What methods and tools are used to ensure observability of network traffic and processes in Kubernetes?

The following methods and tools are used for observability of network traffic and processes in Kubernetes:

• Logging: Collecting logs using Fluentd, Logstash, or built-in Kubernetes solutions (kubectl logs).
• Monitoring: Prometheus for metrics collection, Grafana for visualization.
• Tracing: Tools like Jaeger or Zipkin for distributed request tracing.
• Network Monitoring: Using CNI plugins with monitoring support (e.g., Calico), as well as tools like Weave Scope or Cilium for visualization and analysis of network traffic.
• Kubernetes Events: Tracking cluster events via kubectl or API.

These tools together provide a comprehensive view of the application's and network's state within the cluster.
