Support official JFR APIs

Open crakjie opened this issue 6 years ago • 8 comments

With java 9 jrockit jars changed name. This making incompatibility with jfr-flame-graph

Hi @crakjie, Thanks for creating an issue on this. I will check on this.

Sort of relatedly, Java 10 now has an official API for consuming flight recording profiles

AFAIK the official api cannot read JFR files generated with previous versions of Java. JMC core jars have been open sourced and will be on maven central soon. With that you will be able to read any JFR recording from 7 to the latest JDK.

Hi @leogomes. Are you planning to support Java 11 or aware of any project doing so? If not I might create a jfr-flame-graph for Java 11 based on OpenJDK API.

Hi @cykl, I have plans to support latest official APIs

Noting that the backport of Flight Recorder to OpenJDK8u262 uses the new format and also isn't supported by jfr-flamegraph.

@retronym Thank you for informing. I was a bit away from Java for several months. I'm hoping to work on supporting official APIs soon.

Submitted a PR for this https://github.com/chrishantha/jfr-flame-graph/pull/24. It worked for my use case...
