Here are production-tested, real-world DevOps automation examples in Python and Bash from reputable DevOps resources.

Python DevOps Automation Scripts

1. System Resource Monitoring

Monitor CPU and memory usage, sending alerts if thresholds are exceeded:

import psutil

def check_system_resources():
    cpu_usage = psutil.cpu_percent(interval=1)
    memory_usage = psutil.virtual_memory().percent
    if cpu_usage > 80:
        print(f"High CPU usage: {cpu_usage}%")
    if memory_usage > 80:
        print(f"High Memory usage: {memory_usage}%")

check_system_resources()

This type of monitoring is fundamental for production reliability.[1][2]
