Glowroot is an open-source, very low overhead Java APM (application performance monitoring) tool that installs as a JVM agent. It captures traces, SQL and service call data, response time charts, continuous profiling, and offers optional central collection with a web UI.
Use cases
- monitor java application performance in production
- find root cause of slow requests and errors
- capture and aggregate SQL query performance
- profile jvm applications continuously
- set up alerting on response time regressions
- self-hosted apm for tomcat or spring apps
- trace async requests across threads
When to choose
- you need a free, self-hosted APM for Java/JVM applications
- you want minimal overhead instrumentation via a single javaagent flag
- you need SQL, HTTP, and framework-level tracing out of the box
- you want quick setup with a built-in web UI
When to avoid
- your stack is not on the JVM
- you need APM for polyglot microservices beyond Java
- you require a managed SaaS observability platform
- you need deep frontend/browser performance monitoring
