Grafana, Prometheus, and Loki Replace Datadog for the Price of an Old PC Under Your Desk

Datadog charges $15 per host per month for infrastructure, $31 for APM, and $0.10 per gigabyte of ingested logs. Grafana, Prometheus, Loki, and node_exporter deliver the same coverage on a single Docker Compose stack, on Linux or Windows, for the cost of hardware and electricity.
