Trusted for production workloads by industry leaders

Why choose Sensu? Because the rules have changed.

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.

Observability Pipeline

With Sensu Go, you can fill gaps in observability between metrics, logging, & tracing. Consolidate existing monitoring tools, including Nagios, StatsD, Telegraf, Prometheus, & more.

Monitoring as code

Sensu Go codifies monitoring workflows into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.

Multi-cloud

Embrace auto-scaling with confidence & real-time visibility. Sensu automates the registration and de-registration of servers, containers, services, apps, functions, and connected devices.
