Ros2sysmon - a tool I created because I couldn't find one

[Pito Salas]

I built this little tool: https://github.com/pitosalas/ros2sysmon/tree/main

I know there must be something like this out there (in fact more than one) but I got tired of looking and it seemed like a fun little project. I hope someone tries it. And post issues if you want and I will look at them. It is open source (MIT).

[Sergei Grichine]

Pito,

It looks very promising, but I couldn't make it work on my Ubuntu 24.04 machine, Python 3.12.3

mkdir ~/tmp_ws/src
cd ~/tmp_ws/src
git clone https://github.com/pitosalas/ros2sysmon.git
cd ..
rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -r -y

(nothing new installed)

colcon build

ros2 run ros2sysmon ros2sysmon
...

ModuleNotFoundError: No module named 'textual'
sudo apt install python3-textual

(installs OK)

ros2 run ros2sysmon ros2sysmon

...

ModuleNotFoundError: No module named 'textual.containers'

The "textual.containers" is a new module that hasn't made it yet in the official Ubuntu "apt" distribution.

I tried it with venv:

:~/tmp_ws$ python3 -m venv venv
:~/tmp_ws$ source venv/bin/activate
(venv) :~/tmp_ws$ pip install textual

...

Well, it looks like Python VENV comes empty when it comes to ROS2 packages, and I didn't risk/bother to do rosdep install there.

Anyway, keep it up, thanks for your work!

Hmm. My setup is very similar… But I am running on the raspberry Pi on my robot.

I habitually run it with `ros2 run ros2sysmon run` but that’s just a stub that I wrote to save typing, it should be identical.

I likely did a pip install along the way that I forgot I did. Also when I do pip installs it always complains and I bypass the complaints with pip install break-system-packages. But that doesn’t sound like what you are seeing.

Let me look at it tomorrow.

Pito,

the following resolved my issue:

As I mentioned before, the issue is outdated "apt" package, missing the recently introduced "textual.containers" submodule. 

I'll play with it further. Thanks!

After I saw your problems, I rebuilt the python3-textual package from
25.04 (https://packages.ubuntu.com/plucky/python3-textual) and I at
least got most of the UI going;-) I was not running anything else 'ROS2'
on my laptop, that might explain some of the issues?!

See the attached screen shot.

Yeah, it looks like the version 2.1.1 is not 'new enough'. It's closer
than 0.1.13, but the output only really works with 6.1.0

[Marco Walther]

Pito,

I created a small pull-request to make it work with the textual 2.1.1
(from 25.04 - back-ported to 24.04). If that works for you, I can push
that back-ported package as well.

Thanks,
-- Marco

[Pito Salas]

Hi Marco, Sergei and Buddy…

Marco: "I created a small pull-request to make it work with the textual 2.1.1 (from 25.04 - back-ported to 24.04). If that works for you, I can push that back-ported package as well.“

Pito: "Yes it worked for me, and accepted the pr. Three of you tried it and all had a similar problem (see below the line). I would like this to be more robust but I am not sure how to do it. Is it a change to package.xml, or CMakelists.txt or something else? If you know please say or generate a PR. Secondly I would love it to be installable with pip alone and I believe this is possible. I was going to research this but again if any of you know then please say or send a PR.

From a functionality point of view, I have two concerns which you could keep an eye out for: are the numbers “correct”? And how much load does the tool itself put on the system.

Of course any features that dont work right or you would like me to add, please send them too.”

Thanks for your interest!

Pito

  "I tried to use the package, but I had python issues.  I do have Python3 installed, but I'm not too familiar with using python packages.
This is on Ubuntu 24.04LTS and ROS2 Jazzy, Python 3.12.3

It built ok, but when I tried to run, I got error messages about missing pyton textual,
   so I first tried to install by
   pip install textual
   First I had to install pip with
        sudo apt install python3-pip

   Then I tried again
    pip install textual
   and got an error: externally-managed-environment
   so installed textual by  
sudo apt install python3-pip

    then I got errors about missing textual.containers

Traceback (most recent call last):

  File "/home/jwf/Downloads/ros2sysmon-main/install/ros2sysmon/lib/ros2sysmon/ros2sysmon", line 3, in <module>

[Sergei Grichine]

I'd guess that a note in the README will be sufficient:

Note: for Ubuntu 24.04 or other systems having older versions of "textual" package do: 

    sudo apt remove python3-textual

    pip3 install --break-system-packages textual

[Pito Salas]

What I actually meant installing ros2sysmon fully with pip vs. git clone. Do you think that’s worth while? Also is there a way to have colcon build install textual itself or is that out of scope?

