In some of the OneAgent features to be enable, what does the second toggle-button means?

Some of the features have only one toggle-button, which simply means it is either turn-on or turn-off. Easy.

Some of the features have a second toggle-button, for example like the one shown in screenshot below:

If the second toggle-button simply means a service-restart of the application-under-monitoring is required, then I was wondering why give users the option of toggle-on first one without toggle-on second one? Under what circumstances/use-case would we like to do that?

And if the second toggle-button doesn't simply means a service-restart is required, then what does it really means?

You actually can't enable a feature without enabling instrumentation. Instrumentation means code modifications in observed applications. This requires restarts as code modifications can't be accomplished safely at runtime.

Enabling the feature (the main flag) enables the feature itself. This does not require restarts, as the instrumentation is already there, and you can enable/disable the feature without restarts.

If you enable the feature without instrumentation, Dynatrace won't allow you to save such configuration:
