Helper for exposing node-rdkafka statistics through prometheus
We are no longer using node-rdkafka, and are therefore not planning to add any features to this. We will still try to merge PRs to the best of our ability, of course.
const RdkafkaStats = require('node-rdkafka-prometheus');
const prometheus = require('prom-client');
// When setting up a consumer or producer:
const stream = rdkafka.KafkaConsumer.createReadStream({'statistics.interval.ms': 1000});
stream.consumer.on('event.stats', msg => {
const stats = JSON.parse(msg.message);
this.metrics.RDKAFKA_STATS.observe(stats);
