's a kernel problem, this morning the ping worked but I…

The log file location depends on how you run Node-RED. For example if you run Node-RED using pm2 it will be different that if you run straight from the command line. If you are using the pi install you can run the command as listed on the raspberry pi page in the docs. You can change the amount o…

I used sudo systemctl enable nodered.service as in the main instructions, I installed node red without root, where are log files? what names they have? only console.log? I suppose that here is how to manage the logging level: https://nodered.org/docs/user-guide/logging how many days will it be pr…

If you are using a raspberry pi the answers to some of the questions are on the Raspberry Pi page in the documentation. How many days are preserved of the logs on a raspberry pi? That's a question you can google.

In this guide I can't find the path: https://nodered.org/docs/user-guide/logging Somebody please know it? Thank you

Hi @Barabba11 if you have followed the Raspberry Pi install docs here: https://nodered.org/docs/hardware/raspberrypi then, as described on that page, then you should also have the node-red-log command. But if you haven't used our install script, you won't have that command. In which case, you shou…

both of them working, thank you, but I can see only data only from the last time it started. Any chances to see the contant of the file with old logs? I need to know what happeed this night. Maybe as default Node red doesn't log to file, and add history at avery restart (instead of delete all previ…

When running as a service, the log is entirely managed by journald outside of node-red. I haven't looked at what configuration options it provides, but I assume it must provide options to extend the history it keeps. A quick google on the topic finds this: https://www.loggly.com/ultimate-guide/linux…

If you look in /var/log/syslog you will see it is there also, but mixed up with all the other syslog stuff.

Colin thanks, yes there I can see all, mixed up. For me it's ok since I can see what happened in the night. It's not Node red (but it was working instead), it was the kernel, the IP TCP was not more working and also logging was stopped, so I don't have many elements..

[image] knolleary: sudo journalctl -f -u nodered -o ca I add this to my package.json file scripts section so that I can run the command npm run log. That way I don't have to remember the ugly, complex command.
