We can by setting the variable "SA_DIR" to define a new directory sa1 and sa2 use.
In the Linux environment to install Sysstat
This "Sysstat" Of course you can get the package and installed in the main Linux distribution's package repository. However, the software library packages obtained from a narrow version and an older version. So, this is why we want to host the official website to download and install the latest version (11.0.0) grounds in the package.
First of all, please use the following link to download the latest version of sysstat package, or you can download wget commands directly in the terminal.
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 then enter the directory and start the compilation process.
# Tar -xvf sysstat-11.0.0.tar.gz
# Cd sysstat-11.0.0 /
At this point, there are two options:
a) First, you can use iconfig command (which will let you set each parameter promising free custom values).
# ./iconfig
b) Second, you can define the options for a single command line using the standard configure command. Is run ./configure -help to get a list of command options are supported.
# ./configure --help

Here, we use the standard options that the use ./configure command to compile the sysstat package.
# ./configure
# Make
# Make install
After compilation, you will see output similar to the above. Now verify sysstat version by running the following command.
# Mpstat -V
sysstat version 11.0.0

Update Sysstat in Linux systems
By default, the compiler will install the package in / usr / local "directory. Therefore, all binary / public file will be installed in" / usr / local / bin "directory. If you have installed the package sysstat , you can find those files directly in "/ usr / bin" in.
If you have already installed the sysstat package and your system "$ PATH" variable is not added to "/ usr / local / bin", then you will not receive tips about the updated version. So the compiler or remove the existing version before updating process, make sure to check the "$ PATH" variable good system has been set up "/ usr / local / bin" or been able to -prefix option to configure the "/ usr "content.
# Yum remove sysstat [On RedHat based System]
# Apt-get remove sysstat [On Debian based System]
# ./configure --prefix = / Usr
# Make
# Make install
Now, using the same "" mpstat command and the "-V" option again to confirm later.
# Mpstat -V
sysstat version 11.0.0
