Get HystrixStats

[DavideCarvalho]

Is there any way of getting HystrixStats to open the stream url without opening a circuit?
I Tried the folowing code but it give's me an error "TypeError: Cannot read property 'name' of undefined"

const circuitBreaker = require('opossum');
const circuit = circuitBreaker().circuit;
const hystrixStats = circuit.hystrixStats;
module.exports = (app) => {
  Verification = async (req, res, next) => {
    res.writeHead(200, {'Content-Type': 'text/event-stream', 'Cache-Control': 'no-cache', 'Connection': 'keep-alive'});
    res.write('retry: 10000\n');
    res.write('event: connecttime\n');
  
    hystrixStats.getHystrixStream().pipe(res);
  }
}

@DavideCarvalho I don't understand why you would do this. The circuit in this case is never firing, so there is no data to pipe through the stream. That said, I don't think it should throw a TypeError in this case.

[DavideCarvalho]

In your example, you get the stream from only one circuit (at least i think it's from only one circuit, since you get the hystrixStatus from the circuit you just created), i'd like to know how aggregate all the stream so I can use on my url.

I will take a look, but I do not believe this is currently possible. Please feel free to submit a feature request for this, and I will look into it.

@DavideCarvalho there is an open pull request for this here #140. If you have feedback on this it would be welcome.

@DavideCarvalho can you confirm whether #140 addresses your concerns?
