## What it is
A Java web application from Yahoo for MySQL performance monitoring and analysis, packaged as a Jetty-wrapped WAR with a built-in Derby or MySQL metrics store. It collects and visualizes MySQL performance metrics through a browser UI.

## Use cases
- monitor mysql query performance over time
- analyze mysql server health metrics
- set up a self-hosted mysql monitoring dashboard
- track mysql performance counters and store metrics history
- diagnose slow mysql database performance
- collect mysql metrics without installing agents

## When to choose
- you need a lightweight, self-hosted MySQL performance monitor
- you want a Java-based tool deployable as a WAR on existing infrastructure
- you prefer a simple web UI over configuring heavier stacks like Prometheus plus Grafana

## When to avoid
- you monitor databases other than MySQL
- you need modern alerting, clustering, or active community maintenance
- you want a cloud-native or container-first monitoring solution

## Facets
- artifact type: application
- maturity: maintenance
- function: monitoring, analytics, data-visualization
- domain: databases, monitoring, performance
- platform: jvm, self-hosted, windows
- tags: mysql, database-monitoring, performance-analysis, jetty, metrics-collection, devops, web-server, linux, macos
