Usage Stats Not Displaying Correctly on ARM64 #788

EliasRipley · 2022-12-04T09:38:42Z

Bug Report

System Information

Ubuntu 22.04.1 (Oracle VM)
2.4.0.10
Release (aarch64)

I confirm:

that I have searched for an existing bug report for this issue.
that I am using the latest available version of AMP.
that my operating system is up-to-date.

Symptoms

What are you trying to do?
See the CPU usage and RAM usage of a Forge MC Server.
What are you expecting to happen?
To be able to see the circular % graphic give detail.
What is actually happening? ('Nothing' is not an acceptable answer!)
The circles stay at 0% even when server is operating.

Reproduction

Open up the ports on the VM Cloud instance. Follow the AMP instructions to install.
Create a Forge Server.
Start it.

This also affects Paper servers (probably all). I believe it is specific to Ubuntu 22.04 on ARM, based on:

my Ubuntu 22.04 install on AMD working fine
my install on ARM previously working fine on 20.04 (ie before upgrade to 22.04)

Perhaps there is something different with how htop behaves on 22.04 on ARM.

PhonicUK · 2022-12-05T12:44:45Z

Does htop report the expected usage?

EliasRipley · 2022-12-05T12:59:43Z

Yeah, htop command seems to be working fine.
Managed to find a nice SSH app on my phone to be able to check while out and about.

PhonicUK · 2022-12-12T12:45:04Z

Can anyone verify if this is in fact an issue specific to Oracle VMs? Or does it occur on other ARM64 systems? Ideally on bare metal.

IceOfWraith · 2022-12-27T10:01:20Z

This happens on my rpi400 as well.

IceOfWraith · 2023-01-03T13:29:30Z

Note that the overall stats for the server shows the correct RAM amount available, but no CPU core count. This is from an Oracle instance, but same for a Pi.

ivybowman · 2023-01-26T21:31:01Z

Gonna look into this on my oracle vm, specifically if using a different os works

PhonicUK · 2023-01-31T13:40:14Z

What's the output of lscpu on these systems? If AMP is reporting 0C/0T then that would cause metrics calculation to get funky.

This is the output of the command on an oracle vm on 22.04.

Ah interesting! So it reports as 0 sockets, and uses 'Clusters' rather than 'Cores'.

AMP was taking the 'Threads per core' value and multiplying it by the 'Cores per socket' which made everything have a value of 0.

Fixed in CI.

I am still experiencing issues with the latest version. Is it supposed to be fixed now? The cpu and ram info reports correctly although usage is broken.

Snablorangen · 2023-02-28T23:34:05Z

I'm still experiencing this as well. Running Ubuntu 22.04.2 on Oracle VM 2.4.2.0

Greelan · 2023-04-01T05:06:19Z

So, more data points to allow this to be fixed properly.

No material differences noted.

Same difference in language/presentation as noted earlier in this thread. Seems like the earlier changes in AMP haven't properly catered for this.

`/proc/cpuinfo`

ARM on left, X64 on right:

So, much less data on ARM.

However, I understand AMP uses lscpu in preference, and Oracle instances have that installed by default.

Bumping this one. I am running AMP on a RPI 4 and it is not showing any details for me as well. Numbers are zero

I will bump this one, too. Specifically Oracle Ampere VM. The cpu core numbers are fixed, and RAM amount is also correct, but usage stats do not work. Always 0% CPU and 0MB RAM stats in the instance although it is running:

htop works fine. Output of lscpu is following:

Vodianoi · 2024-05-04T08:42:02Z

Same here with rpi5 (Raspberry PI OS (Debian 12)) : lscpu and htop work well but no CPU/RAM/TPS working on AMP web interface.
Is there a way to "fix" this temporarily ?

darkkon21218 · 2024-05-30T00:42:49Z

Bumping this as well. My memory usage and totals are correct but my CPU usage has always been at 0% for any of my instances.

PhonicUK · 2024-05-31T14:57:10Z

This is a 'wontfix' for the time being because the cause of the problem cannot be identified at this time.
