Pixie Overview

Pixie is an open source observability tool for Kubernetes applications. Pixie uses eBPF to automatically capture telemetry data without the need for manual instrumentation.

Developers can use Pixie to view the high-level state of their cluster (service maps, cluster resources, application traffic) and also drill-down into more detailed views (pod state, flame graphs, individual full body application requests).

Pixie was contributed by New Relic, Inc. to the Cloud Native Computing Foundation as a sandbox project in June 2021.

Features

  • Auto-telemetry: Pixie uses eBPF to automatically collect telemetry data such as full-body requests, resource and network metrics, application profiles, and more.

  • In-cluster edge compute: Pixie collects, stores and queries all telemetry data locally in the cluster. Pixie uses less than 5% of cluster CPU, and in most cases less than 2%.

  • Scriptability: PxL, Pixie’s flexible Pythonic query language, can be used across Pixie’s UI, CLI, and client APIs. Pixie provides a set of community scripts for common use cases.

Architecture

Platform Architecture

The Pixie platform consists of multiple components:

  • Pixie Edge Module (PEM): Pixie's agent, installed per node. PEMs use eBPF to collect data, which is stored locally on the node.

  • Vizier: Pixie’s collector, installed per cluster. Responsible for query execution and managing PEMs.

  • Pixie Cloud: Used for user management, authentication, and proxying “passthrough” mode. Can be hosted or self-hosted.

  • Pixie CLI: Used to deploy Pixie. Can also be used to run queries and manage resources like API keys.

  • Pixie Client API: Used for programmatic access to Pixie (e.g. integrations, Slackbots, and custom user logic requiring Pixie data as an input)
