Here is what I have done so far. In the network init script I have added the following...
echo $(date +%s.%3N; cat /sys/class/net/$EXTIF/statistics/rx_bytes; cat /sys/class/net/$EXTIF/statistics/tx_bytes) "stop" >> /var/log/$EXTIF-meter.txt right before the ip link set dev $EXTIF down. I did the same for EXT2IF and a "start" log immediately after every place the EXTIF/EXT2IF is brought up. Then I added the following to crontabs... 59 * * * * echo $(date +%s.%3N; cat /sys/class/net/eth0/statistics/rx_bytes; cat /sys/class/net/eth0/statistics/tx_bytes) "cron" >> /var/log/eth0-meter.txt 59 * * * * echo $(date +%s.%3N; cat /sys/class/net/eth2/statistics/rx_bytes; cat /sys/class/net/eth2/statistics/tx_bytes) "cron" >> /var/log/eth2-meter.txt Is there a way to get $EXTxx variables in crontabs? After rebooting and waiting for the big hand to point at the number 12, here is my eth0 log... pbx kd # cat log/eth0-meter.txt 1611696594.726 41916587023 8211080131 stop 1611696625.644 0 0 start 1611698340.940 832008278 51755144 cron So now I think I can just gather all the data and I should be able to create a script to read and sum things up... last hour, last day, last week, last month, whatever. Could probably import to excel for fancy graphs. But patience required, will have to wait a while before I have enough data to play with. I suppose I could do this for INTIF's as well.
