Infrastructure Monitoring
Infrastructure Monitoring is like having a health-tracking system for a company's computer systems and networks. Just as doctors monitor vital signs in patients, Infrastructure Monitoring tools watch over servers, networks, and applications to make sure everything is running smoothly. These tools alert IT teams when something goes wrong, like when a website becomes slow or when storage space is running low. Popular monitoring systems include Nagios, Zabbix, and New Relic. This helps companies prevent problems before they affect customers and keeps digital services reliable.

Senior Level Questions
Q: How would you design a monitoring strategy for a large-scale infrastructure?
Expected Answer: A strong answer should cover setting up monitoring across different layers (hardware, network, applications), establishing proper alert thresholds, and creating escalation procedures. They should mention the importance of reducing alert fatigue and prioritizing critical systems.
Q: How do you handle monitoring in a cloud environment versus on-premise systems?
Expected Answer: The candidate should discuss the differences between monitoring cloud services and traditional infrastructure, including using cloud-native monitoring tools, dealing with dynamic resources, and adapting monitoring strategies for scalable systems.
Mid Level Questions
Q: What's the difference between monitoring and alerting?

Q: How do you determine what metrics are important to monitor?
Expected Answer: The answer should cover identifying critical business services, understanding system dependencies, and selecting metrics that indicate system health and performance, such as response times, error rates, and resource usage.
Junior Level Questions
Q: What are the basic components that should be monitored in any system?
Expected Answer: They should mention basic elements like CPU usage, memory usage, disk space, network connectivity, and basic application health checks. Understanding of why these are important is key.
Q: What is the purpose of monitoring thresholds?
Expected Answer: Should explain that thresholds are pre-set limits that trigger alerts when exceeded, helping teams identify potential problems before they become critical issues.
