Frequently asked questions

Why GCeasy?

Just 3 reasons:
1. Universal
There are several different Garbage Collection log formats. Garbage collection log formats vary by JDK version, Operating System, GC algorithm used, and configured GC system properties. GCeasy is the industry's first universal Garbage Collection log tool, which has the capability to process most of these formats.

2. Simplicity
Everything that we do is centered on one theme - "Simplicity".
Tool Usage - you don't have to download, install, and fiddle with memory settings to run this tool. The tool is designed in such a way that it can be used in just one easy step.
Intuitive Graphs/Metrics - GCeasy depicts graphs and metrics in a certain way that can be easily understood by anyone. We strive to keep them intuitive. Anyone can figure out what's going on without reading any descriptions, how to use guide, and video clip narrations.

3. Intelligence
We have developed sophisticated pattern analysis algorithms, which detects the memory/GC problems experienced by your application. So, you don't have to analyze the GC logs that are already done for your algorithms. Few pattern analysis algorithms are under production. When they are complete, the tool can forecast the potential GC/memory problems that your application may experience. GCeasy recommend solutions for several types of memory problems.

What graphs does publish?

Here goes few of the graphs that publishes:

Does the tool detect performance problems?

Yes. By applying sophisticated patterns on the GC logs, it uncovers memory problems in your application. Tool can detect whether your application is suffering from memory leaks, whether it might suffer from memory leak in near future, whether it's experience long GC pauses,.... Below is the screen shot of the problem reported by the tool:

Is this a free tool?

Yes, 'Public' version is free. On the other hand if you want private deployment, so that tool can run with in your corporate network, you can purchase our 'Enterprise' version. For more details check out our pricing

Great, the tool is free. But can you clarify the licensing when it comes to reusing the reports and their graphics? Is it ok to use them in a blog post? Or a company report?

Yes, you are welcome to use the graphics and other metrics provided by the GCEasy tool in your blog post or company report by specifying accreditation "Generated by" at the bottom of the graphics.

I am seeing great graphs and details, but still I am not able to solve memory problem. What should I do?

You can always reach us for help: We guarantee to get to root cause of any scalability, performance, availability problems with in 24 hours. We have solved hundreds of performance problems over the years. We are only engineers. There is no sales, no marketing, no overhead, so we are highly cost effective.

How to generate GC Log file?

Pass following JVM arguments: -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:<file-path> where file-path: location where garbage collection log should be saved.

Is GCEasy project open-sourced on Github?

No. Not yet. We are planning to do so in near future.

GCEasy isn't able to parse my GC Logs? What should I do?

Please report it to We will fix it.
