プロジェクトの歴史

The Apache SkyWalking project announced SkyWalking CLI 0.1.0 on December 10, 2019. That first release added commands for listing services, instances, endpoints, and querying metrics, including an ASCII graph mode for linear metrics.

採用の歴史

The CLI grew as part of the wider SkyWalking observability distribution rather than as an independent general-purpose tool. Official documentation and examples use swctl in operational contexts such as health checks, debugging end-to-end tests, and checking reported Kubernetes events.

使われ方

swctl is commonly used by SkyWalking users and operations teams to query OAP through the same GraphQL protocol used by the UI. The official README documents installation through scripts, release binaries, source builds, and Homebrew on macOS.

パッケージ好きにとっての重要性

For package maintainers, swctl is a small but useful example of a project-specific operations CLI: it is packaged separately from the main server stack, has a stable executable name, and lets scripted deployments inspect observability state without bundling a full UI.

タイムライン

• 2019: Apache SkyWalking CLI 0.1.0 released.
• 2020: Multiple SkyWalking CLI releases followed as the SkyWalking 8 series matured.
• 2024: SkyWalking 10 release notes mention removal of the CLI from the image, reinforcing the CLI as a separately installed tool.
