Hi, I have a question about Meltano UI, each of (tap)task will be run in different container/machine, is there a way to collect all the information from all the tasks including the data in order to view the pipelines in one place and create dashboards.

Each time you run

meltano elt

or run it from the UI, a tap AND a target are both run. If your target is configured to point to the same database, then all your data will be available in that database. From there, you can do further processing like joining data together and creating a dashboard using the combined data

you mean that all the data and metadata is saved to the database I configured, e.g. postgres, therefor, I will be able to open the meltano UI on some other machine that configured to use the same database, I will see all the pipelines, jobs, and exploring the data?

That's the idea of meltano, yes

Yep, exactly!
