Bug fixes and updates
Deprecation
Items that have been deprecated and may be removed in a future release.
AUTOSHARDING_MAXconfiguration variable is now being deprecated and will be removed in version 1.207.The
EXTRA_KAFKA_CONFIGS_FILEconfiguration 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. UsereverseDns()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_MAXto 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_MAXconfiguration 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>andduration-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
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.
GraphQL API
Fixed an issue where the GraphQL mutation createPersonalUserTokenV2 would fail with an unspecified error message.
For more information, see createPersonalUserTokenV2() .
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 ???.
Improvement
Queries
Improved the stability of multi-cluster search by implementing the retry logic for failed polls on certain types of exceptions.
