Pixie is an open-source observability platform for Kubernetes that uses eBPF to automatically capture telemetry data from clusters without requiring any manual instrumentation or code changes. It functions as an eBPF telemetry collector, a continuous application profiler, a network traffic analyzer, and a scriptable telemetry query engine, all within a single Kubernetes-native tool. The platform distinguishes itself through several integrated capabilities. It continuously samples stack traces from compiled-language code to identify CPU performance bottlenecks, visualizing the results as inter

Inspektor Gadget is an eBPF observability toolset and program framework designed for tracing Linux systems and debugging Kubernetes nodes. It provides a suite of tools to collect kernel-level telemetry and export system metrics via the OpenTelemetry standard. The project distinguishes itself by packaging inspection tools as OCI-compliant container images, allowing for standardized distribution and deployment across clusters and hosts. It employs a modular data processing pipeline that utilizes WebAssembly modules to transform and filter telemetry, and leverages Compile Once Run Everywhere for

This project is a command-line plugin for Kubernetes that provides direct root shell access to the underlying host operating system of a cluster node. It is designed to facilitate administrative tasks, system maintenance, and diagnostic operations on nodes, including those running immutable or container-optimized operating systems that lack native shell environments. The tool functions by dynamically scheduling ephemeral, privileged pods that share the host's process, network, and filesystem namespaces. By leveraging node affinity constraints, it ensures that these diagnostic sessions are exe
