JEP-271: GC Logging using Unified Platform Logger (new Format in Java9)

[ecki]

Hello,

just wanted to alert interested parties that JEP-271 (Unified GC Logging) is currently discussed and implemented on the openjdk gc-dev mailing list. Here is for example a preview of the new format (it basically limits variation to different additional log lines and allows switching on/off certain categories by Tags):

The JEP page is not completely current: http://openjdk.java.net/jeps/271

Hi Bernd, Thank you for posting these links. I have heard of them, but not yet analysed the JEP closely nor started an implementation of a parser supporting these logs. Best regards, Jörg

Two years later and Oracle/OpenJDK 9 has been released, making this more relevant.

I've published UL Viewer for drawing Java heap and other charts for Java 9. You might refer UL Viewer implementation if GCViewer has plan to adapt to Java 9.
