Grafana Cloud Application Observability vs Sentry Performance

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.

Sentry Performance is an application performance monitoring service for developers diagnosing bottlenecks in applications and distributed systems. It links performance problems with related errors, transactions, and code details to help teams assess user impact and investigate issues. Trace views and code context can help locate slow database queries, API calls, and associated code lines. Distributed tracing follows requests across services to help identify where latency or errors arise. Teams can prioritize performance issues by user impact and create custom metrics and alerts. Sentry lists integrations with GitHub, Jira, Slack, GitLab, Linear, Microsoft Teams, PagerDuty, Datadog, and Vercel, and supports OpenTelemetry. Its cloud service is hosted on Google Cloud Platform with a multi-tenant architecture; a self-hosted option is available for teams that need data in their own infrastructure. Trace retention is 90 days. The Developer plan costs nothing and has monthly usage quotas. Paid plans start at $26/mo; a free trial is available for Business, but not Team. Sentry makes its SOC 2 Type 2 report and ISO 27001 certificate available through user accounts or by request.
