first create an app with the test_server:
sudo pmon2 run bin/test_server --args "-h 10.132.204.203 -p 5556 -r 5001" --user terraform
now issue the same command again but with a different port argument
sudo pmon2 run bin/test_server --args "-h 10.132.204.203 -p 5555 -r 5000" --user terraform
We'll get:
FATA process already running with the name provided: test_server
Now we specify the name parameter.
sudo pmon2 run bin/test_server --args "-h 10.132.204.203 -p 5555 -r 5000" --user terraform --name server-replica
Now ps
shows two separate process with but pmon2 only shows 1!

It's because the previous developers are erroneously using process.process_file as a primary key in the persistence layer. https://github.com/joe-at-startupmedia/pmon2/blob/7ba346e93cc72d53a6cb5454db86dc5d78e6ff80/cli/service/add.go#L13
Terminating all process and restarting pmond results in 3 process records all sharing the same pid:
