July 11, 2017 — Sensu Core version 1.0.0 has been released and is available for immediate download. Please note the following improvements:
IMPORTANT: Sensu packages now include Ruby 2.4.1. Upgrading from prior versions of Sensu will require any plugin or extension gems to be re-installed under the new Ruby environment.
IMPORTANT: Sensu packages now include sensu-plugin 2.0.0, which
disables its deprecated filter methods by default, i.e.
occurrences. Sensu 1.0 includes built-in filters that provide the
same functionality with several improvements. The built-in filters
are “occurrences” and “check_dependencies”. To use the
built-in filters, apply them to Sensu event handlers via their
"filters" attribute, e.g.
"check_dependencies"]. These filters can now be used with Sensu
event handlers that do not use the sensu-plugin library (or Ruby).
NEW: Added Sensu API event endpoint alias “incidents”, e.g. /incidents, /incidents/:client/:check.
IMPROVEMENT: Improved Sensu client keepalive configuration validation, now including coverage for check low/high flap thresholds etc.
IMPROVEMENT: Improved Sensu client socket check result validation, now including coverage for check low/high flap thresholds etc.
IMPROVEMENT: The sensu-install tool now notifies users when it is unable to successfully install an extension, when the environment variable EMBEDDED_RUBY is set to false.
IMPROVEMENT: Added the Sensu RELEASE_INFO constant, containing information about the Sensu release, used by the API /info endpoint and Server registration.
BUGFIX: Sensu handler severities filtering now accounts for flapping events.
BUGFIX: Fixed Sensu Redis connection on error reconnect, no longer reusing the existing EventMachine connection handler.
