如何确定Erlang进程(PID)在哪个节点上运行? [英] How do I found out which node an Erlang process (PID) is running on?

问题描述

鉴于我可以将一个进程的PID发送到另一个节点，甚至可以跨节点发送，如果我从另一个进程(可能在另一个节点上)中的一个进程收到一个PID，我怎么找出有问题的PID在哪个节点上在/上运行?

Given that I can send PIDs from a process to an other, even across nodes, if I receive a Pid from a process within a different process (possibly on a different node) how do I find out which node the PID in question runs in/on?

erlang:process_info(Pid)似乎没有该信息.

谢谢.

推荐答案

erlang:node/1

node(Arg)->节点

node(Arg) -> Node

返回Arg所在的节点.Arg可以是pid，引用或端口.如果本地节点不活跃，则返回nonode @ nohost.

Returns the node where Arg is located. Arg can be a pid, a reference, or a port. If the local node is not alive, nonode@nohost is returned.
