Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[6.4.1] - 2021-08-24

Added

• Added ignore-already-initialized configuration flag to the sensu-backend init command for returning exit code 0 when a cluster has already been initialized.
• Added javascript mutators, which can be selected by setting "type": "javascript" on core/v2.Mutators, and specifying valid ECMAScript 5 code in the "eval" field. See documentation for details.
• Added --retry-min, --retry-max, and --retry-multiplier flags to sensu-agent for controlling agent retry exponential backoff behaviour. --retry-min and --retry-max expect duration values like 1s, 10m, 4h. --retry-multiplier expects a decimal multiplier value.
• Added ProcessedBy field to check results. The ProcessedBy field indicates which agent processed a particular event.
• Added core/v2.Pipeline resource for configuring Pipeline resources.- Added pipelines field to Check and CheckConfig
• Added API key support for admin user at cluster init time.
• Added sensu_go_agentd_event_bytes & sensu_go_store_event_bytes summary metrics to the /metrics endpoint.
• Added support for environment variable arguments in sensuctl.

Changed

• When deleting resource with sensuctl, the resource type will now be displayed in the confirmation prompt
• When keepalived encounters round-robin ring errors, the backend no longer internally restarts.
• The core/v2.Mutator type now has a Type field which can be used to tell Sensu that the mutator is a different type from the default (pipe). Currently, the supported types are "pipe" and "javascript".
• The default retry values have been increased from a minimum of 10ms to 1s, a maximum of 10s to 120s, and the multiplier decreased from 10.0 to 2.0.
• The backend internal bus default buffer sizes have been increased from 100 to 1000 items.

Fixed

• Sensu Go OSS can now be built on darwin/arm64.
• Fixed a regression in sensu-backend init where the exit status returned 0 if the store was already initialized.
• Guard against potential crash in the sensuctl cluster member-list command when the etcd response header is nil.
• Agent events API now accepts metrics event.
• Fixed rare cases where the agent could fail to delete temporary files when downloading assets.

• Backend now reports when it is ready to process events at warn level.

[6.4.0] - 2021-06-23

Added

• Added etcd-log-level configuration flag for setting the log level of the embedded etcd server.

Fixed

• Fixed config deprecation warnings from being shown when deprecated config options weren't set.
• Fixed issue with keepalive status remaining in OK status after agent shutdown.

Added

• [Web] Added an additional option to the error dialog allowing users to completely wipe the application's persisted state; in lieu of them having to manually wipe their local / session storage. This may help in the rare cases where something in said state is leading to an uncaught exception.
• [Web] For operating systems with support for selecting a preferred light /dark theme, the application now respects the system preference by default.
• sensuctl dump can now list the types of supported resources with --types.
• Added the sensu_agent_version field to the Entity resource, which reflects the Sensu semver version of the agent entity.

• [Web] When a user lands on a page inside a namespace that no longer exists or they do not have access to, the drawer is now opened so that namespace switcher is front and center. Hopefully this should reduce any confusion around next steps.

• Fixed a bug where sensuctl create with stdin was not working.

[5.13.2] - 2019-09-19
