Known issues

edit
Azure EventHub input for Elastic Agent fails to start on Windows

Details

The Azure EventHub input fails to start on Elastic Agent version 8.15 running on Windows. The Elastic Agent status will be reported as unhealthy. See Beats issue #40608 for details.

Impact

If you’re using Elastic Agent on Windows with any integration which makes use of the Azure EventHub input, we recommend not upgrading Elastic Agent to version 8.15.0 and instead waiting for a later release. A fix is planned for version 8.15.1.

The memory usage of Beats based integrations is not correctly limited by the number of events actively in the memory queue, but rather the maximum size of the memory queue regardless of usage.

Details

In 8.15, events in the memory queue are not freed when they are acknowledged (as intended), but only when they are overwritten by later events in the queue buffer. This means for example if a configuration has a queue size of 5000, but the input data is low-volume and only 100 events are active at once, then the queue will gradually store more events until reaching 5000 in memory at once, then start replacing those with new events.

See Beats issue #41355.

Impact

Memory usage may be higher than in previous releases depending on the throughput of Elastic Agent. A fix is planned for 8.15.4.

  • The worst memory increase is for low-throughput configs with large queues.
  • For users whose queues were already sized proportionate to their throughput, memory use is increased but only marginally.
  • Affected users can mitigate the higher memory usage by lowering their queue size.

New features

edit

The 8.15.0 release Added the following new and notable features.

Fleet Server
  • When Fleet Server runs in elastic-agent mode, it’s now able to use the enrollment configuration options in output.elasticsearch.bootstrap from its policy, instead of overwriting the matching keys in output.elasticsearch. #3506 #3464
