All network info is collected from /proc/net/dev
when using linux in both psutil
and /proc
methods.
You're not running bashtop sandboxed or something like that?
Otherwise i would try while downloading something or running a speed test, to see if there's something going wrong in there.tail -f /proc/net/dev
tail
is not going to work i realized. But running cat /proc/net/dev
a couple of times during and comparing.
Are you running multiple network monitor software? Was thinking that it might not get access possibly if something else is constantly reading from /proc/net/dev
.
cat /proc/net/dev
seems to work correctly:

But bashtop reports this:
I cannot find any issue with accessing /proc/net/dev
nor am I running sandboxed. As I say, it occasionally works but not always.
eth1 currently seems to be working.
Not really sure how to debug this, since it's not crashing and there is nothing showing in the error log it doesn't point to being an error caused by bashtop. It rather looks like it fails to read /proc/net/dev
which would indicate it being locked at times for some reason.
Is there any difference if you switch to psutil
data collection?
I just tried and when attempting to change to psutil
it reloads and sticks with "use psutil" false
.
You need python 3.6 or greater and psutil module. Can be installed with pyton3 -m pip install psutil
.
Is there any difference if you switch to
psutil
data collection?
That seems to work:
I too had to switch to psutil - one thing I noticed, if I started it with sudo the info displayed correctly (with psutil set to false. FYI - I'm running it as a snap.
Describe the bug
I can be transferring huge amounts up and down and the network section for the correct interface (eth0) shows no traffic whatsover.
To Reproduce
Seems to happen about 40% of the time. Relaunching makes no difference.
Expected behavior
Sometimes it reports network traffic fine.
Screenshots
this is network traffic reported by netdata
this is network traffic reported by bashtop
