Bug fixes and updates.

Advanced Warning

The following items are due to change in a future release.

  • Installation and Deployment

    • We intend to drop support for Java 17, making Java 21 the minimum. We plan to make this change in March 2024.

Improvements, new features and functionality

  • UI Changes

    • The Files page has a new layout and changes:

      • It has been split into two pages: one containing a list of files and one with details of each file.

      • A view limit of 100 MB has been added and you'll get an error in the UI if you try to view files larger than this size.

      • It displays information on the size limits and the step needed for syncing the imported files.

      For more information, see Files.

    • Parser test cases will automatically expand to the height of their content when loading the parser page now.

    • When selecting a parser test case, there is now a button to scroll to that test case again if you scroll away from it.

  • Automation and Alerts

    • LogScale now creates notifications for alerts and scheduled searches with warnings in addition to notifications for errors. The notifications for warnings will have a severity of warning.

  • Ingestion

    • A new mechanism is introduced that delays the response to a HTTP ingest request from nodes that also do digest when the digest node locally experiences digest lag. The following new dynamic configurations control this mechanism:

      • DelayIngestResponseDueToIngestLagMaxFactor limits how much longer than the actual execution it may be, measured as a factor on top of the actual time spent (default is 2).

      • DelayIngestResponseDueToIngestLagThreshold sets the number of milliseconds of digest lag where the feature starts to kick in (default is 20,000).

      • DelayIngestResponseDueToIngestLagScale sets the numer of milliseconds of lag that adds 1 to the factor applied (default is 300,000).

Bug Fixes

  • UI Changes

    • Turned the dropdown menu in the TablePage upwards and set it to the front to fix a bug where the menu would be hidden.

  • Storage

  • Dashboards and Widgets

    • The Gauge widget has been fixed as the Styling panel would not display configured thresholds.

  • Ingestion

    • A parser that failed to construct would sometimes result in events receiving a null error. This issue has been fixed.

    • A digest coordination issue has been fixed: it could cause minisegments to stay behind on old digest leaders when leadership changes.

  • Other

    • Occasional error logging from QueryScheduler.reduceAndSetSnapshot has been fixed.
