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)
