Sensu is the open source monitoring event pipeline built to reduce operator burden and make developers and business owners happy. Started in 2011, Sensu’s flexible approach solves the challenges of monitoring hybrid-cloud and ephemeral infrastructures with scalable, automated workflows and integrations with tools you already use. Get started now and feel the #monitoringlove: Learn Sensu Go.

Sensu Go is the latest version of Sensu, written in Go and designed to be more portable, easier and faster to deploy, and (even more) friendly to containerized and ephemeral environments. But above all, it was designed to support the features and functionality you’ve come to know and love about Sensu.

Automate your monitoring workflows: Limitless pipelines let you validate and correlate events, mutate data formats, send alerts, manage incidents, collect and store metrics, and more.

Reduce alert fatigue: Sensu gives you full control over your alerts with flexible filters, context-rich notifications, reporting, event handling, and auto-remediation.

Integrate anywhere: Sensu’s open architecture makes it easy to integrate monitoring with tools you already use like Nagios plugins, Chef, Graphite, InfluxDB, and PagerDuty.

Monitoring for Your Infrastructure

Monitoring is the action of observing and checking the behaviors and outputs of a system and its components over time. - Greg Poirier, Monitorama 2016

Sensu is an agent-based monitoring tool that you install on your organization’s infrastructure. The Sensu agent gives you visibility into everything you care about; the Sensu server gives you flexible, automated workflows to route metrics and alerts.

  • Monitor containers, instances, applications, and on-premises infrastructure

Sensu is designed to monitor everything from the server closet to the cloud. Install the Sensu agent on the hosts you want to monitor, integrate with the Sensu API, or take advantage of proxy entities to monitor anything on your network. Sensu agents automatically register and de-register themselves with the Sensu server, so you can monitor ephemeral infrastructure without getting overloaded with alerts.

  • Better incident response with filterable, context-rich alerts

Get meaningful alerts when and where you need them. Use event filters to reduce noise and check hooks to add context and speed up incident response. Sensu integrates with the tools and services your organization already uses like InfluxDB, Slack, and more. Check out the 200+ plugins shared by the Sensu community, or write your own Sensu Plugins in any language.

  • Collect and store metrics with built-in support for industry-standard tools

Know what’s going on everywhere in your system. Sensu supports industry-standard metric formats like Nagios Performance Data, Graphite Plaintext Protocol, InfluxDB Line Protocol, OpenTSDB Data Specification, and StatsD metrics. Use the Sensu agent to collect metrics alongside check results, then use the event pipeline to route the data to a time series database like InfluxDB.

  • Intuitive API and dashboard interfaces

Sensu includes a dashboard to provide a unified view of your entities, checks, and events, as well as a user-friendly silencing tool. The Sensu API and the sensuctl command-line tool allow you (and your internal customers) to create checks, register entities, manage configuration, and more.
