Cloudprober supercharges your monitoring with active probes (a.k.a. synthetic monitoring) to ensure your systems—homelabs, microservices, APIs, websites, or cloud-to-on-prem connections—run smoothly. See this post for why probers provide one of the most reliable monitoring signals.

Why Cloudprober?

• Versatile Probes: Built-in HTTP, PING, TCP, DNS, gRPC, and UDP probes, plus custom in-process scripts (Starlark) and external probes.

• Auto-Discover Targets: Effortlessly monitor Kubernetes, GCP, or file-based resources without constant redeployment.

• Integrate with Existing Systems: Out-of-the-box integration with Prometheus, Grafana, DataDog, AWS CloudWatch, PostgreSQL, and Google Cloud Monitoring.

• Easy Alerts: Stay informed via email, Slack, PagerDuty, OpsGenie, or any other HTTP based system.

• Lightweight & Scalable: Written in Go, compiles to a single binary, and runs efficiently as a standalone app or Docker container.

• Custom Metrics: Flexible latency histograms and configurable labels for precise insights.

• Extensible: Easily add new probe types, targets, or monitoring systems.

NOTE: Cloudprober's active development moved from google/cloudprober to cloudprober/cloudprober in Nov, 2021. We lost a bunch of Github stars (1400) in the process. See story of cloudprober to learn more about the history of Cloudprober.
