Fleet and Elastic Agent 8.4.0edit

Review important information about the Fleet and Elastic Agent 8.4.0 release.

Breaking changesedit

Breaking changes can prevent your application from optimal operation and performance. Before you upgrade, review the breaking changes, then mitigate the impact to your application.

xpack.agents.* are uneditable in UI when defined in kibana.yml

Details
When you configure setxpack.fleet.agents.fleet_server.hosts and xpack.fleet.agents.elasticsearch.hosts in kibana.yml, you are unable to update the fields on the Fleet UI. For more information, refer to #135669.

Impact
To configure setxpack.fleet.agents.fleet_server.hosts and xpack.fleet.agents.elasticsearch.hosts on the Fleet UI, avoid configuring the settings in kibana.yml.

Known issuesedit

Credentials error prevents Elastic Agent from ingesting AWS logs

Details

Elastic Agents configured to use the AWS integration may return an error similar to the following:

sqs ReceiveMessage failed: operation error SQS: ReceiveMessage, https response
error StatusCode: 403, RequestID: cb57783a-505f-5099-9160-23b8eea8ddbb,
api error SignatureDoesNotMatch: Credential should be scoped to a valid region.

This error was introduced by a breaking change in the AWS library.

Impact

Elastic Agent is unable to ingest AWS logs and some metrics. To resolve this error:

  • If you are using the default domain amazonaws.com, upgrade the AWS integration package to version 1.23.4 to apply the temporary fix added in PR #4103. If this does not solve your problem, set the AWS region (either from an environment variable, credentials or instance profile) where Elastic Agent is running.
  • Otherwise, wait to upgrade until the permanent fix added by PR #32921 is available in an upcoming stack release.
