About:
Tetra is the official command-line interface for Tetragon, a Kubernetes-observability and security runtime. It enables users to interact with Tetragon's eBPF-based event stream, allowing for real-time monitoring of process executions, file accesses, and network activity. The tool is essential for debugging security policies and inspecting system behavior directly from the terminal.
Key Features:
  • Live event observation from eBPF probes
  • Execution and process tracing
  • Policy management and debugging
  • JSON output for scripting integration
Use Cases:
  • Troubleshooting security policy violations in real-time
  • Forensic analysis of process execution chains on a node
  • Debugging Tetragon agent connectivity and performance
Alternatives:
  • kubectl – Generic Kubernetes interface; lacks specific awareness of eBPF events without plugins.
  • bpftool – Low-level eBPF inspection utility; requires deep kernel knowledge compared to Tetra's high-level abstraction.
