Hi there,

I'd like to access the process object inside the function code, such as to know the memory usage of the runtime:

```auto
msg.payload = process.memoryUsage()

```

Is there a way to do this?

Thanks

Hi @namgk,

If you are running Node red 1.3 or greater you can enable in your `settings.js` file the option to load additional modules (as is the node.js `process` module).

More info on this new `functionExternalModules` Node-red feature [here](https://nodered.org/docs/user-guide/writing-functions#using-the-functionexternalmodules-option)

Once you have that setup .. all you have to do is require the module and use it in the function with the command you have in your post.
