How libxo do it easier?
netstat can be accept multiple interface name in 'netstat -nbI'?
gstat can be run to pipe?
igb show statistic in netmap mode?
Multiple statistics collect at same time (in one fraction second)?
I am don't need web output, in most case plain tabular data enough.
In most cases on wanted serever exist only ssh, no web, no python, no
R, no gnuplot.

Also, how to convert to libxo D scripts? or zfs-stat?
