Hello!

I think I understand a part of the custom daemon creation process, reading through other ZenPacks and documentation on libraries used has proven useful. However, I do have a few questions, and it would be great if someone could help me find answers for them.

Lets say I'm creating a custom Daemon, so I have 4 python files, each with the classes in brackets:

- Daemonconfig.py (DaemonDataSourceConfig, DaemonConfig)

- DaemonDataSource.py (DaemonDataSource, IDaemonDataSourceInfo, DaemonDataSourceInfo, DaemonDataSourcePlugin)

- config.conf.py

- zenDaemon.py (DaemonPreferences, DaemonTask)

I believe these are all the classes I need to create a custom daemon. If I'm mistaken please let me know as that would be the first mistake!

In the DaemonDataSourcePlugin, what does the `collect(self, config)` method is meant to do?

I understand the rest of the `on...` methods are callbacks for the Deferred, but the actual `collect` is meant to return a Deferred. Where must I create this Deferred, and what must the Deferred be?

I don't really understand what the Deferred that is returned must do.

In the DaemonTask class, what does the `doTask(self)` method do?

It would seem like `collect()` has to return a Deferred (which I do not know where it comes from), and then `doTask()` runs the `collect()` and adds the callbacks to handle errors and successes.

Essentially the question is, where does the actual collection code go?

My collection code will query a STOMP server, and for each query get a result. Should each query be a Task, or should all of the collection be one Task?

If you need any more information please do not hesitate in asking.

Thank you for your time.

Best regards,

Jose
