Hi team, The `jcmd` command can be used to call some built-in diagnostic commands in vm. Can we consider extending it to the java layer like perf data, so that Java developers can customize their diagnostic commands and then call them through `jcmd`?
One application scenario I can think of for this extension is that some statistical information may be collected in a java application. Triggering the output of this statistical information through the `jcmd` command seems to me relative to other mechanisms that trigger output (such as through an HTTP service, or periodic Printing) is more convenient. Any input is appreciated. Thanks, Denghui Dong
