SQL Exporter
Monitoring & StatusDatabase-agnostic Prometheus exporter driven by custom queries
Replaces Datadog Custom Metrics, New Relic Query Insights
Datadog Custom Metrics is a popular proprietary tool in the monitoring & status space. These open-source apps let you replace Datadog Custom Metrics with software you host and control yourself.
Moving off Datadog Custom Metrics means trading a managed subscription for a service you run yourself. The payoff is ownership: no per-seat pricing, no vendor lock-in, and full control of your data. Start with the option above that matches your setup-difficulty comfort level — every app links to a detailed specs page and head-to-head comparisons.
