Design a System to Monitor the Health of a Cluster — System Design Interview Practice
Design a monitoring system to track health, performance, and availability of distributed clusters. Work through the requirements, architecture trade-offs, and an interactive design review.
Requirements and concepts to consider

- Alert on threshold violationsRequirement
- Visualize cluster topologyRequirement
- Historical metrics and trendsRequirement
- Support thousands of nodesRequirement
- Auto-discovery of new nodesRequirement
