If the capacitor fails open, or high ESR, or loses
capacitance, the
ripple on that supply line will increase. A monitor could detect that,
but equally if that happens, the machine stops working correctly
.
The ripple can increase quite a bit before it causes failures. A
monitoring circuit can catch it before it gets that far.
