Prometheus

I use Prometheus to collect and store system and application metrics, enabling real-time monitoring and alerting. Its time-series database and powerful query language (PromQL) allow me to track performance trends, detect anomalies, and support incident response effectively. I value Prometheus for its reliability and native integration with Kubernetes and Grafana, making it ideal for observability in cloud and containerised environments. Whether monitoring resource utilisation, latency, or service health, Prometheus provides the foundation for data-driven operational insight.
