Apache SkyWalking

Apache SkyWalking is an open source APM system for microservices, cloud-native, and container-based architectures. It collects monitoring, tracing, and diagnostic data from distributed systems and brings service topology, service-centric observability, and dashboards together in one place.

It covers distributed tracing, metrics, logs, profiling, and alarms, with agents for Java, .NET Core, PHP, NodeJS, Go, Lua, Rust, C++, browser JavaScript, and Python. eBPF-based monitoring and profiling arrive through Rover for Kubernetes, and it ingests telemetry from Zipkin, OpenTelemetry, Prometheus, Zabbix, and Fluentd.

Apache SkyWalking is governed by the Apache Software Foundation under the Apache License 2.0. It stores observability data in BanyanDB, its purpose-built native database, and is self-hosted.
