Cloudprober is a monitoring software that makes it super-easy to monitor availability and performance of various components of your system. Cloudprober employs the “active” monitoring model. It runs probes against (or on) your components to verify that they are working as expected. For example, it can run a probe to verify that your frontends can reach your backends. Similarly it can run a probe to verify that your in-Cloud VMs can actually reach your on-premise systems. This kind of monitoring makes it possible to monitor your systems' interfaces regardless of the implementation and helps you quickly pin down what’s broken in your system.

Cloudprober Use Case


  • Multiple options for checks:

  • Automated targets discovery to make Cloud deployments as painless as possible:

    • Kubernetes resources.
    • GCP instances, forwarding rules, and pub/sub messages.
    • File based targets.
  • Deployment friendly:

    • Written entirely in Go, and compiles into a static binary.
    • Deploy as a standalone binary, or through docker containers.
    • Continuous, automated target discovery, to ensure that most infrastructure changes don’t require re-deployment.
  • Low footprint. Cloudprober takes advantage of the Go’s concurrency paradigms, and makes most of the available processing power.
  • Configurable metrics:

    • Configurable metrics labels, based on the resource labels.
    • Latency histograms for percentile calculations.
  • Extensible architecture. Cloudprober can be easily extended along most of the dimensions. Adding support for other Cloud targets, monitoring systems and even a new probe type, is straight-forward and fairly easy.
