Vnstat support by Netdata #9304

Open startryst opened 4 years ago

This is same as #3756 , but would like to see any possibility to make it happen.

Hi

https://linux.die.net/man/1/vnstat

vnStat is a console-based network traffic monitor. It keeps a log of hourly, daily and monthly network traffic for the selected interface(s). However, it isn't a packet sniffer. The traffic information is analyzed from the proc(5) and sys filesystems depending on availability. That way vnStat can be used even without root permissions on most systems.

I think we already collect network traffic from proc.

Can you elaborate a bit? I didnt read #3756 carefully, but since it is a new issue it would be nice to have more or less detailed description what you ask.

So, let me share this to you as the outcome what I'm trying say:

So as you see above, through vnstat, we can get a aggregate of how many bytes has been transferred, rather than the real-time one, would be nice if we can get similar output from netdata.

ndt8552 commented 4 years ago

Is there any update on this? My company uses vnstat and this will be very useful to us.

ilyam8 commented 4 years ago

@ndt8552 there is a pr with the plugin

https://github.com/netdata/netdata/pull/8955

You can test it, would be nice
