HTTPing

[Vinil]

Httping monitoring tool is like ‘ping’ but for http-requests. Give it an url, and it’ll show you how long it takes to connect, send a request and retrieve the reply (only the headers). Be aware that the transmission across the network also takes time! So it measures the latency of the Webserver + network.

How to install


You can install it through yum

yum install httping

or try with rpm repository.

http://pkgs.org/centos-6-rhel-6/repoforge-x86_64/httping-2.0-1.el6.rf.x86_64.rpm.html

Install via source

Code: [Select]

cd /usr/local/src

http://www.vanheusden.com/httping/httping-2.3.3.tgz

tar -zxvf httping-2.3.3.tgz
cd httping-2.3.3

make install

This will first invoke the 'configure'-script and then build the sources.
You can also run 'configure' manually. Then the following switches apply:
--with-tfo      force enable tcp fast open
--with-ncurses  force enable ncurses
--with-openssl  force enable openssl
--with-fftw3    force enable fftw3

Please note that TCP fast open requires a Linux kernel of version 3.7 or more recent.

'fftw3' support is only usefull if you include the ncurses interface.

Now ping your website.

Code: [Select]

root@server1 [~]# httping -g www.example.com

Ping a Webserver and Specify a port: ( specify port 80 )

Code: [Select]

root@server1 [~]#$ httping -c 4 -p 80 -g http://www.example.com

Ping a Webserver and request complete page/file:

The capital “G” sends a GET request rather then a HEAD request. By receiving the entire page/file you can measure the throughput of the webserver.

Code: [Select]

root@server1 [~]# httping -c 4 -p 80 -G -b -g www.example.com
PING example.com:80 (/):
