Central place to configure custom instrumentation

Problem Statement

Having to put decorators all over the code base to monitor their performance can be cumbersome.
A single place to set up custom instrumentation would be nice.

Solution Brainstorm

Have a list of functions that can be passed to "sentry_sdk.init()".
When the SDK starts it goes through the list and instruments all the functions in the list.

Something like this:

functions_to_trace = [
    {"qualified_name": "tests.test_basics._hello_world_counter"},
    {"qualified_name": "time.sleep"},
    {"qualified_name": "collections.Counter.most_common"},
]

sentry_sdk.init(
    dsn="...",
    traces_sample_rate=1.0,
    functions_to_trace=functions_to_trace,
)

This way you have one place to look what functions in your code base are custom instrumented.
