Kelemetry is a tracking system for the Kubernetes control plane developed by ByteDance. It connects the behavior of multiple Kubernetes components from a global perspective, and tracks the complete life cycle of a single Kubernetes object and the interaction between different objects. By visualizing the event chain in the K8s system, it makes the Kubernetes system easier to observe, understand, and debug.

characteristic:

• Collect audit logs
• Collect controller events (i.e. the “events” section in kubectl describe )
• Records object differences associated with the audit log
• Link objects by owner reference
• Collect data from custom sources (Plugin API)
• Connect objects with custom rules via multi-cluster support (plugin API)
• Navigate the track using the Jaeger UI and API
• Scalable to multiple large clusters
• Build custom metrics from audit logs
