What is DedicatedWorker and pool?

How can I see their thread and source in bash for instance if I want to know where pool is getting initiated and on which port it is running?

Htop process

As shown in the image, I am interested to know about the origin of the pool command in the htop table, if that's possible.

    Press "t" when running htop to see the processes listed as a tree. Then visually follow the tree upward and you'll see the path to the executable which initiated pool. – Emmanuel Rosa Dec 10 '18 at 7:40

    Then try p to see the process's command path. – muru Dec 10 '18 at 8:43

pres t or F5 followed by pressing p in htop, and origin will be seen. As here 'pool' is spawned from

light-dm -> unity -> /sbin/upstart --user
