Stats for Hypercores, with Prometheus support.
Assumes the hypercores are replicated over UDX streams. This is the case for all normal use-cases of hypercores (like replicating across hyperdht/hyperswarm).
npm i hypercore-stats
const Corestore = require('corestore')
const HypercoreStats = require('hypercore-stats')
const promClient = require('prom-client')
const store = new Corestore('dummy-corestore')
const hypercoreStats = HypercoreStats.fromCorestore(store)
hypercoreStats.registerPrometheusMetrics(promClient)
// The Prometheus metrics are typically exposed to a metrics scraper
const metrics = await promClient.register.metrics()
console.log(metrics)
