# Infrastructure and host monitoring
Explore the topics in this section to learn how to observe and monitor hosts and other systems running in your environment.
To work with metrics from any source, including Prometheus and custom application metrics, refer to [Metrics](https://www.elastic.co/elastic/docs-builder/docs/4547/solutions/observability/metrics).
<tip>
  We recommend using [Elastic Agent](https://www.elastic.co/elastic/docs-builder/docs/4547/solutions/observability/get-started/quickstart-monitor-hosts-with-opentelemetry) to collect infrastructure metrics and logs. You can also use the [Elastic Agent](https://www.elastic.co/elastic/docs-builder/docs/4547/solutions/observability/infra-and-hosts/get-started-with-system-metrics) with integrations for infrastructure monitoring.
