UI for Role Based Access Control (RBAC), Health Check API, Kafka Version Update, Vega Charts

Fixed in this release

  • Summary

    • Now, you can click Edit Styling in the widget menu and modify styling directly from the dashboard view.

    • Improved (reduced) memory consumption for live groupby, and for groupby involving many distinct keys.

    • Since charts are such a central feature, we allow disabling the new implementation of widgets if you are experiencing issues with them. You can disable Vega charts globally using the ENABLE_VEGA_CHARTS=false flag.

    • This version replaces our chart library with Vega. The goal is to create a better, customizable, and more interactive charting experience in Humio. This first iteration is largely just a feature replacement for the existing functionality, with a few exceptions

    • You can now style your pie charts, and they will default to having a center radius (actually making them donuts!).

    • You can now style your bar charts to control things like label position and colors.

    • Queries involving join can now be with 'used export to file' and the /query HTTP endpoint.

    • Role Based Access Control (RBAC) through the UI is now the only permission model in Humio. Please see the Manage users & permissions documentation for more information.

    • To prevent the charts from getting cluttered, you can adjust the maximum number of series that should be shown in the chart. Any series that are not part of the top-most series will be summed together and added to a new series called Other.

    • Be aware that updating Kafka also requires you to update ZooKeeper to 3.5.6. There is a migration involved in updating ZooKeeper. See the ZooKeeper migration FAQ here. Use the migration approach using an empty snapshot. The other proposed solution can loose data.

    • Humio's NetFlow support has been extended to also support IPFIX. See Humio's documentation for NetFlow Log Format.

    • Each chart type now supports assigning colors to specific series. This will allow you to, for instance, assign red to errors and green to non-errors.

    • Updated Kafka and ZooKeeper Docker images to use Kafka 2.4. Updating to Kafka 2.4 should be straightforward using Humio's Kafka/ZooKeeper Docker images. ZooKeeper image will handle migration. Stop all Kafka nodes. Stop all ZooKeeper nodes. Start all ZooKeeper nodes on the new version. Start all Kafka nodes on the new version. Before updating Kafka/ZooKeeper, we recommend backing up the ZooKeeper data directory. Then, add the ZooKeeper properties described below. If you are deploying Kafka/ZooKeeper using other tools, for example Ansible scripts, be aware there is a migration involved in updating ZooKeeper.

    • Linear interpolation is now the default, and we have added a new type of interpolation: Basis.

    • When updating Kafka/ZooKeeper we recommend setting these ZooKeeper properties

      • Do not start the new admin server. Default port 8080 conflicts with Humio port.admin.enableServer=false

      • purge old snapshot files autopurge.purgeInterval=1

      • Allow 4 letter commands. Used by Humio to get info about the ZooKeeper cluster 4lw.commands.whitelist=*

    • You can find the series configuration controls in the Style tab of the Search page.

    • The overall health of a Humio system is determined by a set of individual health checks. For more information about individual checks see the Health Checks page and the Health Check API page.

    • Updated Humio to use Kafka 2.4. Humio can still use versions of Kafka down through 1.1.
