Local check data livetime

That was my question: Is there a way to alert if the data is too old?

I expect a run time of 60 sec, so I put it into the 90 folder. But what happens if the script does not work as expected? Currently there is no indication for me when I do it the way I did it.

Could you give some more explanation or link to the documentation? I don’t understand what you try to tell me.
