Is there a way to see how much ~memory~ storage remains on my Nucleus Plus Unit?
No. Itās an appliance, not a general purpose computer.
RAM or disk?

Now whereās the logic in this statement? Being conceived as a single-purpose computing appliance doesnāt make it less of a computer, and wouldnāt at all impede a Nucleus being able to report back RAM usage and hardware temperature. That its designers felt this wasnāt necessary is something else altogetherā¦
I would call my fridge an āapplianceā, but it reports back its temperature, gives alarm when it thinks its water filter should be changed, etc etcā¦
Your fridge probably doesnāt report the temperature and RAM usage of its motherboard, though; only attributes that are associated with its functions as an applianceā¦
Doesnāt make your statement any more logical or stringent, though. A Nucleus Plus still is a server computer, even if conceived as only to run Roon and nothing else. We have heard many times that it simply will crash if it runs out of RAM, instead of giving feedback about its RAM usage and by doing so giving the user a chance to upgrade RAM before a crash. Do āappliancesā simply crash instead of giving a warning in time?
That thereās no direct way of having a Nucleus appliance connected to a UPS and the UPS being monitored from the Nucleus and thereby allowing a graceful shutdown of the Nucleus in case of the UPS running out of battery power, is another oversight in my humble opinion. Itās still a server computer, and we have been told that a sudden hard shutdown could lead to database corruptionā¦
And lastly I think that hardware temperature feedback and warning (alarm) is a thing no passively-cooled computing āapplianceā should miss, especially when internal SSD are quite sensitive to overheating.
At least for end customers thereās currently no known way to access the minimized running Linux OS by e.g. Telnet or SSH. This is by purpose. You would also need some basic Linux command line tools in order to retrieve such system information. Such tools may or may not be already installed. We donāt know.
Bill, my answer to you would be that no, the Nucleus Plus doesnāt allow you to see the RAM memory usage, and this is so not because itās an appliance, but because its designers felt that it wanāt a necessary or desirable function to have.

Roon OS has an admin web page, which does give feedback about disk usage. It could very well include feedback about RAM and CPU usage, hardware temperature sensor readings, etc. That it doesnāt do so has been sold to Roonās customers as by design ābecause itās an applianceā. Itās my personal opinion that thereās no logic in this statement, that it being an āapplianceā doesnāt necessarily mean it couldnāt give useful feedback to its users. To me itās an oversight, an over-simplification of what in the end still is a server computer.
If the Roon OS designers felt it was desirable to have their users see feedback about RAM, CPU and hardware temperature, they would have provided the tools to being able to do so on the admin web page. But please donāt tell me that it doesnāt do so ābecause itās an applianceā. Nothing stops an appliance from giving useful feedback about its critical resources. If it doesnāt, to me itās an oversight by the applianceās designer.

The above is just about the only sensible reply in this thread.
Sheesh, while several go off on a tangent/tirade about computer appliances and RAM usage display (or lack thereof), Billās reference to Nucleus Plus āmemoryā remaining probably means disk storage available. Just look at his posting history.

Yes but the world could do with more people arguing with each other right now couldnāt it?
Now please excuse me whilst I pop over to the Audio Science Review thread

Disk, I think. I want to know how much storage remains on the server. If thereās no way to tell, and if the unit simply crashes after the memory is full, then that would seem to be a real problem. If thereās really no way to tell, then thatās shocking to me, absolutely shocking.
(I donāt know how RAM figures into all this. I assume itās analagous to human āworking memoryā for completing tasks in real time.)
Simply go to the web admin interface:
You will see how much is free on the main (database) storage and the internal music storage:

OK, thank you. Thatās extremely helpful.

Hi Bill,
Disk space is typically referred to as storage space.
Random Access Memory (RAM) is what the CPU uses to hold the programs it is running and some of the data it is operating with (that needs to be accessed and updated quickly).
Hope this helps.
PS if youāre interest hereās a couple of Wiki pages to study ā¦
