Prometheus

Prometheus is the CNCF graduated monitoring and alerting toolkit, featuring a multi-dimensional data model with time-series metrics, PromQL, and native OpenTelemetry ingestion.

When to Use

• Cloud-Native Time-Series Monitoring: Scraping, storing, and querying numerical metrics from infrastructure and applications.
• PromQL Quantitative Querying: Computing request rates, 99th percentile latencies, error ratios, and saturations.
• Automated Service Discovery: Dynamically discovering Kubernetes pods, EC2 instances, and Consul nodes to scrape.
• Alerting Rules & Alertmanager Integration: Evaluating threshold rules and dispatching alerts to on-call engineers.
