Monitoring Caddy, MinIO, NATS, and ScyllaDB with OpenObserve Dashboards

Monitoring distributed infrastructure is crucial, and this guide details the process of creating production monitoring dashboards for OpenObserve, emphasizing the integration pipeline from metrics collection to visualization. It covers the use of four services—Caddy, MinIO, NATS, and ScyllaDB—commonly found together in modern systems, with each component playing a specific role such as edge proxy, object storage, messaging, and NoSQL database, respectively. The guide explains how to establish a flow of metrics using Prometheus-compatible endpoints and the OpenTelemetry Collector, which scrapes these endpoints and forwards the data to OpenObserve. It also discusses the structure of OpenObserve dashboards, including JSON schema, panel types, and layout systems, alongside techniques for writing effective PromQL queries and utilizing dynamic filters for comprehensive observability. Understanding these elements is essential for building scalable, actionable, and insightful dashboards that facilitate quick interpretation and system health monitoring.
