Hi,

The unique names for each Node in a cluster is great when looking at  
logs but when it comes to identifying each node in a cluster when  
looking at its process using "ps -ef" in unix envs, then all the nodes  
in the cluster look the same. Is there an admin command or some other  
way that people have found for finding the process id of each node.

Best Regards,

David.

You get the process id as part of the nodes info API. If you want to get the info just for the node you hit, then using \_local. For example:

curl localhost:9200/\_cluster/nodes/\_local?pretty=1
