Where can I find the ports of all running pm2 apps?

node.js pm2

I have a server with PM2 installed and 10 running node apps. Every App should run with a different port number. When I install a new App on the server I need the information about the used ports. With 'pm2 list' I get much info about the apps but not the port.

pm2 list

App name       │ id │ version │ mode │ pid   │ status │ restart │ uptime │ cpu  │ mem        │ user │ watching
example_name   │ 1  │ 0.0.0   │ fork │ 25651 │ online │ 0       │ 37D    │ 0%   │ 386.3 MB   │ root │ disabled

I can not find a overview of all used ports and I can't believe that this important information is not given by PM2. Does anyone have any idea where I see a list with all used ports in PM2?

Yeah this is a bit of a failing with pm2 IMHO. Only when you have more than one instance (site) running on the server. I use:

ss -tnlp | grep "node /"

You can then eyeball the pid from pm2 and the port, or in my case you get just a snippet of the directory it's running from. UPDATE: you can use this monstrosity:

ss -ntlp | grep $(pm2 ls | grep "SITENAME" | awk '{print $10}') | awk '{print $4}'

Which dumps the port out.

The OP added a comment saying he added the port number into the name of the running node app, which could get messy, but is a good idea.
