unix - Reading Incoming Mbit/s in plaintext with Perl -


I can not find any solution for this, I want to read the incoming MBT / S on the interface in Perl. I am just trying to report Perl script as MBT / S: 9.66 It will be as if I have a network of 9.66 MB / s.

I tried to use VNNastat and parse the characters. But no benefit.

If you are on a Linux system, then there are usually sub directories in / sys / : 

  / sys / class / net / eth0 / statistics   
 If you can depend on that current constant (/ sys /) in kernel 2 , Then you should be fine), "files" in that directory can be used to create some statistics on the interface, including incoming (Rx) bytes in that interface.  
 Here is a  extremely  crude example:  
  Usage list :: UTL qw (amount); My @bytes; (1..11) {open (FH, "& lt;", "/ sys / class / net / eth0 / statistics / rx_bytes") or die $ @; Push (@bytes, & lt; fh & gt;); Sleeping 1; Close (FH); } My @bytes_per_second; (1..10) {my $ diff = ($ bytes [$ _] - $ bytes [($ _ - 1)]); Push (@bytes_per_second, $ diff); } Print amount (@ bytes_per_second) / @ bytes_per_second;   
 The above code will give you an average [bytes] of the average data per second (seconds) in the interface called "atte". There are great ways to improve this performance, which I do not think are necessary for this performance, but using a timer and reading it separately from the file.  
 Hope this will prove useful to you, but if you are not on Linux, then unfortunately it will be completely useless.

The circuit has the following specifications: The present value of swift SW15-0 on the D2 board should be shown in four hexadecimal four sections of HEX3-0. This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo
