DevOps Monitoring & Logging Explained
Essential Guide for DevOps Engineers
Why is monitoring important in DevOps?
Monitoring helps detect:
- Application failures - Catch errors before users report them
- Performance issues - Identify slow responses and bottlenecks
- Infrastructure outages - Get alerts when servers go down
Without monitoring, you're flying blind. Monitoring provides real-time visibility into system health and helps maintain high availability.
What tools are used for monitoring?
Common tools:
- Prometheus - Open-source metrics collection and alerting
- Grafana - Beautiful dashboards and visualization
- CloudWatch - AWS native monitoring service
- ELK Stack - Elasticsearch, Logstash, Kibana for log analysis
What is logging in DevOps?
Logging captures application and system events for debugging and auditing. Logs record what happened, when it happened, and why it happened. They're essential for troubleshooting production issues, tracking user actions, and maintaining security compliance.
