    stabilizeAfterNSuccesses: 2,
};
const b = new CircuitBreaker(conf);
b.start();

const i = setInterval(() => {
    if (b.state === BreakerState.Nominal) {
        console.log('all good, proceeding');
    } else {
        console.log('issue detected, delaying work');
    }
}, 5000);

process.on('beforeExit', (code) => {
