Bug fixes recommended for all customers.

Deprecation

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

• The server.tar.gz release artifact has been deprecated. Users should switch to the OS/architecture-specific server-linux_x64.tar.gz or server-alpine_x64.tar.gz, which include bundled JDKs. Users installing a Docker image do not need to make any changes. With this change, LogScale will no longer support bringing your own JDK, we will bundle one with releases instead.

  We are making this change for the following reasons:

  • By bundling a JDK specifically for LogScale, we can customize the JDK to contain only the functionality needed by LogScale. This is a benefit from a security perspective, and also reduces the size of release artifacts.

  • Bundling the JDK ensures that the JDK version in use is one we've tested with, which makes it more likely a customer install will perform similar to our own internal setups.

  • By bundling the JDK, we will only need to support one JDK version. This means we can take advantage of enhanced JDK features sooner, such as specific performance improvements, which benefits everyone.

  The last release where server.tar.gz artifact is included will be 1.154.0.

• The HUMIO_JVM_ARGS environment variable in the LogScale Launcher Script script will be removed in 1.154.0.

  The variable existed for migration from older deployments where the launcher script was not available. The launcher script replaces the need for manually setting parameters in this variable, so the use of this variable is no longer required. Using the launcher script is now the recommended method of launching LogScale. For more details on the launcher script, see LogScale Launcher Script. Clusters that still set this configuration should migrate to the other variables described at Configuration.

• The lastScheduledSearch field from the ScheduledSearch datatype is now deprecated and planned for removal in LogScale version 1.202. The new lastExecuted and lastTriggered fields have been added to the ScheduledSearch datatype to replace lastScheduledSearch.

Behavior Changes

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

• Functions

  • Prior to LogScale v1.147, the array:length() function accepted a value in the array argument that did not contain brackets [ ] so that array:length("field") would always produce the result 0 (since there was no field named field). The function has now been updated to properly throw an exception if given a non-array field name in the array argument. Therefore, the function now requires the given array name to have [ ] brackets, since it only works on array fields.
