why no such flag 'loggc' using jinfo
I want to know -Xloggc value for a given Java process with command
jinfo -flag loggc 12345，
but it prints: no such flag 'loggc'.
The explanation(https://docs.oracle.com/javase/7/docs/technotes/tools/share/jinfo.html) of command 'jinfo -flag name' is:
prints the name and value of the given command line flag.
so, is -Xloggc not command line flag?

This is a dump of all the flagsjava -XX:+PrintFlagsFinal -versionYou might need to dump the command line args instead.

The explanation at https://docs.oracle.com/javase/7/docs/technotes/tools/share/jinfo.html is not quite accurate. In recent JDK (i.e. JDK 8u191 and JDK 11.0.1) it has been changed to
-flag <name> to print the value of the named VM flag
-Xloggc is not a named JVM flag, but rather a command-line argument that is translated to multiple JVM flags, in particular, -XX:+PrintGC and -XX:+PrintGCTimeStamps.
To get the VM command line, run
jcmd 12345 VM.command_line
To see the full list of JVM flags, run
jcmd 12345 VM.flags -all
