MMM-SystemMonitor

[btastic]

Hello,

I wanted something to display my current system stats to monitor my magic mirror hardware.

There is a module called MMM-SystemStats, but it seemed buggy and was seemingly not maintained anymore. So I decided to make my own.

https://github.com/btastic/MMM-SystemMonitor

Feel free to discuss, ask questions or add suggestions for further development.

Best regards
Ben

@btastic Nice. If I hadn’t already done some stupid pi tricks to get that info into a notification so I can display it with MMM-Valuesbynotification…

[lxne]

@btastic MMM-Tools does that, too.

[btastic]

@lxne Ah bummer I didn’t know about it. Thats mostly what I had envisioned.

[MMRIZE]

MMM-Tools is archived. (with some complex history)
I rarely support that module. It became too far during on my absence from what it was, and I made at the first time. Anyway, I have left it as it currently is.
If you want to be a successor, always welcome.

[BKeyport]

@btastic to double down on what @MMRIZE said - taking over someone else’s archived module is an exceptional way to learn how to do things. I Would highly encourage it, as the author has directly said he’s okay with it. I did that with a module myself. Taught me so much about javascript working out bugs in an existing module and adding my own flair (and I really should get back on it for one bit…)

[btastic]

@BKeyport I will probably take a thing or two, but I think the code can be written a bit better by todays standards. The project is almost 6 years old and was probably refactored a few times. No offense towards @MMRIZE - thats probably one reason he does not want to develop it further without rewriting it.

[MMRIZE]

@btastic You are right. Cheer up for your work!
I wish a new module which can be more flexible and modular with modern techniques, and especially, not dedicated to RPI(recently I never work with it), but I have not enough time and interest to do so…

[btastic]

@MMRIZE Thank you.

I want to make it OS independant too, but that will be a bit harder I think. I don’t have that much time either. But will work on it in the foreseeable future.

Installed, added to config.js

		{
            module: 'MMM-SystemMonitor',
            position: 'bottom_right',
            config: {
                updateInterval: 60000,
                cpuThermalZone: 0,
                units: config.units,
            }
        },

MM fails to load.
Comment those lines out, MM is OK. What have I missed?

@Richard238 what is the end of the last prior module

[Richard238]

@sdetweil

It’s the currently misbehaving weather forecast:

		{
			module: 'weather',
			position: 'top_right',
			header: 'Weather Forecast for: ',
			config: {
				type: 'forecast',
				location: 'nnnnnnnnn',
				locationID: '11111111',  //ID from https://www.openweathermap.org
				apiKey: 'aaaa444444444444444444'
			}
		},

		//{
            //module: 'MMM-SystemMonitor',
            //position: 'bottom_right',
            //config: {
                //updateInterval: 60000,

@Richard238 what is the error?

npm run config:check

@sdetweil said in MMM-SystemMonitor:

[2025-02-02 21:35:32.330] [INFO]  Checking modules structure configuration ... 
[2025-02-02 21:35:32.511] [ERROR] Cannot read properties of undefined (reading 'units') 

Module says:

units: config.units,

And also tried with

units: metric,

Which failed with:

[ERROR] metric is not defined 

config.js towards the beginning says:

units: 'metric',

[sdetweil]

@Richard238 to the right of :

Numbers and true/false do not need quotes
Any thing that has a letter needs quotes

[Richard238]

@sdetweil

I don’t understand, sorry?

[sdetweil]

@Richard238 in config.js all properties are

name : value

The value, to the right of the colon (:)
If a number or tr/false
Does not need quotes

If it contains a letter or symbol
It needs quotes

units : metric
To the right is metric
It has letters, so needs quotes

[Richard238]

@sdetweil

That’s fixed it.

Module in config.js

units: 'config.units'

config.js before modules

was

units: 'metric',

Changed it to

units: "metric",

Quite how Free Memory can be 128% I’ve no idea, that’s for another day.
For now, it’s working. Thank you!
