Is there a replacement for the garbage collection JVM args in Java 11?
List of your <arguments, current mapping, reasons>
is as follows:
-XX:+PrintGCTimeStamps
-XX:+PrintGCDateStamps ==> decoration options
-Xlog:::time,level,tags
-XX:+PrintGCDetails ==> -Xlog:gc*
-XX:+PrintGCApplicationStoppedTime ==> -Xlog:safepoint
Note: PrintGCApplicationConcurrentTime
and PrintGCApplicationStoppedTime
are logged on the same tag and not separated in the new logging.
-XX:+UseGCLogFileRotation
-XX:NumberOfGCLogFiles
-XX:GCLogFileSize ==> output options
-Xlog::::filecount=5,filesize=1024
The bits that are handled by the framework do require tweaking
Reference: The documentation I've referred to and request you to follow for such migration details.
It does print date with time
-Xlog:gc*:verbose_gc.log:time
[2019-05-13T14:01:03.356+0530] Heap region size: 1M
[2019-05-13T14:01:03.357+0530] Using G1
NOTE :- JDK 11 been used
BTW, although the NumberOfGCLogFiles
and GCLogFileSize
options are gone in Java 11, it is still possible to set rolling file size and count. For example:
java -Xlog:gc*,safepoint:gc.log:time,uptime:filecount=100,filesize=128K ...
