I never said 1 cent payment. I didn't know diddly squat about what your domain was or any specifics. You just said that that was a good case of 'bad monitoring is OK'. It's not. Maybe your hands are tied, I'll give you that. It won't make it good though. Also I said 'this space intentionally left blank'. Whatever actual form that would take in your example. Just because multiple entities use the same interface does not mean a bad interface is suddenly a good interface. To take an analogy and stay in payments (not sure what your specifics are). If your live system for CC processing OKs a payment from 4111 1111 1111 1111 you're toast. Your system better only 'process' that in a test environment. Perfect for a dummy row that gets ignored but ensures your monitoring does not trigger. And yes, been there, done that too with these file based interfaces. (it's funny how some systems that don't actually process your payment right away actually let you book with a known dummy CC - in Prod. Technically OK because you'll pay for real later - think hotel. Still funny)
