Sensu v0.28.0 Release Notes

Release Date: 2017-02-23 // about 7 years ago

  • 🛠 Fixed

    • ⏱ The Sensu interval timers, used for scheduling tasks, now account for drift. The check request and standalone execution scheduler timers are now more accurate.
    • 🛠 Fixed a bug in the Sensu deep_merge() method that was responsible for mutating arrays of the original provided objects.

    ➕ Added

    • 🔧 Added proxy check requests to improve Sensu's ability to monitor external resources that have an associated Sensu proxy client. Publish a check request to the configured subscribers (e.g. ["round-robin:snmp_pollers"]) for every Sensu client in the registry that matches the configured client attributes in client_attributes on the configured interval (e.g. 60). Client tokens in the check definition (e.g. "check-snmp-if.rb -h :::address::: -i eth0") are substituted prior to publishing the check request. The check request check source is set to the client name.
    • ⏱ Schedule check requests and standalone executions with the Cron syntax.
    • ➕ Added the Sensu server registry, containing information about the running Sensu servers. Information about the Sensu servers is now accessible via the Sensu API /info endpoint.
    • ➕ Added two optional attributes to Sensu API POST /request, "reason" and "creator", for additional context. The check request reason and creator are added to the check request payload under "api_requested" and become part of the check result.
    • ➕ Added event IDs to event handler log events for additional context, making it easier to trace an event through the Sensu pipeline.
