IT infrastructure monitoring is the process of continuously observing and managing the hardware, software, networks, and services that make up an organization's IT environment. It is important because it helps ensure system performance, identifies issues before they escalate, minimizes downtime, enhances security, and supports efficient resource management.

Key metrics to monitor on a server include:

1. CPU Usage
2. Memory Usage
3. Disk I/O
4. Network Traffic
5. Disk Space Utilization
6. System Load Average
7. Process Count
8. Error Rates
9. Temperature and Power Usage
10. Application Performance Metrics

Infrastructure as Code (IaC) is a practice that allows you to manage and provision IT infrastructure using code and automation tools. It impacts monitoring by enabling consistent and repeatable environments, making it easier to implement monitoring solutions, automate alerts, and ensure that monitoring configurations are version-controlled and easily reproducible across different environments.

To monitor a Kubernetes cluster, you can use tools like Prometheus for metrics collection, Grafana for visualization, and Kubernetes Dashboard for a user-friendly interface. Additionally, consider using tools like ELK Stack (Elasticsearch, Logstash, Kibana) for logging and alerting systems like Alertmanager to notify on issues.

Proactive monitoring involves actively checking systems and applications to identify and resolve potential issues before they affect performance, while reactive monitoring occurs after an issue has been detected, focusing on responding to and fixing problems as they arise.
