  • PostgreSQL 10 or higher: Meridian 2024 requires any supported version of PostgreSQL from 10 up to (and including) 15.

New features and improvements

Structured Node List

The structured node list organizes the nodes in an easier to navigate way. The user can search, filter and export data.

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

Extended Meta Data Support

Key-value pair based meta data can now be added to almost every entity within OpenNMS. You can now annotate with metadata threshold fields, poller parameters, and integrations (WSMAN, JCIFS, IFTTT, VMware).

Security Improvements

  • Users must now change the Administrator password on first login.

Helm Charts and OpenShift

Meridian can now be deployed on containerized environments. This will result in easier updates and upgrades.
