Hello,

Is there documentation for which JFR events are emitted by the JVM, what
those events mean, and what fields those events have?

The closest I could find to a list of events was the profiling
configuration,

https://github.com/AdoptOpenJDK/openjdk-jdk/blob/master/src/jdk.jfr/share/conf/jfr/profile.jfc

But I don't see any documentation for what data is in those events, or what
those events mean.

For example, jdk.DataLoss looked like an interesting event, but googling
for it doesn't reveal anything.

Thanks,

Sean
