Release 2023.1.4 contains one CVE-related security fix, a generous helping of other bug fixes, and several small enhancements intended to improve supportability.

The codename for Meridian 2023.1.4 is Zoot.

Breaking changes

  • This release has moved to a newer major version of Spring Security to address a number of CVEs, which necessitated changes to the $OPENNMS_HOME/jetty-webapps/opennms/WEB-INF/applicationContext-spring-security.xml file, so if you have modified this file in your installs, be sure to note your changes so you can reapply them to the updated version.

  • The script $OPENNMS_HOME/bin/install checked whether $myser equals $RUNAS before sourcing $OPENNMS_HOME/etc/opennms.conf, which caused startup to fail every time unless the script were run as root; if you have patched that file on your system, watch out for a .rpmsave or .dpkg-new file.

This new major-version release introduces several breaking changes (see below).

Breaking Changes

  • The GpDetector and ScriptPolicy now require that their scripts be located beneath $OPENNMS_HOME and beneath $OPENNMS_HOME/etc/script-policies, respectively. If you are using either of these classes in your foreign-source definitions, please address this requirement before upgrading to this release.

  • The OpenNMS Plugin API (OPA) has been updated to 1.3.0. OPA plugins intended to run in Meridian 2023.1.0 must implement version 1.0.0 or higher.

  • The provisiond-configuration.xml file has been replaced with a new implementation based on the new configuration management API, which resides outside the filesystem. See What’s New in Meridian 2023 for more information.

  • Meridian Docker images are now based on a minimal install of Ubuntu, rather than CentOS. Symlinks are provided to match the old paths in /opt, but it’s possible you will run into subtle differences when transitioning.

  • The org.opennms.netmgt.collectd.strictInterval setting now defaults to true. See What’s New in Meridian 2023 for more information.

Known issues

The following known issues impact Meridian 2023.1.0; we expect all to be fixed in the next micro-version release:

  • Regular users are unable to acknowledge or clear alarms from the geographical map’s integrated alarm browser. Until we identify a fix, it is possible to work around this problem by adding ROLE_REST to a user’s set of assigned roles. See NMS-15080 for details. Thanks to Ricardo Monteiro for bringing this problem to our attention.

  • On systems where dual-write time series persisting is enabled, an intermittent startup problem may cause either a delay in data starting to be persisted, or a hard failure necessitating a restarting of the core. See NMS-15326 for details.

  • The ALEC plugin currently cannot be successfully installed on a Sentinel node. At release time, it is unclear whether the problem lies in Sentinel or in ALEC. Some details are captured in NMS-15396.


The codename for Meridian 2023.1.0 is Kermit the Frog.
