Horizon 33: OpenShift support and a better way to view nodes

We’ve continued our Helm Chart compatibility effort by adding support for the RedHat OpenShift containerized environment, delivering greater flexibility in the Horizon install and upgrade process. We’ve also upgraded our node list to enable data search, filter, sort and export to deliver a custom view of nodes of interest.

New in Horizon 33: February 14, 2024

Helm charts improvements and OpenShift compatibility

We’ve improved our Helm charts for Kubernetes featured in Horizon 32 and made them compatible with OpenShift to simplify the deployment process further. Rather than needing to provision a virtual machine or physical system, users can run the Helm chart to deploy the software to a Kubernetes or OpenShift environment in a highly scalable, easily upgradable process.

Structured node list

Our user experience team has developed a modern, easier-to-use display for browsing and reviewing your monitored node inventory. The updated, structured list lets users perform enhanced data display, search, filter, and export.

The main display shows a paginated table of nodes corresponding to the current search and filtering parameters. You can sort most of the columns in ascending or descending order.

You can choose from 10, 20, or 50 entries per page, navigate among pages, or go to the start or end of the currently filtered set.

Other changes and improvements
