Licence Plots

Scripts to record and plot hourly use of Mathematica and Matlab network license usage

Prerequisites

Need to have R installed: https://cran.r-project.org/ Need to have the following packages in R installed:

• lubridate
• ggplot2
• gridExtra
• zoo

File Descriptions

• MatlabLicScript - Takes in current date, time & Matlab licenses being used and appends them to MatlabLicStat.txt in CSV format.
• MathematicaLicScript - Takes in current date, time & Mathematica licenses being used and appends them to MathematicaLicStat.txt in CSV format.
• licensePlots.R - Plots Matlab and Mathematica licenses used each month for the last 12 months and outputs it to lic-usage-plot.png
• (optional) lic-usage.php - Website displaying plot

Installation

• Put MatlabLicScript and MathematicaLicScript in whichever directory you want. Let's call that path to that directory [exePath]
• Put licencePlots.R in whichever directory you want. Let's call that path to that directory [dataPath]
• Create two empty text files in [dataPath] and call them "MatlabLicStat.txt" and "MathematicaLicStat.txt"
• In all 3 files (licencePlots.R, MatlabLicScript and MathematicaLicScript) replace "[dataPath]" with the above path, and "[matlabPath]", "[flexnetPath]" and "[wolframPath]" with the respective directory paths of the matlab, flexnet and mathematica license manager.
• Make MatlabLicScript and MathematicaLicScript run hourly by typing

crontab -e

and adding these two lines to the bottom:

42 * * * * /[exePath]/MatlabLicScript
42 * * * * /[exePath]/MathematicaLicScript

This causes the scripts to run every hour (on the 42nd minute).

• (optional) replace "[dataPath]" in lic-usage.php with the correct path.
