Important Information about Upgrading

Beginning with version 1.17.0, if your current version of Humio is not directly able to upgrade to the new version, you will get an error if you attempt to start up the incompatible version. The 1.23.0 release is only compatible with Humio release 1.16.0 and newer. This means that you will have to ensure that you have upgraded at least to 1.16.0 before trying to upgrade to 1.23.0. In case you need to do a rollback, this can also ONLY happen back to 1.16.0 or newer. Rolling directly back to an earlier release can result in data loss.

Humio will make some internal logs available in a new repository called humio-activity. This is meant for logs that are relevant to users of Humio, as compared to logs that are only relevant for operators. The latter logs are still put into the humio repository. For this release, only new log events will be put into humio-activity, but in later releases, some existing log events that are relevant for users, will be put into the humio-activity repository instead of the humio repository.

For cloud users, the logs for your organization can be accessed through the humio-organization-activity view.

For on-prem users, the logs can be accessed directly through the humio-activity repository. They are also output into a new log file named humio-activity.log which can be ingested into the humio repository, if you want it available there as well. If you do and you are using the Humio Insights Application, you should upgrade that to version 0.0.4. For more information, see Internal Logging documentation.

Humio has decided to adopt an evolutionary approach to its GraphQL API, meaning that we will strive to do only backwards compatible changes. Instead of making non-backwards compatible changes to existing fields, we will instead add new fields alongside the existing fields. The existing fields will be deprecated and might be removed in some later release. We reserve the right to still do non-backwards compatible changes, for instance to fix security issues.

For new experimental features, we will mark the corresponding GraphQL fields as PREVIEW. There will be no guarantees on backwards compatibility on fields marked as PREVIEW.

Deprecated and preview fields and enum values will be marked as such in the GraphQL schema and will be shown as deprecated or preview in the API Explorer. Apart from that, the result of running a GraphQL query using a deprecated or preview field will contain a new field extensions, which contains a field deprecated with a list of all deprecated fields used in the query and a field preview with a list of all preview fields used in the query.


 "data": ...
 "extensions": {
 "deprecated": [
 "name": "alert",
 "reason": "[DEPRECATED: Since 2020-11-26. Deprecated since 1.19.0. Will be removed March 2021. Use 'searchDomain.alert' instead]"

Deprecated fields and enum values will also be noted in the release note, when they are first deprecated. All use of deprecated fields and enum values will also be logged in the Humio repository humio-activity. They will have #category=GraphQL, subCategory=Deprecation and #severity=Warning. If you are using the API, consider creating an alert for such logs.

Removed Support for CIDR Shorthand

Previous version of Humio supported a shorthand for IPv4 CIDR expressions. For example 127.1/16 would be equivalent to This was contrary to other implementations like the Linux function inet_aton, where 127.1 expands to Support for this shorthand has been removed and the complete address must now be written instead.

Bug Fixes

  • Other

    • Fixed an issue with the Missing Segments API that caused missing segments to not appear in the missing segments list if they had a replacement segment.

    • Fixed an issue where changes to files would not propagate to parsers or event forwarders.

    • Fixed an issue where Prometheus metrics always reported 0.0 for humio_primary_disk_usage

    • Changed the URL of the Kafka cluster page in the settings.

    • Fixed the requirement condition for the time retention on a repository.

    • Added IP Filter for readonly dashboard links, and started to audit log readonly dashboard access. In this initial version. The readonly ip filter can be configured with the graphql mutation:

      mutation {
       updateReadonlyDashboardIPFilter(ipFilter: "FILTER")

      The FILTER is expected in this format: IP Filter. From Humio 1.25 this can be configured in the configuration UI.

    • Fixed an issue which caused ingest-to-multiple-repos to break, when the parser used copyEvent to duplicate the input events into multiple repositories

    • Fixed an issue causing undersized segment merging to repeatedly fetch the same segments, in cases where the merger job took too long to finish.

