perfix

Pretty basic profiling tool for JVM's

Highlights:

Provides method and SQL statement execution times. (Somehow it gives me more info than Java Mission Control)
Meant for development time (after process stops, data is gone).
Minimalistic commandline interface (ssh).
Execution time is measured in nanoseconds, reported in milliseconds (this way the totals and averages are most precise, but also human readable).
No manual instrumentation necessary using loadtime bytecode manipulation (javassist).
No special jdbc configuration necessary (ie no wrapped jdbc driver).
The agent is also the server (unlike commercial tooling). This way there is no overhead in interprocess communication.
Minimal memory footprint (agent is >only< 2.5 mb, it's still java right?).
Overhead (in method execution time) not clear yet. I wouldn't use it in production.

Agent that instruments loaded classes: -javaagent:/perfix.jar
Include classes for instrumentation with -Dperfix.includes=com.project. ...etc (includes subpackages)
Ssh interface to report executed methods and sql query excutions:
* #invocations
* total execution time for the method in nanoseconds (this is also the sorting order)
* average time in nanoseconds per method (= total/#invocations)
The ssh server starts on port 2048 by default. Use -Dperfix.port=... to adjust.

This has only been tested on oracle java8 in spring-boot using tomcat web-container
