Zen monitor is monitoring software for AMD Zen-based CPUs.

zenmonitor's Issues

RAM usage slowly grows over time

Hello!

First of all I want to thank you for making such an amazing piece of software for us Ryzen users on Ubuntu! :D

Now, a small issue.

Today I noticed that I had too much RAM occupied in my system monitor. When I ordered the processes by memory usage, I saw that zenmonitor was using 3.2GB of RAM! (I don't have a screenshot because I closed it)

Closed it, opened it again and saw it start at ~10mb of RAM. Left it open and studied it a bit and saw the RAM usage go up by 200-300kb each couple of seconds. I had my session open for like 12 hours or more and that's how I got to 3.2GB RAM usage.

Fresh opened zenmonitor:

10 mins of uptime:

Enlarge the window on start so that all rows are visible.

Now it always starts like here with fixed size. GTK 3.28.

PS Should have in mind that the number of rows will be different if started with or without the access to MSR (sudo).
PPS Maybe add a Capabilities workaround note in README?
$ sudo setcap cap_sys_rawio,cap_dac_read_search+ep ./zenmonitor seems suffice.

PPA

It would be great to have a PPA for the people in the ubuntu-verse.

By the way. Great work on the module and gui.

improvements

Hi can u add the frequency for each core. It's available in /proc/cpuinfo so i don't think it will be hard to implement. It would be cool it you could do that.

No Temperature Readings with 1700X (but works in PSensor)

Using the zenpower driver I can get a temperature reading in PSensor but not in Zenmonitor. I'm running Kernel 5.0.21.

Additionally, running "sensors" in terminal gives the missing info:

No core x frequency

I have installed zen monitor and zen power but I don't see the core x frequency. Any suggestions would be appreciated along with any questions to help me further figure out why.

get_cpu_dev_ids is broken on 3900X

I have a 3900X and I noticed that zenmonitor was always reporting the same speed for core 3 and 4, which seemed to be a bug. I traced the code and it turns out it was reading cpu7 for both of them.

Looking closer I noticed that the cpu*/topology/core_id do not cover the range 0-12 as expected by get_cpu_dev_ids().

This is a patch to fix the problem, and it displays the coreid in the list rather than it's index.

I'm sorry it's just inline but for some insane reason github wont accept patches as attachments.

Zen Monitor has swapped Node labels for Tdie and Tctrl

Zen Monitor has swapped Node labels for Tdie and Tctrl.

Core temperature doesn't show

I have installed zenpower and zenmonitor, it shows Power and Frequency, but not temperature or fun speed:

I have Ubuntu 19.10, kernel 5.3
AMD Ryzen 3900x
Gigabyte x570 UD

Would you please respond to my issue #28

Hi, I would appreciate a courtesy response to my issue #28 which I raised 24 days ago and have not received any comment from you yet.

The labels for Tdie and Tctrl are swapped. Tctrl is always higher on cpus with an offset greater than 0°C

Zen Monitor is showing the opposite on Threadripper. The ZenPower driver labels are correct.

Zen3 (Ryzen 5000) support

After patching zenpower as described in ocerman/zenpower#39 I got zenmonitor working on a Ryzen 5000 series processor as well. Zen3 is familiy 19h. Everything else seems to be similar to the previous versions.

More stats may be helpful

Hi, thank you very much for offering the tool, it is really useful to monitor the CPU during heavy load.

I was wondering if it is possible to add more stats like 5-sec, 15-sec, 60-sec moving avg?

Detects only last 6 cores

Running on linux Mint kernel 5.5.6, threadripper 2970
All is well except for the fact that the frequency of all cores except for the last 6 is not detected (the cores are detected but the frequency displays 0)

Number alignment in columns

Hi,

really nice and easy to build software.

There is something that do bugs me a little:

Not aligned decimal separators and units between different rows in single row, are really meh, similar "Frequency" substring is not aligned for cores 10 - 15 (but it is less annoying that the value columns).

