There are some useful tools in Unix/Linux to check out how the system is going on.

Here is a short summery of them:

This comes from a link below.

Let‘s see another one specifically which is neat to use when analysing TCP capture details

Notice: tool ‘tcprstat‘ is better to test the request/response timing durance and etc..

while tool ‘tcpstat‘ has something to do with its package capturing.

‘tcpdump‘ is another great tool which works with them.

TCP capture analysis and TCP analogy

For tool ‘tcprstat‘

Here‘s its github page: https://github.com/Lowercases/tcprstat/

To install ‘tcprstat‘ and ‘tcpstat‘

git clone https://github.com/Lowercases/tcprstat.git
cd tcprstat
chmod +x bootstrap
# if you are using debian/ubuntu/or ubuntu‘s derived destros, you would need to install package automake and autoconf
apt-get install automake autoconf -y
./bootstrap
#then
./configure --prefix=/usr/local # wherever the path you want
make
make install


# notice there are no package tcprstat in debian/ubuntu‘s software source repository. but they have the package ‘tcpstat‘. So,

apt-get install tcpstat -y

But I have to clearify that there are some errors in the ariticle that the author tried to

state the differences or the similarities between the tool ‘tcprstat‘ and the tool ‘tcpstat‘.

Actually his essay is all about the tool ‘tcprstat‘.

How to figure out the TCP package in an interactive chart?

He uses PHP, tcpstat and gnuplot to decorate the statistics.

Here‘s is the HOW-TO:

And it‘s tutorial from youtube:
