The following program helps you to monitor the status of a raspberry pi. The common parameters that we monitor are CPU, Memory & Disk. This program can be used to get the info of any operating system. This is not limited to raspberry pi.
Here I am providing a simple program that provides the details of all these three parameters. You can enhance this program further and make it part of your application.
| import psutil | |
| # Get cpu statistics | |
| cpu = str(psutil.cpu_percent()) + '%' | |
| # Calculate memory information | |
| memory = psutil.virtual_memory() | |
| # Convert Bytes to MB (Bytes -> KB -> MB) | |
| available = round(memory.available/1024.0/1024.0,1) | |
| total = round(memory.total/1024.0/1024.0,1) | |
| mem_info = str(available) + 'MB free / ' + str(total) + 'MB total ( ' + str(memory.percent) + '% )' | |
| # Calculate disk information | |
| disk = psutil.disk_usage('/') | |
| # Convert Bytes to GB (Bytes -> KB -> MB -> GB) | |
| free = round(disk.free/1024.0/1024.0/1024.0,1) | |
| total = round(disk.total/1024.0/1024.0/1024.0,1) | |
| disk_info = str(free) + 'GB free / ' + str(total) + 'GB total ( ' + str(disk.percent) + '% )' | |
| print("CPU Info–> ", cpu) | |
| print("Memory Info–>", mem_info) | |
| print("Disk Info–>", disk_info) |