    • Added an option to make it easier to diagnose problems by detecting inconsistencies between globals in different Humio instances. Each Humio instance has its own copy of the global state which must all be identical. It has happened that they were not, so now we check and if there is a difference we report an error and dump the global state into a file.

    • Made the S3 archiving save button work again.

    • Enforce permissions to enter creating new repository page.

    • Fixes a bug where events deleted with the delete-event API would appear deleted at first, but then resurface again after 24h. If user applying delete did not have permission to search the events being deleted.

    • Allow turning encryption of files stored in bucket storage off by explicitly setting S3_STORAGE_ENCRYPTION_KEY=off (similar for GCP_ )

    • The GraphQL API Explorer is now available from inside Humio. You can access it using the Help->API Explorer menu.

    • Restyled the alert dialogue.

    • Fixed a bug where the same regex pattern occurring multiple times in a query could cause incorrect results

    • Added support for CIDR matching on match() using mode=cidr.

    • Added GraphQL queries and mutations for alerts and actions, which correspond to the deprecated REST endpoints for those entities.

    • Negated, non-strict match() or lookup() is no longer allowed.

    • Added a new introduction message to empty repositories.

    • Improved memory use for certain numerical aggregrating functions

    • Enforce permissions to enter Organization Settings page.

    • Fixed an issue where regular expressions too large to handle would sometimes cause the query to hang. Now we report an error.

    • Refactor how the width of the repository name in the main navigation bar is calculated.

    • Enforce accepting terms and conditions.

    • Deprecated GraphQL mutations addAlertLabel, removeAlertLabel, addStarToAlert and removeStarFromAlert as they did not follow the standard for mutation input.

    • Mark required fields on the Accept Terms and Conditions page.

    • Added mode parameter to match(), allowing different ways to match the key.

    • Refactor All Organizations page.

    • Deprecated the ReadEvents enum variant from the ViewAction enum in GraphQL. Use the ReadContents variant instead, which has the same semantics, but a more accurate name. ReadEvents will be removed in a future release.

    • Deprecated file and column parameter on cidr(). Use match() with mode=cidr instead.

    • Deprecated glob parameter on match(), use mode=glob instead.

    • Fixed a bug which caused glob-patterns in match() to not match newline characters

    • The SearchDomain.queries GraphQL field has been deprecated, and will be removed in a future release. Use SearchDomain.savedQueries instead.

    • The GraphQL API Explorer has been upgraded to a newer version. The new version includes a history of the queries that have been run.

    • Implemented toggle button for dark mode.

    • The SearchDomain.viewerCanChangeConnections GraphQL field has been deprecated, and will be removed in a future release. Use SearchDomain.isActionAllowed instead.

    • Removed support for shorthand IPv4 CIDR notation in cidr(). See section "Removed support for CIDR shorthand".

    • Improved performance when using match() with mode=cidr compared to using cidr() with file().

    • UI enhancements for the new repository Access Permissions page.

    • It is again possible to sort the events on the test parser page.

    • Improved performance of free-text search using regular expressions

    • Deprecated the REST endpoints for alerts and actions.

    • Fixed a bug which caused in() with values=[] to give incorrect results

    • Refactor client side action cache of allowed permissions.

    • Fixed a bug which caused tag-filters in anonymous functions to not work in certain cases (causing to many events to be let through)

    • Fixed a bug which caused match() to give incorrect results in certain cases due to incorrect caching

    • Removed the deprecated Repository.isFreemium GraphQL field.

    • Added GraphQL mutations addAlertLabelV2, removeAlertLabelV2, addStarToAlertV2 and removeStarFromAlertV2.

    • Refactor Organization Overview page.

    • Fixed a bug in event forwarding that made start(), end() and now() return the time at which the event forwarding rule was cached. Instead, now() will return the time at which the event forwarding rule was run. start() and end() were never meant to be used in an event forwarding rule and will return 0, which means Unix Epoch.
