I have solved. this problem. Thanks to everyone that viewed.
I am connecting top the router from a Raspberry Pi using SSH. Using the command:
ssh_client.exec_command("cd /usr/bin")
stdin,stdout,stderr = ssh_client.exec_command("vnstat -m 1 --oneline")
I then slice the output to grab the necessary information and port it to my MQTT broker.
from vnstat.
It would be polite to also explain your solution. There aren't that many more annoying things on the Internet than looking for a solution for a problem, finding out someone else has also been having the same problem and solved it but without telling how.
For your specific scenario, there are several options depending on what is most suitable for the followup implementation:
- Assuming OpenWRT has implemented also the json api, you could query it via http(s) and get that information remotely. If this hasn't been made available then maybe a feature request towards OpenWRT could help.
- With command line access you can query
vnstat --json m 1 -i wan
for getting the output for only the currently ongoing month in json format for the wanted interface (wan in this case). Then extend this withjq
to get the sum of rx and tx values resulting in the full command beingvnstat --json m 1 -i wan | jq .interfaces[0].traffic.month[0].rx+.interfaces[0].traffic.month[0].tx
. Obviously if you are using python to read thevnstat
command output then there's no point usingjq
for parsing the correct content since python will be more than capable on doing that too. - With command line access, instead of
--json
, use--oneline
instead and extra the 11th field containing the current monthly data and instruct--oneline
to use bytes:vnstat --oneline b -i wan | cut -d\; -f11
- Read the vnstat.db sqlite file directly with sqlite cli or python. I wouldn't however suggest using this method.
Things not suggested to be done:
- OCR with the image
- Parsing any "intended for humans" plain text
vnstat
output
from vnstat.
