New: Meridian 2021

Distributed environment, distributed monitoring, central visibility

More distributed monitoring. More flows. More configurability. OpenNMS Meridian 2021 gives you more of everything you expect from an open-source network monitoring platform that already does so much.

Meridian now features Application Perspective Monitoring (APM), which monitors location-specific conditions from other locations. Pinpoint not only where an issue occurs, but its impact on a user’s (or machine’s) digital experience.

Enhanced customization means Meridian 2021 can be as unique as your network and the organization it supports. Adapt Meridian to meet your needs, instead of adapting your needs to fit your NMS.

Collect and persist flows from more sources with an optimized and expanded BGP Monitoring implementation.

Extend the reach of your network monitoring with Meridian 2021.

Full Release Notes

Meridian Data Sheet

New to Meridian 2021

Monitor Digital Experience From Different Perspectives

A key part of OpenNMS’ distributed monitoring solution, Application Perspective Monitoring (APM) monitors the digital experience (DEM) of services and application systems from different perspectives such as geographical locations (countries, regions, buildings) or a cloud application from the client’s viewpoint.

APM integrates seamlessly with our remote monitoring Minion component. When a service is not responsive, OpenNMS generates an outage alert that includes the corresponding perspective that identified the outage.

If the New York operations center can see the availability of a service hosted in Houston that is accessed by users in Seattle, you can identify the perspective from which an outage occurs for more effective troubleshooting and network reliability.

Enhanced Customization

Adaptability has always been one of Meridian’s strengths. Meridian 2021 adds even more opportunities to customize it:

  • Additional remote monitoring configuration options when using Docker to run Minion: setting Jetty, RMI, and SSH host and port, Secure Credentials Vault configuration, and environment variables and options for the JVM
  • Custom OpenNMS Sentinel system properties make scalability configuration for data processing easier to maintain
  • Data collection configuration for Netscaler vServer
  • New or updated Karaf shell commands for improved performance
  • REST API improvements around events and retrieving application status

Improved BGP Monitoring

Support for the BGP Monitoring Protocol (BMP) in the streaming telemetry feature (telemetryd) just got better with enhanced route updates from external resources like autonomous system number (ASN), Whois, and Resource Public Key Infrastructure (RPKI). OpenNMS persists basic BMP messages from routing devices to TimescaleDB, so you can query them from Grafana for dashboard display.

Originally implemented with OpenBMP, we have created an optimized, more maintainable BGP monitoring implementation that coexists with the original.

Use Metadata in More Places

Leverage dynamic configuration to use metadata with provisioning, threshold evaluation, and notifications:

  • Provisioning: persist node, service, and interface metadata to the database during provisioning
  • Threshold evaluation: streamline threshold creation for single-DS and expression-based thresholds
  • Notifications: use node-, interface-, and service-level metadata in notifications

Easier Access to the Information You Need

Meridian 2021 debuts our new documentation, migrated to the Antora platform, and our new branding. View documentation for all components and plugins in one place, with top-level links to additional help through training videos and community tools like Discourse and Mattermost. New search functionality allows you to easily find the answers you need.

And speaking of search, the Web UI’s new universal search bar helps you quickly locate specific alarms, nodes, interfaces, and more from the top of any page in the UI.

RPC, Telemetry, Flows, and BMP Improvements

Collect more metrics and improve performance with:

  • Support for aggregate flow metrics
  • Aggregate flow queries that support resolving hostnames, if available
  • Better flow DNS enrichment
  • Enhanced sink RPC APIs that expose metrics to Karaf for tracing and performance tuning
  • A new telemetry adapter to collect metrics via OpenConfig over the gRPC Juniper Telemetry Interface (JTI) and gNMI

Better Encryption for Polling and Monitoring

Updated support for WMI/SMB with a wider set of encryption types available for use.
