JavaアプリケーションのMBeanの情報一覧を取得する

Scala 2.12

import java.lang.management.{ManagementFactory, PlatformManagedObject}

import javax.management.{MBeanInfo, ObjectName}

import scala.collection.JavaConverters._

val mbeanInterfaces: Seq[Class[_ <: PlatformManagedObject]] = ManagementFactory.getPlatformManagementInterfaces.asScala.toSeq
val mbeanObjects: Seq[_ <: PlatformManagedObject] = mbeanInterfaces.flatMap(ManagementFactory.getPlatformMXBeans(_).asScala.toSeq)
val mbeanObjectNames: Seq[ObjectName] = mbeanObjects.map(_.getObjectName)
val mbeanInfos: Seq[MBeanInfo] = mbeanObjectNames.map(ManagementFactory.getPlatformMBeanServer.getMBeanInfo(_))

MBeanInfoObjectNameをつかってMBeanServer(ManagementFactory.getPlatformMBeanServer)経由で情報を取得する。
