lan-bps chart

[sfs-pra]

I want to change the lan-bps.widget “label” to “chart”.
What is 100% ?
If you take as 100% ip link show eth0 |head -n1|awk -F qlen '{print $2}' - the chart will be at zero all the time
You could take the number of bits per minute as 100%. I don't understand how to get it in widget

The answer would depend on what you're trying to display. I assume you're looking to graph the receive transmission rate. There is really no well defined upper limit you can use. You could use your adapters max rate, but I think your actual rates would be way too low vs that to get a meaningful graph. Possibly the most reasonable graph you can plot is the current tx rate vs max recorded tx rate for the session. It would be a bit fiddly to implement, but should be possible.

Set EthRcvdMax1 = If(EthRcvd1 >= EthRcvdMax1, EthRcvd1, EthRcvdMax1)

When “rcvd” is changed to “sent” - the whole chart is recolored

For another implementation I've gone with a default min cap of 50 kb/s and otherwise max bw for the values represented in the history to mean 100%. The min cap ensures that values like 0.5 kb/s don't show up as 100% if there is otherwise no noticeable network traffic. So essentially something like max_bw = max(50*1024, max(history_values)).

How about this?

file("/proc/net/dev") {
  EthRcvd = RegEx("^(?!.*lo).*:[\t ]*([0-9]+)",Sum)
}

Set LanBPS = (EthRcvd-EthRcvd.pval)/0.001024/EthRcvd.time
Set LanMax = Max(Max(50, Cached(LanMax)), LanBPS)

layout {
  chart {
    style = "cpu_chart"
    interval = 1000
    value = LanBPS/LanMax
  }
}

How about this?

perfectly

EthRcvd = RegEx("^(?!.lo).:[\t ]*([0-9]+)",Sum)

And if two interfaces eth0 wlan0 ?

[LBCrion]

This will sum up the traffic across all interfaces other than lo. If you want a specific interface, you can replace !.lo with interface name.

Here either draw 2*chart or wait for a chart with two charts to appear :)
