Network statistics reset

[kropochev]

The problem is described on the link http://raspberrypi.stackexchange.com/questions/12277/network-statistics-reset

Can go to vnstat? And to add a bit rate in real time?

I didn't knew this software. Interresting tools indeed. We could imagine an addons displaying image generated by vnstati or use it directly as a source of information for RPi-Monitor with vnstat --oneline and a correctly shapped regular expression.

dynamic.10.name=net_received
dynamic.10.source=vnstat -i eth0 --dumpdb
dynamic.10.regexp=totalrx;(\d+)
dynamic.10.postprocess=$1*1024*1024*-1
dynamic.10.rrd=DERIVE
dynamic.10.max=0

dynamic.11.name=net_send
dynamic.11.source=vnstat -i eth0 --dumpdb
dynamic.11.regexp=totaltx;(\d+)
dynamic.11.postprocess=$1*1024*1024
dynamic.11.rrd=DERIVE
dynamic.11.min=0

Advantages over the old version, no data are reset after reboot. Disadvantages, accuracy 1MB and the default data in the database is updated every 5 minutes, but in the config /etc/vnstat.conf you can change the update time per minute.

# how often (in minute) data is saved to file
SaveInterval 1

This is indeed good for keeping net stats between reboo, but there's an issue with graphs: the values drawn are wrong. Right now I have a 2MBps up (FTP conn), but the graph goes as high as 60MBps while using vnstat, which is not possible. Also, using "SaveInterval 1" makes is go over 500MBps... Is it possile to fix this? Thanks.

In new versions of vnstat --dumpdb doesn't work anymore, the solution is

dynamic.1.name=net_received dynamic.1.source=vnstat --json -i eth0 | jq '.interfaces[0].traffic.total.rx' dynamic.1.postprocess=$110241024*-1 dynamic.1.rrd=DERIVE dynamic.1.max=0

dynamic.2.name=net_send dynamic.2.source=vnstat --json -i eth0 | jq '.interfaces[0].traffic.total.tx' dynamic.2.postprocess=$110241024*-1 dynamic.2.rrd=DERIVE dynamic.2.min=0
