IMAT5122 - Computer Systems and Networks - Linux System Change Logger Script - Assessment Answer

Assessment Answer:

learning outcomes :
1. Demonstrate a systematic understanding of knowledge and show a critical awareness of current problems in computer systems and networks.
2. Show originality in the application of knowledge as well as a systematic understanding of knowledge and comprehension of the underlying concepts and principles associated with computer systems and networks.
3. Critically evaluate current computer system and networking technologies and methodologies and develop critiques of them.

You are an IT support engineer and you have been asked to build a GNU/Linux bash script that monitors a computer system and user activity regularly and logs key information. You need to create a script “mySysMonitor.sh” that automatically and regularly writes to a log file “mySysMonitor.log”. The log file will need to contain time-stamped detailed information about significant changes to the following:
1.Current processes
2. Users currently logged in
3. Devices plugged in (e.g. USB)
4.Disk usage
a.Overall disk usage
b.The user’s home directory (/home/someuser…)
c.Other key directories
5.Network interfaces and their states
6.Any other relevant information…
The script will need to be written to extract only key details about the changes to the computer system such as listed above and add them to an ever-growing log file. Hence the log file should consist of easily readable key details only. For pass level you are expected to write a script that satisfies a) to e) listed above. For higher marks, you are expected to add relevant extra information (e.g. monitoring OS system file changes, monitoring installed applications, etc.) and relevant features, more easily readable output (e.g. HTML), configurable log levels (e.g. verbose, debug, standard and key-details only), etc.
