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 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. | |
USAGE EXAMPLES
# lnstat -d | |

# lnstat -f ip_conntrack | |
