将 Java 8 GC 日志重定向到 stderr

Question

Is there any way to print GC logs to stderr instead of stdout in SunJDK Java 8. I am using -verbose:gc to enable GC logs and it is redirecting to stdout by default. This can printed to a file using -Xloggc: argument.

But unable to print GC logs to stderr. Printing to stdout clutters my log file with GC allocation failure logs

Answer 1

For Java 8 use

java -Xloggc:stderr

For Java 9+ try using

java -Xlog:gc:stderr ...

Or for a higher log level

java -Xlog:gc=debug:stderr ...

Or for logging each garbage collection:

java -Xlog:gc*:stederr
