Two python errors when running interactively
Hi!
I'm trying to get a monitor up on my rpi to understand when it's down, so I can understand what the root cause is. imon seems like a great fit for this.
I've gone through the configuration (see output below). But when I try to run the script I get the following error. Mind helping me troubleshoot?

NameError: name 'ifda' is not defined. Did you mean: 'ifdat'?
Python is correct, that ifda should be ifdat. Not sure about the first one yet.
Will spend some time on this today after breakfast.
Thanks for giving imon a go, and for the feedback. Stay tuned.
Both of your issues (icmplib doc and python errors) are corrected with updates on this GitHub.
You should be able to rerun imon-install, which will download the updated files and configure the python venv that imon now uses.
Please LMK how your testing goes.
Hi, I had the same issues when I tried this a week ago. For me, the latest commit works! Thank you!
However, I would like to note that on my rpi (3 Model B+, running Raspberry Pi OS Bookworm), i needed to manually install pip3 using sudo apt install python3-pip (not sudo apt install pip3).
Also, in order to test-run imon after setting up the config file with sudo imon configure, I could not simply use sudo /usr/local/bin/imon --nosyslog --instance MY_INSTANCE_NAME, as it doesn't seem to use the venv configured during install:
Traceback (most recent call last):
File "/usr/local/bin/imon", line 7, in <module>
from icmplib import ping, multiping
ModuleNotFoundError: No module named 'icmplib'
Instead, I copied the command from the service and ended up with the following:
sudo /root/.imon-venv/bin/python /usr/local/bin/imon --nosyslog --instance MY_INSTANCE_NAME
This did work to run imon interactively!
@minimusubi Thx for your report. I updated the README to have the correct example command for testing (using the venv), and corrected the installer to install python3-pip rather than pip3.
