Monitoring for mission-critical systems.

Sensu offers licensed features designed to satisfy production-grade scalability, enterprise integrations, and bulletproof security requirements for monitoring your multi-cloud infrastructure.

Why choose Sensu?

The shift from static to dynamic infrastructure introduces new business requirements. High-trust private networks are replaced with untrusted networks on public clouds. Tightly coupled ops tools are being displaced with disparate systems, necessitating integration with third-party APIs. Collaboration between development and operations relies on self-service workflows with integrated authentication solutions.

Scalable

Monitor tens of thousands of nodes from a single cluster using Sensu’s high-performance enterprise datastore. Get visibility into globally distributed infrastructure with Sensu federation.

Integrated

Onboard new teams quickly with turn-key integrations for the tools your organization relies on, including Elasticsearch, Splunk, PagerDuty, ServiceNow, Ansible Tower, and many more.

Secure

Lock down user access with Sensu SSO providers (LDAP, Active Directory, OIDC), and automate agent identity with mTLS certificate authentication, external PKI verification, and CRL support.

Enterprise-grade features designed for production workloads.

Level up your monitoring with mission-critical features and integrations.

Architected for organizational and technical scalability.

Monitor tens of thousands of nodes from a single Sensu cluster with an enterprise data store (PostgreSQL). Get visibility into regionally or globally distributed infrastructure with a single pane of glass using Sensu federation. With Sensu’s robust multi-tenant architecture, multiple development and operations teams can collaborate on a single Sensu cluster.

Consolidate observability tools with turn-key integrations.

Sensu integrates with the platforms and tools you're already using to eliminate data silos, improve observability, and reduce multi-cloud tool sprawl. Send metrics to Elasticsearch, Splunk, InfluxDB, and more while creating and resolving incidents in PagerDuty, ServiceNow, and VictorOps. Automate inventory using ServiceNow or other third-party CMDBs. Trigger self-healing workflows with the Ansible Tower integration.

Bulletproof security solutions.

Unlock self-service workflows with confidence. Grant every team access to the right monitoring data with Single Sign-On (SSO). Automate agent identity in the public cloud with mutual-TLS certificate authentication, external PKI verification, and CRL support.

Supercharge your operations team for less than 1¢ per node per hour.

Downtime is expensive! When it comes to operating production workloads, saving a few dollars per year by choosing free monitoring tools isn’t worth the risk. Activate your Sensu cluster today to unlock the scalability, integrations, and security features your organization demands.
