Collect and plot system statistics such as CPU utilization and disk utilization metrics.

Prerequisites

You need to install python3 and matplotlib

sudo yum install python3
sudo yum install python3-pip
pip3 install matplotlib

Edit the ./extract-data.sh and fix the path to the disk_util.sh file:

"$(pwd)"/system_util/disk_util.sh \
	-b "${RESULT_DIR}"/diskstats-before-* \
	-a "${RESULT_DIR}"/diskstats-after-* \
	-s "${RESULT_DIR}"/iostat-* \
  -r "${RESULT_DIR}" \
  "${DEVICES[@]}"

Edit the ./disk_util.sh and fix the path to the plot_iostat.sh file:

"$(pwd)"/system_util/plot_iostat.py \
  -i ${IOSTAT} \
  -o ${RESULT_DIR}/plots \
  -s ${DEVICES[0]}

Configure

Before run set in disk_util.sh file the devices that you want to get metrics by setting DEVICES variable.
