hypercore-stats v2.1.0

Hypercore Stats

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).

Install

npm i hypercore-stats

Versions

• V1 works for Hypercore V10 and Corestore V6
• V2 works for Hypercore V11 and Corestore V7

Usage

const Corestore = require('corestore')
const HypercoreStats = require('hypercore-stats')
const promClient = require('prom-client')

const store = new Corestore('dummy-corestore')

const hypercoreStats = await HypercoreStats.fromCorestore(store)
hypercoreStats.registerPrometheusMetrics(promClient)

// The Prometheus metrics are typically collected by a metrics scraper, but we just print them here to illustrate
const metrics = await promClient.register.metrics()
console.log(metrics)

Usage Without Prometheus

hypercoreStats.toString() returns a string representation of all stats.
