我如何找出运行erlang进程的哪个节点？ [英] How do I found out which node an erlang process is running on?

问题描述

鉴于我可以将PID从进程发送到另一个进程，即使在节点之间，如果我从不同进程（可能在不同的节点）处的进程接收到Pid，我如何知道哪个节点是有问题的PID运行在/ on？

erlang：process_info（Pid）似乎没有该信息。 / p>

谢谢。

解决方案

erlang：node / 1

节点（Arg） - > Node

返回Arg所在的节点。 Arg可以是pid，引用或端口。如果本地节点不存在，则返回nonode @ nohost。

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) does not seem to have that information in it.

Thanks.

解决方案

erlang:node/1

node(Arg) -> Node

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.
