openjdk15 的 GCLogFileSize 热点标志替代

Question

I have issues with openjdk-15 for linux. So, my app run with next setup

-XX:+CrashOnOutOfMemoryError
-XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=tmp
-Xlog:gc:tmp/mygc.log

And I want to add limitations for GC logs via -XX:GCLogFileSize , but this HotSpot flag is not able for openjdk-15. Mb you know some alternative flags?

I've checked all available flags for my machine via PrintFlagsFinal , but don't find any relevant.

Most logging related flags were replaced with Unified JVM Logging .

Use -Xlog with filesize output option, eg

java -Xlog:gc:file=gc.txt:uptimemillis:filecount=5,filesize=1M
