I have installed via plugin manager, and run the configuration command however the network health plugin does not appear to function. I have checkd my logs and find the following:

2021-05-08 07:23:08,260 - octoprint.plugins.networkhealth - ERROR - Could not run network health check
Traceback (most recent call last):
File "/home/pi/oprint/lib/python3.7/site-packages/octoprint_NetworkHealth/init.py", line 18, in _check_network
if not self.check_ping():
File "/home/pi/oprint/lib/python3.7/site-packages/octoprint_NetworkHealth/init.py", line 54, in check_ping
response = os.system("ping -c 4 " + hostname)
TypeError: can only concatenate str (not "NoneType") to str

and it just keeps looping.
Any suggestions?

Hello,

(This was made as of bee1bd9)

Just was poking at this plugin and wanted give you a heads up on a few things:

• Your current release version 1.0.0 doesn't run on OctoPrint and will never receive updates. You might want to push 1.0.1 or retag 1.0.0 to a newer working commit
• While not explicitly required you should move these into the NetworkHealthPlugin class.
• Finally, while it may not be logged; changes made via the ip command require root privileges. So as it stands when those commands are run they do not actually do anything. In order for this to work the plugin would need elevated privileges via sudo. By default on OctoPi the pi user does not have sudo rights to the ip command so the user would need to manually configure that. Take a look at /etc/sudoers and /etc/sudoers.d Example ip command error below:

pi@octopi:~ $ ip link set eth0 down
RTNETLINK answers: Operation not permitted

Looks like the metadata for this plugin is still 1.0.0 so even though installed or updated to 1.0.2, it's constantly asking to install an update.

I was having issues with my Pi overheating and I just dove into the cause. Turns out the Pi (a 3B+) had a permanent load of 2.5 when idle. Turning on safe mode resolved that issue so I looked into my plugins. I uninstalled one of the non-stock plugins that I was using but it didn't fix anything, so I only had the Network Health plugin left to check, and sure enough, disabling it gave me normal load levels.

This was before I turned off the Network Health plugin:

This was after:

Literally the only difference between the two is whether or not Network Health is enabled.

I should probably add that I did properly install the plugin including the sudoers configuation, unless there is more to it than the readme suggests.

I've used this plugin for quite a while, and was very happy with it until recently. The Pi exhibits it's old behavior, which is that it disappears from my network from time to time. It still seems functional, as prints continue to completion, I'm just unable to see the web interface or connect with PuTTY.

I don't know if there's a configuration problem since an OctoPi reinstall a ways back, or if there's some other issue. I'll be happy to provide whatever information I can to help diagnose. I am able to put a screen/keyboard on my Pi, although I don't have it set up that way at the moment.

Users of OctoPi image will need to install the iproute2 package for this to work. it contains the 'ip' command required for this plugin to work.

Command to install:
apt install iproute2

I think this is due to the fact that your command is the username pi which is not my username but I would like some confirmation.
