Bug fixes and updates.
Advance Warning
The following items are due to change in a future release.
Installation and Deployment
The LogScale Launcher Script script for starting LogScale will be modified to change the way CPU core usage can be configured. The
-XX:ActiveProcessorCount=n
command-line option will be ignored if set. Users that need to configure the core count manually should setCORES=n
environment variable instead. This will cause the launcher to configure both LogScale and the JVM properly.This change is scheduled for 1.148.0.
For more information, see Configuring Available CPU Cores.
Deprecation
Items that have been deprecated and may be removed in a future release.
The
any
argument to thetype
parameter ofsort()
andtable()
has been deprecated and will be removed in version 1.142.Warnings prompts will be shown in queries that fall into either of these two cases:
If you are explicitly supplying an
any
argument, please either simply remove both the parameter and the argument, for example changesort(..., type=any)
tosort(...)
or supply the argument fortype
that corresponds to your data.If you are sorting hexadecimal values by their equivalent numerical values, please change the argument of
type
parameter tohex
e.g.sort(..., type=hex)
.In all other cases, no action is needed.
The new default value for
sort()
andtable()
will benumber
. Both functions will fall back to lexicographical ordering for values that cannot be understood as the provided argument fortype
.The following API endpoints are deprecated and marked for removal in 1.148.0:
POST
/api/v1/clusterconfig/kafka-queues/partition-assignment
GET
/api/v1/clusterconfig/kafka-queues/partition-assignment
POST
/api/v1/clusterconfig/kafka-queues/partition-assignment/set-replication-defaults
The deprecated methods are used for viewing and changing the partition assignment in Kafka for the ingest queue. Administrators should use Kafka's own tools for editing partition assignments instead, such as the bin/kafka-reassign-partitions.sh and bin/kafka-topics.sh scripts that ship with the Kafka install.
The
server.tar.gz
release artifact has been deprecated. Users should switch to theOS/architecture-specific server-linux_x64.tar.gz
orserver-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.We are deprecating the
humio/kafka
andhumio/zookeeper
Docker images due to low use. The planned final release for these images will be with LogScale 1.148.0.Better alternatives are available going forward. We recommend the following:
If you still require
humio/kafka
orhumio/zookeeper
for needs that cannot be covered by these alternatives, please contact Support and share your concerns.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 Override garbage collection configuration within the launcher script.
The following GraphQL queries and mutations for interacting with parsers are deprecated and scheduled for removal in version 1.142.
The deprecated createParser mutation is replaced by createParserV2(). The differences between the old and new mutation are:
testData input field is replaced by testCases, which can contain more data than the old tests could. This includes adding assertions to the output of a test. These assertions are not displayed in the UI yet. To emulate the old API, you can take the old test string and put it in the ParserTestEventInput inside the ParserTestCaseInput, and they will behave the same as before.
fieldsToBeRemovedBeforeParsing can now be specified as part of the parser creation.
force field is renamed to allowOverwritingExistingParser.
sourceCode field is renamed to script.
tagFields field is renamed to fieldsToTag.
languageVersion is no longer an enum, but a LanguageVersionInputType instead.
The mutation returns a
Parser
, instead of aParser
wrapped in an object.The mutation fails when a parser has more than 2,000 test cases, or the test input in a single test case exceeds 40,000 characters.
The deprecated removeParser mutation is replaced by deleteParser. The difference between the old and new mutation is:
The mutation returns boolean to represent success or failure, instead of a
Parser
wrapped in an object.The deprecated testParser mutation is replaced by testParserV2(). The differences between the old and new mutation are:
The test cases are now structured types, instead of just being strings. To emulate the old API, take the test string and put it in the
ParserTestEventInput
inside theParserTestCaseInput
, and they will behave the same as before.The new test cases can contain assertions about the contents of the output.
The mutation output is significantly different from before, as it provides more detailed information on how a test case has failed.
The mutation now accepts both a language version and list of fields to be removed before parsing.
The parserScript field is renamed to script.
The tagFields field is renamed to fieldsToTag.
The deprecated updateParser mutation is replaced by updateParserV2() where more extensive test cases can be set. Continuing to use the previous API may result in test information on parsers being lost. To ensure information is not unintentionally erased, please migrate away from the deprecated APIs for both reading and updating parser test cases and use updateParserV2() instead. The differences between the previous and the new mutation are:
testData input field is replaced by testCases, which can contain more data than the old tests could. This includes adding assertions to the output of a test. These assertions are not displayed in the UI yet. To emulate the old API, you can take the old test string and put it in the `ParserTestEventInput` inside the `ParserTestCaseInput`, and they will behave the same as before.
sourceCode field, used to updating the parser script, is changed to the script field, which takes a
UpdateParserScriptInput
object. This updates the parser script and the language version together.tagFields field is renamed to fieldsToTag.
The languageVersion is located inside the
UpdateParserScriptInput
object, and is no longer an enum, but a LanguageVersionInputType instead.The repositoryName and id fields are now correctly marked as mandatory in the schema. Previously this wasn't the case, even though the mutation would fail without them.
The mutation returns a
Parser
, instead of aParser
wrapped in an object.The old mutation had a bug where it would overwrite the languageVersion with a default value in some cases, which is fixed in the new one.
The mutation fails when a parser has more than 2,000 test cases, or the test input in a single test case exceeds 40,000 characters.
On the
Parser
type:
testData field is deprecated and replaced by testCases.
sourceCode field is deprecated and replaced by script.
tagFields field is deprecated and replaced by fieldsToTag.

Upgrades
Changes that may occur or be required during an upgrade.
Other
Bundled JDK upgraded to 22.0.1.
New features and improvements
API
Upgrade to the latest Jakarta Mail API to prevent a warning message from being logged about a missing mail configuration file.
Configuration
When
UNSAFE_RELAX_MULTI_CLUSTER_PROTOCOL_VERSION_CHECK
is set to ensure Multi-Cluster Compatibility Across Versions, attempting to search in clusters older than version 1.131.2 is not allowed and a UI message will now be displayed.
Fixed in this release
Storage
The Did not query segment error spuriously appearing when the cluster performs digest reassignment has now been fixed.
Dashboards and Widgets
Dragging a parameter to an empty Parameter Panel Widget would sometimes not move the parameter. This issue has been fixed.
Functions
The
time:xxx()
functions have been fixed as they did not correctly use the query's timezone as default. The offset was applied in an opposite manner, such that for example GMT+2 was applied as GMT-2. This has now been fixed.
Other
A regression introduced in version 1.132 has been fixed, where a file name starting with
shared/
would be recognized as a shared file instead of a regular file. However, a shared file should be referred to using exactly/shared/
as a prefix.
Improvement
Packages
Validate that there are no duplicate names used for each package template type during package installations (for example you cannot use the same name for multiple parsers that are part of the same package).
