Tune Java GC settings in seconds

Powerful tool to tune your application's memory and GC settings. Key performance Indicators and GC statistics section of the report, helps you to tune to perfection.

Amazing memory visualizer

Vision starts from visualization. Industry expert's vision of Java memory modeling is visualized in GCeasy log analysis reports.

GC Log Analysis REST API

In this modern world, Garbage collection logs are still analyzed in a tedious & manual mode. i.e. you have to get hold of Operations engineer, then he will mail you the application's GC logs, then you will upload the logs to GC analysis tool, then you have to apply your intelligence to anlayze it.

There is no programmatic way to analyze Garbage Collection logs in a proactive manner. Given this tediousness, it's impossible to analyze hundreds of JVM's GC logs in one stroke. Thus to eliminate this hassle, we have developed RESTful API to analyze garbage collection logs. With one line of code you can get your all your GC logs analyzed instantly. Learn how to use GCeasy REST API

REST API for java GC analysis
One tool to parse all GC formats

Universal Java GC Viewer

Based on the GC algorithm, Java version, JVM provider and memory arguments that you pass, GC log format will vary. GCeasy is the industry's first online GC log analyzer which can analyze GC logs of any format.

  • Serial GC, Parallel GC, CMS GC, G1 GC, Z GC, Shenandoah GC, Zing GC, Jstat
  • Java version: 1.2, 1.3, 1.4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, 17, 18, 19, 20, 21, 22
  • JVM Provider: Oracle, IBM, HP, Azul, OpenJDK
  • Android GC logs: Dalvik GC Log, Android Runtime (ART) GC Log
  • Supports Unified GC logging format
  • All types memory settings
  • Full Support

Thus we are proud to be called as Universal JVM Garbage collection log analysis tool

How it works?

Java GC Tuning is made to appear as rocket science, but it's a common sense!

  • 1

    Enable GC Logs

    You can enable GC log by passing following JVM arguments:
    Until Java 8: -XX:+PrintGCDetails -Xloggc:<GC-log-file-path>
    Java 9 & above: -Xlog:gc*:file=<gc-log-file-path>

  • 2

    Upload GC logs to GCeasy

    Upload the generated GC logs to GCeasy and see the world-class GC reports instantly.

  • 3

    You can also use REST API

    To analyze hundreds of JVMs GC logs in a proactive manner, you can use our REST API

FAQ

Frequently Asked Questions. If you have further questions mail us: support@tier1app.com

How to enable Java GC Logging?

For Java 1.4, 5, 6, 7, 8 pass this JVM argument to your application: -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:<file-path>

For Java 9, pass the JVM argument: -Xlog:gc*:file=<file-path>
file-path: is the location where GC log file will be written

GCeasy couldn't parse my GC Logs?

We do support all of the GC log formats irrespective of the JVM version, JVM provider, GC algorithms, memory settings.

However if we don't support your format, Please report it to support@tier1app.com. We will fix it.

Can I install this tool locally?

Yes, you can install this tool locally, so that you don't have to upload the GC logs to our servers. Please see the pricing for this plan.
