Hi I want to monitor my network traffic ( Recived / Sent data per seconds) .

like the windows network traffic . `sent 152k/s``recived 8k/s` .

but the network dashboard . `out243.774m/30s``in 166.448m/30s`

 ![](https://us1.discourse-cdn.com/elastic/original/3X/7/2/72498432a0b8bb238f17f87deb4ce6ade267f750.png)

may be (out\_bytes2 -out\_bytes1)/30s ? like (267.722Mb - 267.698Mb)\*1024/30s=  
0.8192k/s ?

in the source code ,[network/network.go#L85-L99](https://github.com/elastic/beats/blob/master/metricbeat/module/system/network/network.go#L85-L99) and it's dependent [net/net\_windows.go#L49-L50](https://github.com/shirou/gopsutil/blob/master/net/net_windows.go#L49-L50) .

I think what you are looking for are the derivatives of the total byes in and out (which you have above). Best use Timelion to add a such a visualisation to your dashboard: [https://www.elastic.co/blog/timelion-timeline](https://www.elastic.co/blog/timelion-timeline)
