graphsar

SAR Graph plotter Tool. The following data are plotted using the SAR logs

• CPU usage
• Load average
• RAM usage
• I/O transfer
• Processes created per second
• Context switches
• Tasks (run queue, active, blocked)
• Network interface statistics (eth0 by default)
• TCP/UDP sockets

Inspired by the following Link : https://github.com/juliojsb/sarviewer

Requirements

• Existing SAR Logs
• Windows Subsystem for Linux (Ubuntu). Location : Microsoft Store
• Xming Server for windows. Download Link : https://sourceforge.net/projects/xming/
• Update the existing repository in Windows Subsystem for Linux (Ubuntu)

apt-get update --fix-missing

• Install the following packages using the following command

apt-get install python sysstat python-dev python-tk python-matplotlib

• Git for source control.
• Download the graphsar package using git

git clone https://github.com/sribs/graphsar

Usage

• Launch the Xming application on Windows
• set the display parameter in the Windows Subsystem Ubuntu

export DISPLAY=:0

• Go to the directory where it is cloned from git.
• open the File graphsar.properties.
• set the default readings :

# Log dir where sa* files are stored# By default folder /var/log/sysstat
sysstat_logdir="/var/log/sysstat"# Variable network_interface specifies the interface for netinterface statistics graph# By default, eth0
network_interface="eth0"# Default start time to parse statistics
start_time="00:00:00"# Default end time to parse statistics
end_time="23:59:59"

• Run the file read_existing.sh using the command

./read_existing.sh

• If this command is already performed, no need of running the above command. Instead run this command

./plotgraph.sh

• This will open an interactive window where we can zoom the graph and derive accurate conclusions.

• The above operation will get the details from the existing SAR file location in graphsar.properties file

• All the images are stored in graphs folder. This can be shared over an email.

Next Release

• Planning to integrate HTML support with this.
