description
This manual
page documents briefly the lnstat command.
lnstat
is a generalized and more feature-complete replacement for
the old rtstat program. In addition to routing cache
statistics, it supports any kind of statistics the linux
kernel exports via a file in /proc/net/stat/.
options
These programs
follow the usual GNU command line syntax, with long options
starting with two dashes (’-’). lnstat supports
the following options.
-h, --help
Show summary of options.
-V,
--version
Show version of program.
-c,
--count <count>
Print <count> number of
intervals.
-d,
--dump
Dump list of available
files/keys.
-f, --file
<file>
Statistics file to use.
-i,
--interval <intv>
Set interval to
’intv’ seconds.
-k, --keys
k,k,k,...
Display only keys
specified.
-s,
--subject [0-2]
Specify display of
subject/header. ’0’ means no header at all,
’1’ prints a header only at start of the program
and ’2’ prints a header every 20 lines.
-w,
--width n,n,n,...
Width for each field.
