How to Calculate SLO Error Budget in Python
Simulate an SLO error budget by computing allowed downtime from a target availability percentage and mocking monthly incidents.
```python
import random
def calculate_error_budget(total_seconds: int, target_availability: float) -> float:
return (1.0 - target_availability) * total_seconds
def simulate_monthly_availability(seconds_in_month: int, budget_seconds: float) -> float:
# Mock: randomly consume a fraction of the error budget i…How to Implement an Error Budget Policy in Python
This code implements a mock error budget policy that decides whether to freeze deployments based on a simulated error rate and monthly freeze limits.
from datetime import datetime, timedelta
class ErrorBudgetPolicy:
FREEZE_WINDOW_HOURS = 24
MAX_FREEZES_PER_MONTH = 3
def __init__(self, budget_percentage=99.9):
self.budget_percentage = budget_percentage
self.freeze_count = 0
self.last_freeze_start = None
