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.
- Beats Docker images do not log to stderr by default. The workaround is to pass the CLI flag -e or to set logging.to_stderr: true in the configuration file. 41118

The Filestream input does not enforce the restrictions documented for the clean_inactive option, thus allowing configurations that can lead to data re-ingestion issues.
When clean_inactive: 0, Filestream cleans the state of all files on start up, effectively re-ingesting all files on restart. Set clean_inactive to a very large value. For example, use clean_inactive: 43800h0m0s, which is 5 years.
