CPU Heatmap Generator

This repository uses the seaborn module in python to create a heatmap of each CPUs Utilization over a specified period of time.

Requirements

A. Python3 Libraries

1. Matplotlib
2. Seaborn
3. Numpy

B. System Activity Report (SAR) tool on Linux

Usage

./Parser.sh <CSV CPU List> <Timespan> 
./Parser.sh 0,1,2,3,4,5,6,7 10

The heatmap obtained will look something like this.

Here the X-axis is a plot of the timespan specified (10s) and the Y-axis corrosponds to the Number of Cores. This heatmap indicates individual CPU utilization during every second of the workload.

To change the number of cores, open CPU_Heatmap.py and change the value of numCPU

Example of a 1 minute workload on a 32-Core (Logical) machine
