Questions on custom script programming

[mburggraf]

Hello.

I'm writing a few custom scripts for our netbox instance. Though the official documentation is not very verbose on this part.
Currently there are two questions, which I didn't find an answer yet. Maybe someone can help me on this part:

1. Is there a way for a custom script to identify if it was run manually via GUI, or by a scheduled_task? (Or maybe even as event_rule)
2. Can a custom script access its own logs? I mean if I use self.log_success/self.log_info/… during a script, is there a way to read these messages later, before ending the script, to do additional tasks? (Like counting the number of log_failures and act on the result, or do some reformatting?)

Would be nice if someone knows the answers.

A few days later, and I'm basically able to answer my own questions. 🤣
So in case anyone else stumbles upon this thread, here what I found out:

1. I couldn't find an official way to determine on how the script was run. However I noticed that when creating an event rule, you can pass additional data via the action_data field. So when entering something like
   {"run_by": "event_rule"}
   the script can check for this variable.
   With the REST-API it's also possible to add additional fields, so we can check this as well. (Though running the script from CLI with ./manage.py runscript will remove any unknown variable!) The thing is: When scheduling the task to repeat regularly via REST-API, the tasks will get the same parameters for every run, which makes it possible to let the script know it was run by such a task.
   I don't know if there is a better way, but this is enough for me.
2. Logs can be accessed via self.messages inside the script, which is just a list of dictionaries containing all logged messages so far.
