Availability time

I am using graphs with claudwatch from aws to capture all 5xx errors, I can get the service time unavailable tatal but I would like to be able to subtract by the selected date so that an availability time is shown, that is, how long that api does not show errors.
can anyone tell me if this is possible?

Howdy, Tempo is not capable of doing what you are asking about. Perhaps a metrics solution would be a better fit?
