## Description:

[Detailed description of the issue or question]

In PMM, node and service don’t give each other an option to identify, how do they connect to each other?

If there is one node and one service in one server, they identify each other well, but if there are two nodes and two services in one server, I don’t know how to connect each node and service.

## Steps to Reproduce:

Hi @pmmChobo,

You can identify individual service by assigning them unique name while adding them.  
I see you have noted the command that has --service-name flag.  
I believe on the same line you can add the node names probably two containers on a server?
