TL;DR

Vendor-aware tool evaluation for Kubernetes observability. Prometheus+Grafana remains dominant (80%+ adoption) due to Kubernetes-native design and zero licensing. SaaS options (Datadog, Grafana Cloud, New Relic) offer managed infrastructure at cost trade-off. SigNoz emerging as OpenTelemetry-native open-source alternative. Kubecost fills the gap for cost visibility and right-sizing. Decision framework provided for team size/budget.

Signal

• Industry benchmark: 80%+ of Kubernetes clusters use Prometheus; PromQL is the de facto metrics query language
• Datadog dominance: full-stack (metrics, traces, logs, APM) in one UI; costs scale with cardinality and log volume
• Open-source shift: SigNoz and Prometheus+Grafana+Thanos+Loki+Tempo enable full-stack observability without vendor lock-in
• Kubernetes cost visibility: Kubecost allocates spending by namespace/deployment/pod; enables shared engineering-finance accountability
• Managed option growth: Grafana Cloud reduces operational burden (Prometheus/Mimir/Loki/Tempo) with generous free tier

What They're NOT Telling You

This is a tool guide, not strategic advice. The assumption that teams can/should run Prometheus+Grafana glosses over the significant operational burden (Thanos for long-term storage, Alertmanager config, eBPF tuning). Cost comparisons are surface-level (Datadog $23/host is accurate but scales explosively with high-cardinality metrics). The article doesn't address hybrid approaches (e.g., Prometheus for metrics, Datadog for logs) or discuss observability maturity as a prerequisite for tool selection.
