Installation of Sysstat in Linux

First download the latest version of sysstat package using the following link or you may also use wgetcommand to download directly on the terminal.

  1. http://sebastien.godard.pagesperso-orange.fr/download.html
# wget http://pagesperso-orange.fr/sebastien.godard/sysstat-11.0.0.tar.gz

Next, extract the downloaded package and go inside that directory to begin compile process.

# tar -xvf sysstat-11.0.0.tar.gz 
# cd sysstat-11.0.0/

Here you will have two options for compilation:

a). Firstly, you can use iconfig (which will give you flexibility for choosing/entering the customized values for each parameters).

# ./iconfig

b). Secondly, you can use standard configure command to define options in single line. You can run./configure –help command to get list of different supported options.

# ./configure --help



Here, we are moving ahead with standard option i.e. ./configure command to compile sysstat package.

# ./configure
# make
# make install		

After compilation process completes, you will see the output similar to above. Now, verify the sysstat version by running following command.

# mpstat -V

sysstat version 11.0.0

Updating Sysstat in Linux

By default sysstat use “/usr/local” as its prefix directory. So, all binary/utilities will get installed in “/usr/local/bin” directory. If you have existing sysstat package installed, then those will be there in “/usr/bin”.

Due to existing sysstat package, you will not get your updated version reflected, because your “$PATH” variable don’t have “/usr/local/bin set”. So, make sure that “/usr/local/bin” exist there in your “$PATH” or set –prefix option to “/usr” during compilation and remove existing version before starting updating.

# yum remove sysstat			[On RedHat based System]
# apt-get remove sysstat		[On Debian based System]
# ./configure --prefix=/usr
# make
# make install

Now again, verify the updated version of systat using same ‘mpstat’ command with option ‘-V’.

# mpstat -V

sysstat version 11.0.0
