About SigNoz
SigNoz is an open source, OpenTelemetry native observability platform for cloud native applications.

About metrics
Metrics is an infographics generator for GitHub accounts, published under the MIT license and written in JavaScript. It lives in the GitHub ecosystem as a GitHub Action and as a hosted web service, and it produces statistics about a user, an organization, or a repository. The output is rendered as SVG, Markdown, PDF, or JSON, which means the same generated figures can be embedded in a profile readme, attached to a blog post, or consumed by another tool.
