Rinse and repeat... - * - * The payload will be parsed as even entries being keys, odd entries being - * values. - * - * The standard JDP packet contains four entries: - * - * - `DISCOVERABLE_SESSION_UUID` -- Unique id of the instance; this id changes every time - * the discovery protocol starts and stops - * - * - `MAIN_CLASS` -- The value of the `sun.java.command` property - * - * - `JMX_SERVICE_URL` -- The URL to connect to the JMX agent - * - * - `INSTANCE_NAME` -- The user-provided name of the running instance - * - * The protocol sends packets to 224.0.23.178:7095 by default. - * - * The protocol uses system properties to control it's behaviour: - * - `com.sun.management.jdp.port` -- override default port - * - * - `com.sun.management.jdp.address` -- override default address - * - * - `com.sun.management.jmxremote.autodiscovery` -- whether we should start autodiscovery or - * not. Autodiscovery starts if and only if following conditions are met: (autodiscovery is - * true OR (autodiscovery is not set AND jdp.port is set)) - * - * - `com.sun.management.jdp.ttl` -- set ttl for broadcast packet, default is 1 - * - `com.sun.management.jdp.pause` -- set broadcast interval in seconds default is 5 - * - `com.sun.management.jdp.source_addr` -- an address of interface to use for broadcast - */ - -package sun.management.jdp;
