## Metrics with Prometheus 🔦
Prometheus is become the standard de facto for self-hosted monitoring in part thanks to his architecture. It's a TSDB (Time Series Database) that will poll (aka scrape) standard metrics REST endpoints, provided by the tools to monitor. It's the case of Traefik, as we seen in [part III]({{< ref "04-build-your-own-docker-swarm-cluster-part-3#traefik-" >}}). For tools that don't support it natively, like databases, you'll find many exporters that will do the job for you.
