Known Issues

edit

Affecting all Beats

  • Disk queue filled metrics can underflow after blocked publishes. When a disk queue reaches its configured capacity, inputs can block until the output acknowledges events. The queue then accepts the blocked event without updating its metrics. When the event is later removed, the queue.filled.events, queue.filled.bytes, and queue.filled.pct metrics might report incorrect values. Event delivery is unaffected. Upgrade to 8.19.21 or later to apply the fix.

Filebeat

  • Filestream "take over" mode does not work in versions 8.19.0-8.19.20. A fix will ship in the 8.19.21 release.
