Node-RED logs to the console where you ran the `node-red` command.

In windows, I do several types of logs: for the nodes, the console, nssm service ... To make a record of the console what I do is use the FS library in the "logging" section of the settings.js file

you could try to create a custom logger

If you give us more information on exactly what you are looking for then it may help. That is assuming that the information provided by @knolleary did not help.

On windows, by default you only get output from the node-red command. To actually "log" it into a file, you can do something like `node-red > log.txt`

Node-RED only produces one log... The one I pointed you at.

You can change the level of detail in the log using the logging property in your settings file.

Is there any way to view/import/capture the logs via the Node Red web UI ?

One bodge sort of way is to start Node-RED with it sending its ouput to a file  
e.g  
`node-red > /home/.pi/nrlog.txt`

and then using a file tail node to send it the the debug sidebar (but it obviously misses stuff until NR itself is up and running)

If you are running on a linux system using the systemd service file to run node-red then the output is sent to /var/log/syslog so you could use a tail node on syslog and filter out non-node-red lines.

In my case that Node Red running on Windows10, i found debug logs at **C:\Users\User\_name\AppData\Roaming\npm-cache\_logs**

 ![Node_Red_log](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/8/d/8d239e752a08e6956047dd66c6b55225112b267f.png)

PS.  
I selected the lastest log file and compared all activities beween the last update (02/09/2021) and the previous one (05/18/2020) in order to solve the problems unable to start Node Red by command as follows.

npm uninstall node-red-contrib-gpio
