Allows ss (socket statistics) to continously output microsecond timestamped
procfs information about current TCP connections. Based on iproute2 "ss -
another utility to investigate sockets."
Usage:
ss -g
Install:
sudo apt-get install iptables-dev
./configure
make
Output:
When using the -g option, ss will output data like the following example. The
delimiter between continuous procfs reads is the TIMESTAMP keyword. mono and
real correspond to the timestamps logged using clock_gettime (see `man 2
clock_gettime`).
TIMESTAMP
mono 1296043 253642430
real 1330444244 341364392
