## What it is
Vector is an on-host performance monitoring web application that exposes high-resolution system and application metrics (backed by PCP) in an engineer's browser. Netflix has retired it as a standalone app, contributing its capabilities to the PCP/Grafana ecosystem.

## Use cases
- monitor high-resolution host performance metrics in a browser
- troubleshoot system performance issues on-demand
- visualize PCP metrics with custom dashboards
- inspect flame graphs for performance analysis
- self-host a performance monitoring UI

## When to choose
- you already run PCP and want a lightweight browser-based metrics UI
- you need a legacy self-hosted alternative to Grafana for PCP data

## When to avoid
- starting a new monitoring stack - the project is retired in favor of PCP + Grafana
- you need active support or updates - issues are best-effort only
- you want Netflix-specific flame graph features, which moved to internal tooling

## Facets
- artifact type: application
- maturity: abandoned
- function: monitoring, data-visualization, analytics
- domain: monitoring, performance, developer-tools
- platform: self-hosted
- tags: pcp, grafana, flame-graphs, performance-monitoring, react, retired-project, devops, web-server, javascript, linux
