NAME
lnstat - unified linux network statistics SYNOPSIS
lnstat [options] 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 sup- ports any kind of statistics the linux kernel exports via a file in /proc/net/stat/. OPTIONS
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. USAGE EXAMPLES
# lnstat -d Get a list of supported statistics files. # lnstat -k arp_cache:entries,rt_cache:in_hit,arp_cache:destroys Select the specified files and keys. # lnstat -i 10 Use an interval of 10 seconds. # lnstat -f ip_conntrack Use only the specified file for statistics. # lnstat -s 0 Do not print a header at all. # lnstat -s 20 Print a header at start and every 20 lines. # lnstat -c -1 -i 1 -f rt_cache -k entries,in_hit,in_slow_tot Display statistics for keys entries, in_hit and in_slow_tot of field rt_cache every second.

Convert vnstat log to csv
