Cloud Monitoring and Logging

1. Introduction

Cloud Monitoring and Logging are critical components of cloud infrastructure management. They provide insight into application performance, resource utilization, and overall system health.

2. Key Concepts

• Monitoring: The continuous observation of system metrics to ensure optimal performance.
• Logging: The process of recording events, errors, and system messages for analysis and troubleshooting.
• Alerts: Notifications based on predefined thresholds or events that indicate potential issues.

3. Cloud Monitoring

Cloud monitoring encompasses a range of tools and services designed to track system performance, availability, and resource usage.

aws cloudwatch put-metric-alarm --alarm-name "High CPU Alarm" --metric-name "CPUUtilization" --namespace "AWS/EC2" --statistic "Average" --period 300 --threshold 70 --comparison-operator "GreaterThanThreshold" --evaluation-periods 1 --alarm-actions "arn:aws:sns:us-east-1:123456789012:MyTopic"

4. Cloud Logging

Cloud logging allows you to capture application and system logs to troubleshoot issues and analyze system behavior.

import logging
from google.cloud import logging as gcloud_logging

client = gcloud_logging.Client()
client.setup_logging()

logging.info("This is an informational message")
logging.error("This is an error message")

5. Best Practices

• Use structured logging for easier analysis.
• Set up alerts for critical metrics and log events.
• Regularly review logs and monitoring data to identify trends.
• Implement a centralized logging solution for better visibility.
