## What it is
Stagemonitor is an open-source application performance monitoring agent for Java server applications that integrates with Elasticsearch, Graphite, and InfluxDB, with preconfigured Grafana and Kibana dashboards. It supports OpenTracing and includes an in-browser widget, but the project is no longer maintained.

## Use cases
- monitor java application performance
- trace requests in a java servlet app
- profile jvm applications and collect metrics
- visualize apm metrics in grafana dashboards
- analyze request call stacks with kibana
- self-hosted apm for java servers

## When to choose
- you need a self-hosted, open-source APM agent for a legacy Java stack
- you already run Elasticsearch, Grafana, or Kibana and want integrated dashboards
- you need OpenTracing support in a Java servlet application

## When to avoid
- starting a new project - the project is explicitly unmaintained
- you want active support or modern OpenTelemetry-based instrumentation
- you prefer a SaaS APM with ongoing updates

## Facets
- artifact type: library
- maturity: abandoned
- function: monitoring, tracing, benchmarking
- domain: monitoring, performance, backend
- platform: jvm, self-hosted
- tags: apm, opentracing, elasticsearch, grafana, kibana, java-agent, unmaintained, devops
