problem description

the company asked for some information about the project. Among them, the healthy running time of the project, I do not know how to solve it.

the environmental background of the problems and what methods you have tried

the Django project has been deployed on the server with Apache.
healthy running time, which, according to the relevant documentation, is generally the difference between the current time and the initial login time; both times are easy to obtain.
if the server is restarted, the healthy runtime must be recalculated. The problem now is that it is not possible to detect whether the project has been restarted in the project.
that is, the time information related to the start and end of django or apache cannot be read in the program code.
has tried to read apache"s log file, but it is not feasible to filter through text content.

I would like to ask all of you, is there any good way or idea to detect whether the project has started or ended? Thank you
