查看本地或远端JVM进程的虚拟机进程标识(操作系统的进程号),默认输出本地JVM进程标识,类名或jar文件名称,以及启动方法参数;
options常用参数:
-m 输出传递给main方法的参数
-l 输出应用main方法的完整包名或者jar文件的完整路径
-v 输出传递给虚拟机的参数
hostid常用参数:
protocol 通信协议,默认为rmi
hostname 主机名或ip地址,默认为本机
port 目标机器通信端口,默认协议为rmi,默认端口1099
输出内容格式:
lvmid [ [ classname | JARfilename | "Unknown"] [ arg* ] [ jvmarg* ] ]
如果要根据jps命令输出解析应用的信息,需要根据不同版本做更新,否则可能导致输出结果存在错误。
