Hi @lokesh123

There is no official way to bind an exporter to a specific port.

You may use a workaround by limiting range of ports for pmm-agent. But it would work if only one service is monitored on a node.

Also it could a short delay for restarting pmm-agent

@Vadim_Yalovets Thanks.

It works.  
I set a limit for pmm-agent 40000 to 40002 as just want to MySQL instance and OS.
