You have access to the following command line arguments (Flags) that the program accepts:

• "--ucpu" (Displays CPU Utilization Graph in %)
• "--umem" (Displays Memory Usage Graph in GB)
• "--ucores" (Returns Number of CPU Cores along with Max CPU Frequency)
• "--nsam=N" (If used the value N will indicate how many statistics are collected)
• "--ninterval=T" (If used the value T will indicate how frequently to collect satatistics)

It should be noted that the DEFAULT value of samples = 20 and tdelay = 500000 microseconds

It should also be noted that by DEFAULT all statistics are displayed (Memory, CPU, Cores). If a command line argument is passed to display a specific statistic, then the program defaults to only displaying that specific statistic

Number of samples and tdelay are also accepted in the format: "./myMonitoringTool [N [T]]"

Take as example:./myMonitoringTool 50 600000 --ucpu --ninterval=100

Note that "50" is read as the number of samples, "600000" is read as tdelay in microseconds, and the extra "--ninterval=100" command is ignored.

We also observe the "--ucpu" command, this indicates that the program will now only display the CPU graph.

• Compile the code, use the following command in a UNIX terminal:

gcc system_monitory_tool_shaaf.c --std=c99 -o myMonitoringTool

• Run the Program, use the following command in a UNIX terminal: (This runs the program using its DEFAULT settings)

./myMonitoringTool

• You can use multiple command line arguments to change how the program runs:

./myMonitoringTool  [nsam [ninterval]] [--umem] [--ucpu] [--ucores] [--nsam=N] [--ninterval=T]

More information about: Commands Breakdown

This program is written in C language and it displays UNIX system information in real time using graphs. With this program, you can view the following system information:

• Memory Usage (in GB)
• CPU Utilization (in %)
• Number of CPU cores and max CPU frequency (in GHz)

This program reads data from the following UNIX files:

• /proc/meminfo
• /proc/stat
• /proc/cpuinfo
• /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

The graphs in the terminal are all updated using ANSI escape sequences. You need to have a terminal that supports ANSI escape sequences, and access to a UNIX system, and GCC (or any alternative C compiler).

This README file is intended to give a High-Level Overview of my system_monitory tool, how to compile it, and how its various options allows the user to monitor system statistics.
