Maintainer activity

4 people did triage or write work on this repository in the last 12 months.

Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 18, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits. How this is counted.

How this project is maintained

About 8% of issues opened in the past year have never received a reply. 70% of open issues come from outside the core team, so the backlog reflects real-world use rather than internal planning. Work labelled "bug" is answered fastest, typically in about 2 hours, while "plexus" waits about 7 weeks. Almost all tracked open issues have seen activity in the last three months. 79% of issues opened in the past year have been closed, leaving a working backlog.

Detailed Description

Jaeger UI is a web interface for visualizing and analyzing distributed traces collected by Jaeger.

The tool addresses the challenge of understanding system behavior across microservices by providing a visual interface to explore trace data. It allows developers to search for traces and examine detailed trace information, making it easier to identify performance bottlenecks and debug issues in distributed systems. The UI connects to Jaeger's backend to retrieve and display trace data in an interactive format.

Jaeger UI is suitable for teams running Jaeger as their distributed tracing solution who need a way to query and visualize traces through a browser. It works best in environments where developers and operators need to investigate system behavior across multiple services. The tool is part of the broader Jaeger ecosystem and serves as the primary interface for interacting with collected trace data. Configuration options allow customization of UI behavior, including Google Analytics integration and menu customizations, making it adaptable to different organizational needs.

The project maintains active development with regular updates to its TypeScript and React codebase. Contributions are welcomed through a documented process with clear guidelines for development setup and coding standards. The project provides resources for users to get help when encountering issues or bugs through established communication channels.
