Disk Usage Of Parent Disk And Disk Model For NVMe SSDs Are Not Shown

[govarthenan]

Disk tab automatically selects the home partition, which results, at least with my SSD, in no metrics displayed. Metrics are displayed correctly upon selecting the DDS device e.g nvme0n1 instead of nvme0n1p6, which was selected by default. - Screenshot and debug message:

You have a machine with new hardware. I will make some changes on the code for fixing the problems.
Can you write output of these commands?

Open '/sys/class/block/nvme0n1p/device' directory from file browser and open terminal here. Type these commands:
ls
cd ..
ls
cd ..
ls
cd ..
ls

I am looking for model file for reading the disk device model. This file is in device folder in the parent disk folder.

[govarthenan]

As far as i know, the device's name is nvme0n1, not nvme0n1p, and there is no folder with the path of /sys/class/block/nvme0n1p. Folder like /sys/class/block/nvme0n1p4, /sys/class/block/nvme0n1p6 exist, which lead to the partitions I've mounted. And my laptop contains only one SSD. It's manufactured by SK Hynix.

I think the trailing p hints at the partition number which would be next. So, I'm replacing the nvme0n1p in the commands you mentioned to nvme0n1. Correct me if I'm wrong.

I have found the problem. I will update the application tomorrow.

[govarthenan]

OK, I'm attaching the results you requested in the edited message as well. Please don't edit the comments as I can't give consistent information that way.

And where do I find that rpm_packaging.sh script?

[hakandundar34coding]

For v0.1.21-beta18, rpm_packaging.sh is in the main directory of the project. You can download this version from tags or releases links.

But for versions later than that it will be in packaging_scripts/rpm_packaging.sh directory.

I will update the application tomorrow and it will be in packaging_scripts/rpm_packaging.sh directory. Also 'disk stats' problem will be fixed.

Packages other than .deb wil be available for newer versions (RPM and pacman packages).

[govarthenan]

OK. GIve me a nudge after you update the app and I'll see if the problem has been fixed. Thanks.

[hakandundar34coding]

The code has been updated to fix this problem.

[govarthenan]

Commit 47d2c0c seems to have solved a few problems.

The Disk tab is showing metrics properly by default upon opening it. However, I observed that still, the default partition selected is the home partition. Also, the app is showing disk activity which happens only on the selected partition. When I tried copy pasting files within another partition, those metrics weren't shown in the app, which had the home partition selected. I don't know whether this is desired behavior.

Also, when I selected the SSD device, instead of a single partition, the disk space usage is shown NOT DISPLAYED.

[hakandundar34coding]

By default, System Monitoring Center selects system disk on Disk tab. But you can change this behavior from:
Main Menu > Settings > Remember last selected hardware
This is not a bug.

System Monitoring Center can also measure disk read/write speed, total read/write time of parent devices (SSD/HDD, USB devices, Virtual Devices, etc). You can select parent disk (SSD) and can view disk write/write speed when you copy a file from one partition to another one.
Can you share a video if you think there is a bug for showing disk speed of paren disk (SSD device)?

HDD/SSD device (parent of partitions) does not have a filesystem and disk usage of them can not be calculated. This is not a bug. You can view disk usage of the partitions by selecting them. The application wil show this information if selected disk is a partition.

But your disk model name is not displayed. There is a bug. Can you share output of this command?
cat /sys/class/block/nvme0n1/device/vendor

[govarthenan]

The specified directory doesn't have the vendor file.

However, the symlink devcice inside the folder leads to /sys/class/block/nvme0n1/device/device has the file 'vendor.

[gova@fedora ~]$ cat /sys/class/block/nvme0n1/device/device/vendor
0x1c5c

[hakandundar34coding]

Currently, the code can read only vendor file (not symlink). I will fix this problem.

[hakandundar34coding]

The code has been updated to fix the disk vendor name problem.

You can download Disk.py file (from: https://github.com/hakandundar34coding/system-monitoring-center/blob/master/src/Disk.py) and replace it manually (directory: /usr/share/system-monitoring-center/src/).

Can you write if the problem is fixed?

[govarthenan]

I tried to build the latest commit and I'm getting the following error:

[gova@fedora system-monitoring-center]$ ./packaging_scripts/rpm_packaging.sh
error: failed to stat /home/gova/gitclone/system-monitoring-center.spec: No such file or directory

I tried running as sudo and got the same result.
I reverted to fe07633 and tried building, which succeeded. But there is no SSD name to be seen.

[hakandundar34coding]

I have updated the code.
Can you try new Disk.py file? (You can download only Disk.py file and replace it instead of downlaoding the whole project). I will update the application and packages in 1-2 days.

[govarthenan]

I still keep getting that error:

[gova@192 system-monitoring-center]$ ./packaging_scripts/rpm_packaging.sh 
error: failed to stat /home/gova/gitclone/system-monitoring-center.spec: No such file or directory

I downloaded Disk.py and replaced it in /usr/share/system-monitoring-center/src/ and the name is still not displayed in the Disk tab.

[hakandundar34coding]

Disk device vendor-model information bug is fixed in the last update.

About rpm_packaging.sh script:
This file have to be run in a folder that one level under the main directory of the project. It works if you run it by opening terminal in the folder that contains this script file. By default, this script file is in /packaging_scripts folder. You do not have to change its location. Open a terminal in /packaging_scripts/ and run the script file.

RPM packages are uploaded for new versions of the application. You can download and install them easily.
