-lnstat - linux networking statistics
-(C) 2004 Harald Welte <laforge@gnumonks.org
-======================================================================
-
-This tool 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. In a stock 2.6.9
-kernel, this is
- per-protocol neighbour cache statistics
- (ipv4, ipv6, atm, decnet)
- routing cache statistics
- (ipv4)
- connection tracking statistics
- (ipv4)
-
-Please note that lnstat will adopt to any additional statistics that might be
-added to the kernel at some later point
-
-I personally always like examples more than any reference documentation, so I
-list the following examples. If somebody wants to do a manpage, feel free
-to send me a patch :)
-
-EXAMPLES:
-
-In order to get a list of supported statistics files, you can run
-
- lnstat -d
-
-It will display something like
-
-/proc/net/stat/arp_cache:
- 1: entries
- 2: allocs
- 3: destroys
-[...]
-/proc/net/stat/rt_cache:
- 1: entries
- 2: in_hit
- 3: in_slow_tot
-
-You can now select the files/keys you are interested by something like
-
- lnstat -k arp_cache:entries,rt_cache:in_hit,arp_cache:destroys
-
-arp_cach|rt_cache|arp_cach|
- entries| in_hit|destroys|
- 6| 6| 0|
- 6| 0| 0|
- 6| 2| 0|
-
-
-You can specify the interval (e.g. 10 seconds) by:
-
- lnstat -i 10
-
-You can specify to only use one particular statistics file:
-
- lnstat -f ip_conntrack
-
-You can specify individual field widths
-
- lnstat -k arp_cache:entries,rt_cache:entries -w 20,8
-
-You can specify not to print a header at all
-
- lnstat -s 0
-
-You can specify to print a header only at start of the program
-
- lnstat -s 1
-
-You can specify to print a header at start and every 20 lines:
-
- lnstat -s 20
-
-You can specify the number of samples you want to take (e.g. 5):
-
- lnstat -c 5
-
