Grafana Cloud Application Observability vs Paessler PRTG Database Monitoring

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.

Paessler PRTG Database Monitoring tracks database availability, errors, and query performance across Microsoft SQL Server, MySQL, PostgreSQL, Oracle, Azure SQL Database, AWS RDS, and ODBC/ADO-compatible databases. Its sensors measure complete-request time and query execution time separately in milliseconds. You can run custom SQL queries on a schedule and map results to monitoring channels. PRTG can flag connection timeouts, authentication failures, service interruptions, and query-validated errors; threshold alerts can go by email, SMS, push notification, syslog, or webhook.

Azure SQL Database and AWS RDS sensors collect metrics through Azure Monitor and AWS CloudWatch APIs without an agent on the database host. Scan intervals are configurable, with Paessler recommending five minutes for production monitoring. Backup checks use custom queries against backup history tables or file timestamps and require query-level setup. PRTG is offered as a Windows download or cloud-hosted service. Platforms listed include web, Windows, Android, iOS, and self-hosted deployment. A free plan covers up to 100 sensors; paid plans start at $200/mo (annual), and the free trial lasts 30 days.
