I am looking at the file context write sequence to try to see if I can see any improvements to reduce the likelihood of corruption triggered by power fail. How can I enable the trace logging in [node-red/packages/node\_modules/@node-red/runtime/lib/storage/localfilesystem/util.js at master · node-red/node-red · GitHub](https://github.com/node-red/node-red/blob/master/packages/node_modules/%40node-red/runtime/lib/storage/localfilesystem/util.js)? I tried setting the log level to trace in settings.js and lots of extra stuff came out, but not the util.js logs.

I don't know the answer. But have you tried using the inspector nodes? That lets you track what is happening in your browser dev tools.

Thanks. I don't really need that complexity. I just want to understand what it is doing. The existing optional logging would do, at least initially, if I could just switch it on.

The code uses  
`const log = require("@node-red/util").log;`  
Then logs using `log.trace()`, but setting log level to trace in settings.js does not enable it.

The normal approach for custom nodes is to use `RED.log.trace()` of course. Hard to track whether the direct require of the util log is the same thing. I assumed it was.

Personally, I find that, unless you set up a custom logger, the amount of data from a working system when logs are turned up to trace level is unusable.

Instead, I put a breakpoint in the area of code I'm interested in and then can step through and see the data passing through as well.