Zenpower and Zenmonitor data is flipped

Hi, Zenpower and Zenmonitor report the Tdie and Tctrl values flipped relative to each other on a threadripper 1950x, as per the picture zenpower says Tdie is 25c and zenmonitor reports 52c

An option to display index of core instead of core_id?

So, as I undersntand now it shows core_id, but maybe we need a flag to display the index, as in htop and lscpu?

Only showing CPU frequency (AMD Ryzen 7 4800H)

Hello,

I've installed both zenpower and zenmonitor AUR packages. Everything was fine, but the monitor only shows the core frequencies. I've enabled MSR driver.

I'm with Manjaro 20.0.2 (kernel 5.6.15-1). Please let me know what more information you'd need.

Only 1 node displayed for threadripper CPUs

When using Zenmonitor it only displays the temps, voltages and from only one threadripper node.

Discrepancy between GUI values and actual hwmon data

Hi,

I am a bit puzzled by the values I see in the gui for the CPU Core Voltage (SVI2). The gui shows values like 1.013 V but when I check manually I get a completely different value.

$ cat /sys/class/hwmon/hwmon2/name
zenpower

$ cat /sys/class/hwmon/hwmon2/{in1_label,in1_input}
SVI2_Core
1407

Same goes if I use the sensors command.

$ sensors | grep SVI2
SVI2_Core:     1.41 V  
SVI2_SoC:      1.07 V  
SVI2_P_Core:  17.61 W  
SVI2_P_SoC:   12.65 W  
SVI2_C_Core:  12.52 A  
SVI2_C_SoC:   11.77 A  

Shouldn't the reported values be the same?

Thanks

Core Voltage SVI2 same Sensor as HWInfo?

I know that might be a silly question. But i currently investigating some Issue i have on Linux and i suspect it has to do with different Voltages Linux uses.
I discovered that the Voltages on the "Core Voltage SVI2 TFN" Sensor on HWInfo seems to report a higher Votage than the Core Voltage SVI2 Sensor on Zenmonitor (Ryzen 5000). I now wonder do these tools use the same sensor?

What is the license of this project?

Wrong very high value in Max Package Power

I've seen it several times. This is exactly 0xA'0000'0000'0000
If the bug can't be found, maybe put a check for a value to be adequate and discard any value >5000 W, for example.

GUI wont load when run as root with EPYC 7642 48-core

I did the polkit install on Ubuntu 20.04.1 with several of my systems, but one wont launch. It works fine when not run as root, but when trying to run as root to get more sensor readings, it just hangs and no fields populate. Attempting to interact with the GUI i get the prompt that it's not responding and I have to force quit it.

I have two nearly identical systems. ASRock Rack EPYCD8 motherboards, with the same DDR4-3200MHz ram in both. one system running an EPYC 7402P 24-core and another running a 7642 48-core. the installs were done at the same time in the exact same way on both. installed the zenpower driver and blacklisted the k10temp driver on both, followed the ubuntu instructions exactly. everything works on the 24-core system, but the 48-core system just hangs when trying to load as root. the 48-core will load zenmonitor if not run as root.

let me know what I can do to help if you need more info.

cli mode

Hi,
will be possible to use it in cli mode (without gtk)?

Zen CPU Not Detected

I am trying to use zenpower. When I install it, and use sensors or psensor, I do not get any data about the CPU temperature. In my attempts to use zenmonitor, I get an error saying Zen CPU Not Detected.

This is the output of lscpu, indicating that the CPU is recongized by my system.

Build Fails on GCC 10

Trying to build this on an up-to-date Arch or Manjaro (or other Arch derivative) will fail, with the following errors:

This is with both the zenmonitor and zenmonitor-git AUR packages, as well as trying to build directly from this repo. The issue is GCC 10, after downgrading to 9.3, the build succeeds and the program works perfectly.
