Glowroot

Open source Java APM


(Very) easy to use

Download and unzip glowroot-0.12.3-dist.zip, add -javaagent:path/to/glowroot.jar to your application's JVM args, point your browser to http://localhost:4000, and see all this!

Very (very) low overhead

Overhead depends on many factors, but is generally in the low microseconds due to extensive microbenchmarking and tuning of Glowroot itself.
