Grafana Cloud Application Observability vs Sematext Tracing

Grafana Cloud Application Observability monitors applications and brings OpenTelemetry and Prometheus data together to help software engineers investigate anomalies and their causes. Its knowledge graph discovers services and relationships from telemetry, while the service catalog displays latency, error ratio, and request rate for each service. The RCA workbench and Entity Graph help investigate correlated problems across a stack. Metrics, logs, traces, and profiles share a unified view, with drill-down from a service into its signals. Grafana identifies Alloy as a collector with native pipelines for OpenTelemetry and Prometheus. The free plan includes up to 2,232 host hours per month and community support. Pro is listed at $0.03 a month, with a $19 monthly platform fee and $0.025 per host hour; host hours and application telemetry are billed at standard Grafana Cloud rates. Serverless usage is billed on telemetry ingested instead of host hours. The cloud service runs on Linux, macOS, Windows, and the web.

Sematext Tracing is an OpenTelemetry-based distributed tracing service for monitoring and troubleshooting microservices and distributed systems. It accepts OTLP over HTTP or gRPC and works with OpenTelemetry Collectors, Jaeger, Zipkin, and compatible instrumentation. Users can filter traces by service, operation, latency, errors, or custom attributes, then inspect waterfalls and spans. Error rates, error types, and stack traces appear within the related request trace, while a Service Map depicts application dependencies and communication patterns. Performance views include latency breakdowns, P50/P95/P99 percentiles, RED metrics, and database query insights. Head-based sampling can retain errors and high-latency requests while sampling normal traffic at lower rates. Alerts can use latency thresholds, error rates, or custom span attributes. The product lists support for languages and frameworks including Java, Python, Go, .NET, Swift, Android, Spring, Django, Rails, React, Vue, and Svelte. Deployment options include Kubernetes, Docker, containers, or bare metal. Pricing is based on spans; the listed starting price is $17.10/mo (annual), and a 14-day trial is available without a credit card. There is no free plan.
