knetstat - network i/o statistics like iostat for Solaris 10

I wanted a tool to show up network i/o statistics - just like iostat does for disk access. I used Sun::Solaris::Kstat in Perl, available in Solaris 10 package SUNWperl584core.

The only paramter my script accepts for now is the time delay between two measurements.

Example:

-bash-3.00$ knetstat 2
            network i/o statistics
       r/s        t/s        kr/s        kt/s  interface
            network i/o statistics
       r/s        t/s        kr/s        kt/s  interface
      1086       1916       91.75     2400.10  e1000g0
      45.5       48.5        6.78        8.51  e1000g1
            network i/o statistics
       r/s        t/s        kr/s        kt/s  interface
    1129.5       1921       99.30     2396.48  e1000g0
      17.5         18        2.46        2.59  e1000g1
            network i/o statistics
       r/s        t/s        kr/s        kt/s  interface
     706.5       1063       79.56     1199.68  e1000g0
        16         18        2.43        2.63  e1000g1
