Grafana Cloud Application Observability vs MetricFire

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.

MetricFire is a web and API service that runs Graphite and Grafana for monitoring metrics, dashboards, and alerting. Custom application metrics can arrive over TCP, UDP, HTTP POST, or StatsD without an agent or SDK. Built-in Graphite alerting connects with Slack, PagerDuty, and email. Listed integrations include AWS, Azure, Google Cloud Platform, Heroku, Telegraf, Prometheus, Redis, and PostgreSQL, alongside Kubernetes, serverless, and synthetic monitoring. Intro costs $16 a month billed annually and includes 500 metrics, six-month retention, 30-second resolution, two team users, 10 alerts, and unlimited dashboards. Basic is $84 a month billed annually with 1,000 metrics and two-year retention; Core is $429 a month billed annually with 5,000 metrics and the same listed allowances. A custom plan is available by contacting MetricFire. There is no free plan, but a 14-day trial is offered.