I want to make it painless and reliable to install.

THanks!

Pito

Yeah, but with many exclamation marks! That's the 'quick & dirty
solution', which might break other things (or might be broken by other
things):-(

That's why I went the other way and tried to use 'released (2.1.1) or
upcoming (2.1.2 currently in 25.10)' packages and make things work. That
way, the system stays [mostly] consistent even when installing new
software or upgrading;-)

[Sergei Grichine]

With ROS2, "git clone -> apt install -> colcon build" is a way of life. People (me) learn it early, and that's sufficient for 99.99% of ROS2 work. For Python dependencies, "sudo apt install python3-<pkg>" works very well.

I actually learned about "pip3 install --break-system-packages" yesterday (thanks, Pito!) - it is useful, but a bit of a crutch. Acceptable (not in sudo mode, IMHO). Pip and Python aren't ROS2 natives, most of it is C++

I'd keep it traditional and simple. Good as-is already. Maybe, only deserves a close look at "depends" list.

And, of course, Marco's PR makes total sense IMHO 

[Pito Salas]

I agree about —break-system-packages. It sounds scary. But what is the correct way to install it? I wasn’t sure about asking to create of virtualenv because, would normal ros2 run properly run from the .env?

Does anyone know the “right” way to do this?

And did that fix the need to do the —break-system-packages?

[Michael Wimble]

How about using a separate python virtual environment to solve it? Isn’t that what it’s for?

I don't think so:-( You would have to pull a lot of ROS into your pip
package and now you end up with mostly 'two ROS installations' and as
far as I know, not much support from the environment:-(

You could try to create a ROS package, similar to all the other
ros-jazzy-....deb's and find a way to distribute that. That would
preserve the dependency framework and play nicely with the rest of the
packages (and your work spaces).

> Also is there a way to have colcon build install textual itself or is that out of scope?

That could probably be done. ROS already replicates some system
libraries. So, the infrastructure is probably in place. But you rn into
the same 'coordination requirement' once you have more packages
depending on those libraries.

The bigger question is, how many pieces do you want to maintain and keep
updating for the next ten years? The textual from 25.04 now works just
fine as far as I have seen. So, the next LTS 26.04 will 'just work', and
28.04 might already be ahead of your textual version.

Just my take,
-- Marco

[Pito Salas]

Ok, thanks everyone! I think I will leave it as is and see how it goes. If you end up using it… My two questions: do the numbers make sense (e.g hz which I messed around a bit) and does the tool itself use too much cpu?

Note three things:

- There are two “pages” that you switch back and for the between them with typing 1 and 2
- There is a yaml file with a many configurable parameters
- There is an “r” command to force a refresh

Not yet. But once I push the python3-textual package from 25.04 to my
PPA for 24.04, you can just install that and be done with it.

Do I add info to my readme to tell them how to adopt your ppa? Can you say the instructions (again?)

The instructions are at
https://launchpad.net/~marco-sonic/+archive/ubuntu/rasppios

The description of the PPA says for Raspberry Pi, but the textual
package is classified for 'all' architectures, it's just Python3 code;-)
The PPA is 'safe' to add to x86_64 hosts;-) The Debian packaging
infrastructure is smart enough to consider only 'compatible' packages;-)

I pushed the sources and the package is currently building. It should be
available in about an hour.

[Steve " 'dillo" Okay]

Nice!

I just gave you your first "star" on Github! 

Nice work...

'dillo

[Pito Salas]

Indeed my first, thanks! Did it install and work ok for you?
