Profiling Java @ 2019

A good profiler can really help you in your work while coding Java (I assume while coding any coding language but I am referring to Java here)

It can find memory leaks (Which object and how many of it takes the most of your limited memory?), CPU bottlenecks and other surprising data like the time consumed by each network call / DB query etc.

Thus it is not so surprising to find many different java profilers around.

I will try to map here the Java profiling tools lying around
My short list of requirements will include the following:

Profiler Requirements


  • Constantly updated profiler (how a profiler built to profile Java6 will behave with Java11?)
  • Clear GUI - As I will want to dive into the profiling data - it will be much simpler using UI
  • Free (With a big advantage to the open sourced ones)
  • (Optional) Remote profiling

List of Profilers

Dead Profilers (At least 5 years without an update)


Non Free Profilers

Not Good Enough (for me)

  • JvmTop - 2015, Only CPU profiler and has no GUI
  • Netbeans Profiler - Bundled with netbeans (Which I don't use)

Profilers Worth Checking


Summary

In this post I have listed many java profilers.
The non-relevant ones are important to map as well as those ones which are worth checking as it is important to iliminate those you won't use in order to shorten the path to finding the right tool for your trade.

Ant Explorer graphical Ant build tool

Every serious java developer needs to create or edit some ant building script. Eclipse offers nice ant handling features which make the task much easier, eclipse's plugin (which is embeded into eclipse since version 3.1 or so) understands the ant scripting language thus enables not only syntax coloring but also nice mouse hovering which reveals values of properties, variable names which enables finding the source of each variable and also some nice debugging features. But, there is one field in which eclipse's ant handling lacks perfection, its in viewing the whole build file in one gaze graphically feature, that feature isn't supported by eclipse. Luckily enough, it is supported by YWorks, which created a nice and free util which loads an ant script file and shows it in a beautiful and so very useful way. I think that this util (which was released as a standalone as well as an eclipse and idea) is a must for any serious java developer. Unluckily, YWorks have remo

Start Working with AutoIT

I have decided I needed a quick GUI creator which can create a small exe file displaying the GUI, with no system dependencies like a .NET framework or Java runtime. What options do I have for a Quick GUI Creator? Maybe there are many options I am not aware of, but after extensive searching I found these two: Auto Hot keys AutoIT (Saw some recommendations to try Delphi or Pascal for this task but I passed) Both tools began from the same code source, autohotkeys branched off and continued to be open source while AutoIT is more commercial. I have compared the two (well, not actually compared, just google'd out other's comparisons) and found out that the AutoHotKeys is slightly better and is more open sourced (which makes it the better solution) but lacks in one field which is crucial for me - the script syntax is awful!  That tipped the balance (as a programmer i couldn't stand AHK's syntax) so I chose AutoIT. How to get Started with AutoI
