Tracing Policy
This reference documentation is generated from the Tracing Policy CRD specification, detailing its fields and usage.
A TracingPolicy is a user-configurable Kubernetes custom resource (CR) that defines how Tetragon observes events in both the kernel and userspace using eBPF. It supports a variety of hook points including kprobes, uprobes, tracepoints, LSM hooks, and USDTs, giving users fine-grained control over what to trace and what actions to take. Policies consist of hook points, selectors for in-kernel filtering, and optional actions that can be executed when a match occurs.
Tracing policies can be loaded and unloaded dynamically at runtime or applied at startup using configuration flags. Although structured as Kubernetes CRs, they can also be used in non-Kubernetes environments via Tetragon’s CLI or daemon flags. In Kubernetes, policies can be managed using kubectl or tools like Argo CD.
