Scouter is an open-source Application Performance Management (APM) tool similar to New Relic or AppDynamics, using a Java agent to instrument web applications and a host agent for OS metrics. It collects user, service, and resource metrics and visualizes them via dashboards, XLog scatter charts, and alert plugins.
Use cases
- monitor tomcat application performance
- open source alternative to new relic
- track response time and TPS of java services
- profile sql and method calls in production
- monitor server cpu memory and heap usage
- visualize distributed traces in a scatter chart
- set up custom performance alerts
When to choose
- you run Java web applications on Tomcat, JBoss, or Resin and need APM without licensing costs
- you want self-hosted monitoring with Telegraf integration for Redis, nginx, Kafka, MySQL, and more
- you need Zipkin-compatible tracing data shown in scatter charts
When to avoid
- your stack is primarily non-JVM and you don't use Telegraf or Zipkin instrumentation
- you prefer a fully managed SaaS APM with minimal setup
- you need first-class support for modern runtimes like Node.js, Python, or .NET agents
