Welcome back to our six-week journey to prepare for your Site Reliability Engineering (SRE) interview! By now, you've covered the fundamentals of SRE in Week 1 and grasped automation and scripting in Week 2. If you've been following along, you're well on your way to covering all the essential skills required for a successful SRE career.
This week, we're taking another significant step forward as we get into the critical stack of monitoring and alerting. Now, it's time to equip yourself with the knowledge and tools needed to keep an eye on systems, analyze performance, and respond quickly to any issues that may come up.
Monitoring and alerting are at the core of Site Reliability Engineering. They enable you to maintain the reliability and availability of complex systems, and Week 3 is all about cracking these concepts. Throughout this week, we'll explore the key elements of monitoring, logging, and alerting, and we'll introduce you to powerful tools like Prometheus and Grafana.

Days 1-3: Monitoring, Logging, and Alerting
Monitoring, logging, and alerting are the backbone of Site Reliability Engineering (SRE) because they provide real-time visibility into system performance, identify potential issues, and enable quick response to incidents. Monitoring helps track system health and performance metrics, while logging captures essential data for troubleshooting and forensic analysis. Alerts act as early warning systems, ensuring that problems are addressed proactively, minimizing downtime, and enhancing the overall reliability of digital services.
