lnstat − unified linux network statistics
lnstat [options]
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/.
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.
# 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.
