How to get default alert rules in a central place? How can I know the thresholds for each enabled monitoring items?

How to get default alert rules in a central place? How can I know the thresholds for each enabled monitoring items?

I checked the WEB API, there is none. Can anyone show me how to create own api and query parameters to get default alert rules?

nobody has experience? :frowning:

all defaults saved in check code like variable factory_defaults.
How to query them - no idea.
