5.3.0 release notes
March 11, 2019 — The latest release of Sensu Go, version 5.3.0, is now available for download. This release has some very exciting feature additions and key bug fixes. 5.3.0 enables Active Directory to be configured as an authentication provider with a valid license key. Additionally, round robin scheduling has been fully re-implemented and is available for use. See the upgrading guide to upgrade Sensu to version 5.3.0.
Changes to Sensu Go
- Round-robin check scheduling lets you distribute check executions evenly over a group of Sensu agents. To enable round-robin scheduling, set the
round_robincheck attribute to
true. See the check reference for more information.
- Sensu now provides enterprise-only support for using Microsoft Active Directory as an external authentication provider. Read the authentication guide to configure Active Directory, and check out the getting started guide for more information about licensing.
- The dashboard now features offline state detection and displays an alert banner in the event that the dashboard loses connection to the backend.
- The agent socket event format now supports the
handlersattribute, giving you the ability to send socket events to a Sensu pipeline. See the agent reference to learn more about creating and handling monitoring events using the agent socket.
- Assets now feature improved download performance using buffered I/O.
- The sensuctl CLI now uses a 15-second timeout period when connecting to the Sensu backend.
- The dashboard now includes expandable configuration details sections on the check and entity pages. You can now use the dashboard to review check details like command, subscriptions, and scheduling, as well as entity details like platform, IP address, and hostname.
- Sensu Go 5.3.0 fixes all known TLS vulnerabilities affecting the backend, including increasing the minimum supported TLS version to 1.2 and removing all ciphers except those with perfect forward secrecy.

- The backend no longer requires the
trusted-ca-fileflag when using TLS.
- The backend no longer loads server TLS configuration for the HTTP client.

- The agent now communicates entity subscriptions to the backend in the correct format.
