Bug fixes and updates

Deprecation

Items that have been deprecated and may be removed in a future release.

  • The EXTRA_KAFKA_CONFIGS_FILE configuration variable has been deprecated and planned to be removed no earlier than version 1.225.0. For more information, see RN Issue.

  • rdns() has been deprecated and will be removed in version 1.249. Use reverseDns() as an alternative function.

Behavior Changes

Scripts or environment which make use of these tools should be checked and updated for the new configuration:

  • Storage

    • Changed the default value for AUTOSHARDING_MAX to 12,288 from 131,072 for a more conservative approach to prevent datasource explosion in Global Database. The new default value is based on observed autoshard maximums in cloud environments.

  • Configuration

    • The AUTOSHARDING_MAX configuration variable is no longer deprecated. It is retained as a safety measure against unlimited autoshard creation.

Upgrades

Changes that may occur or be required during an upgrade.

  • Installation and Deployment

    • Upgraded the Kafka client version to 4.1.0. This upgrade does not affect Kafka server version compatibility.

New features and improvements

  • Metrics and Monitoring

    • Added new metrics starvation-timer-<thread-pool>-<tid> and duration-timer-<thread-pool>-<tid> for default dispatchers, providing more detailed thread pool behavior analysis.

    • Added new metrics to track the total time spent on segment operations:

      • decompress-segment-query-total: total time spent on segment decompression for queries

      • load-segment-query-total: total time spent on segment loading for queries

    • Added additional node-level metrics to the humio-metrics option time-livequery, which measures the amount of CPU time used in static searches as a fraction of wall clock time:

      • time-query-decompress-segment

      • time-query-read-segment

      • time-query-map-segment

Fixed in this release

  • GraphQL API

  • Storage

    • Fixed an issue where merging segments could use excessive memory when processing events with large numbers of distinct fields. LogScale will now limit memory usage by stopping field extraction optimization when too many distinct field names are encountered.

      For more information, see Creating Segment files.

  • Metrics and Monitoring

    • Fixed an issue with time unit conversions for meter values in internal metrics reporting (introduced in v1.196), where due to incorrect unit conversion, values were off by a factor of 10^9. Only internal metrics exports were affected - logged metrics and Prometheus metrics were unaffected. Histogram metric labels were also corrected to show as HISTOGRAM instead of TIMER.

    • The node-level metric load-segment-total has been fixed as the computation did not include the time spent loading segments for queries and segment merging.

      For more information, see load-segment-total Metric.

Improvement

  • Queries

    • Improved the stability of multi-cluster search by implementing the retry logic for failed polls on certain types of exceptions.
