prometheus query tester
📊 Prometheus Query Tester
PromQL (Prometheus Query Language) is powerful but often complex for newcomers and even experienced SREs. The Prometheus Query Tester tool lets you experiment with PromQL-like expressions in a simulated way, without needing a Prometheus server. Ideal for quick tests, workshops, learning metric patterns, or practicing alert logic.
This tool simulates how a Prometheus-like system would evaluate basic vector expressions, aggregation, filters, and labels. While it doesn’t query live metrics, it is a safe and effective space to refine your logic before applying it in a real Grafana/Prometheus/Alertmanager setup.
