Cloudprober

cloudprober.org

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

Features

  • Integration with open source monitoring stack of Prometheus and Grafana. Cloudprober exports probe results as counter based metrics that work well with Prometheus and Grafana.
  • Automated target discovery for Cloud targets. GCP is supported out-of-the-box; other Cloud providers can be added easily.
  • Integration with StackDriver. If configured, Cloudprober exports probe results to StackDriver as custom metrics.
  • Built-in implementations for the most common probe types: PING, HTTP, UDP, DNS.
  • Arbitrary, complex probes can be run through the external probe type. For example, you could write a simple script to insert and delete a row in your database, and execute this script through the 'EXTERNAL' probe type.
  • Fast and efficient ping prober implementation that allows probing thousands of hosts with minimal resources.
  • Strong focus on ease of deployment. Cloudprober is written entirely in Go and compiles into a static binary. It can be easily deployed through docker containers. Thanks to the automated target discovery, there is usually no need to re-deploy or re-configure cloudprober in response to the most of the changes.
  • Go templates based config file with substitutions for standard variables like project, zone, instance names etc allows for using same config file across the fleet.
  • Low footprint. Cloudprober docker image is small, containing just the statically compiled binary and it takes very little CPU and RAM to run even a large number of probes.
  • Extensible architecture. Cloudprober can be easily extended along most of the dimensions. Adding support for other Cloud targets, monitoring systems (e.g. Graphite, Amazon Cloudwatch) and even a new probe type, is straight-forward and fairly easy.

Documentation

Overview

Package cloudprober provides a prober for running a set of probes.

Cloudprober takes in a config proto which dictates what probes should be created with what configuration, and manages the asynchronous fan-in/fan-out of the metrics data from these probes.
