Appliance

OpenNMS Appliance is a way to reliably and securely collect network monitoring data from hard-to-access areas of your infrastructure.

Appliances can be physical hardware or virtual machines—whatever works best within your infrastructure environment.

OpenNMS Appliance in mini form factor

Cloud-enabled distributed monitoring

OpenNMS Appliance lets you easily deploy and manage Minions, lightweight services that enable OpenNMS to communicate with devices and services on your network. Minions, deployed "raw," can be difficult to update and configure without workarounds or homebrew scripts.

Our cloud-hosted Appliance service helps you:

  • Configure your entire fleet of Appliances—and Minions—in one action.
  • Define groups of Appliances and apply batch configurations to specific groups, as needed.
  • Schedule or automate updates for your Appliances—ensuring they have the latest bug and security fixes.
  • Keep your fleet of Minions within Appliances in sync with the core OpenNMS platform. This guarantees monitoring data continuity through updates.

Better together: Appliance & Minion

Minions are the "eyes and ears" of OpenNMS. Rather than directly polling locations and devices from the core system, users can deploy Minions to extend the monitoring capabilities of OpenNMS to remote locations or behind private networks. By relying on Minions, you get:

  • Greater security. Minions send all monitoring traffic through a single port, rather than maintaining a large set of firewall rules for multiple monitoring protocols. You can operate Minions behind firewalls or a NAT, lowering your attack surface. The Minion helps isolate network communications away from the core, which has direct access to sensitive data and systems.
  • IP overlap, made possible. Meridian and Minion, together, help operations monitor networks with overlapping IP spaces. Minions and monitored nodes can be associated with locations defined in Meridian.
  • Monitoring continuity: Minions cache and persist the message broker queue to help prevent data loss in the event of connectivity issues.

The Appliance, applied

An OpenNMS Appliance is essentially a "Minion in a box"—easily deployable, configurable, and updatable. Appliances can be deployed virtually—as a VMware-based virtual environment—or as physical hardware.

The Appliance is available now1 in a mini form factor, with a 1U rack unit coming soon.

Features & benefits

Zero-trust architecture

The Appliance is designed for security and features a Trusted Platform Module (TPM), secure boot, and disk encryption to help prevent tampering and backdoors as part of our greater zero-trust initiative.

Deployment and management, simplified

Appliances can be installed and configured, through our cloud portal in minutes. And Minions running on Appliances can be managed in groups—or as an entire fleet—in a single action, saving you time and engineering resources.

Automatic and scheduled updates

Never miss an update. Regular 5-minute checks ensure the Minion version matches the Meridian core and updates automatically. Customized policies ensure consistency across multiple Appliances.
