Hi,
Below is the change related to logging of the units (service) while changing the state [in]active_[exit/enter].
I did not get any hint from source code, to know the state change using function, without querying the target system through CLI.
Could someone from the forum help in providing a hint on how to get the state of the services without querying through CLI.
Instead of below changes, is there any alternative modification i can do to know the state of the service.
