The System Activity Monitor is a utility that empowers you with real-time insights into your system's performance. It provides a comprehensive view of critical system statistics, enabling you to monitor resource utilization, identify bottlenecks.
- Real-time display of system statistics
- Refresh rate of 1-5 seconds
- Search functionality to filter output by application/process name (It will be added in the comming days)
- Overall CPU usage: The overall usage percentage of the CPU
- Overall CPU free: The percentage of CPU that is idle or free
- CPU usage per application/process: The usage percentage of CPU for each individual application/process
- Total memory: The total amount of system memory
- Free memory: The amount of free memory available
- Memory usage per application/process: The memory usage for each individual application/process
- Devices and partitions: The list of disk devices and partitions
- Read rate: The rate of data read from the disk (sectors/s)
- Write rate: The rate of data written to the disk (sectors/s)
The System Activity Monitor is implemented in C programming language and designed to run on Linux operating systems. Here are the key components and implementation details:
- Language: The monitor is written in C, leveraging its low-level system programming capabilities and portability across different Linux distributions.
- File Parsing: The monitor utilizes file parsing techniques to extract system information from various system files, such as /proc/stat and /proc/meminfo, to gather CPU, memory, and disk statistics.
- Real-Time Display: The monitor leverages terminal control sequences (ANSI escape codes) to achieve a real-time display of system statistics. It clears the terminal screen and updates the content periodically to provide up-to-date information.
- Process Identification: To obtain CPU and memory usage per application/process, the monitor reads information from the /proc/{PID}/stat and /proc/{PID}/status files, parsing the necessary fields to calculate and display usage statistics.
- Makefile: The provided Makefile automates the compilation process. It enables easy building of the system_monitor binary by running the
makecommand.
The System Activity Monitor provides the following information:
- CPU Usage: Displays the overall CPU usage percentage and usage per application/process.
- Memory Usage: Shows the total memory, free memory, and memory usage per application/process.
- Disk Activity: Lists the devices/partitions and their respective read and write rates.
- GCC (GNU Compiler Collection)
Follow these steps to build and run the System Activity Monitor:
- Clone the repository:
git clone https://github.com/anassajaanan/System-Activity-Monitor.git- Change into the cloned directory:
cd System-Activity-Monitor- Build the program using the provided Makefile:
make- Run the system_monitor program:
./system_monitor- The program will display the system stats in real-time with the specified refresh rate.
Feel free to customize the program based on your requirements. You can adjust the refresh rate, modify the output format, or extend the functionality to collect additional system statistics.
