Public cloud and cloud-native computing have made automation the order of the day, but configuration management and Kubernetes foster high-velocity changes that outpace traditional monitoring tools. Regain control with Sensu, and join thousands of companies who enjoy monitoring at the speed of automation.

The shift from static to dynamic infrastructure requires a change in approach to monitoring, from host-based to functional role-based. Connectivity moves from remote polling to publish-subscribe, the control plane moves from point-and-click interfaces to infrastructure-as-code workflows and self-service developer APIs.
Embrace auto-scaling with confidence & real-time visibility. Sensu automates the registration and de-registration of servers, containers, services, apps, functions, and connected devices.
Sensu Go codifies monitoring workflows into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.
Sensu Go was designed from the ground up for self-service workflows with features like deeply-embedded role-based access controls (RBAC) and namespaces.
Get Sensu up and running in as little as 15 minutes. In fact, you may be able to take the first steps in under a minute! Don’t believe us? Give the following quick start guide a try, and let us know if we can help!
Deploy our official Docker container to get up and running in seconds. Follow these steps, then visit your Sensu Go dashboard at http://localhost:3000/.

Sensu makes it easy to deploy instrumentation (e.g. plugins or scripts) and configure new monitors. This example shows how to monitor system clock drift.

Traditional monitoring tools are cost-prohibitive to operate at even moderate scale, and legacy monitoring tools are incompatible with the ephemeral nature of public cloud and cloud-native platforms. Upgrade to Sensu today to embrace your multi-cloud operation with confidence – and without breaking the budget!
