ZenPlus knowledge base
ZenPlus documentation
Setup, integration, and operations guides for the ZenPlus on-premises monitoring platform and its OTA update system — from the one-line installer to running a registered fleet in production.
Getting started
First steps with ZenPlus
Start with the installation guide, then learn how appliances stay current and how per-device (per-IP) licensing works.
Installation Guide
Install the appliance on Ubuntu with one command: requirements, the 16 verified installer steps, the automatic 30-day trial, enabling HTTPS, verification, day-two operations, and troubleshooting.
Read articleOTA Update Flow
How appliances check in every 4 hours, download .zup packages, and report update status back to the platform.
Application Monitoring (APM)
The full APM documentation set: OpenTelemetry ingest, golden signals, service map, distributed traces, error tracking, SLO burn alerts, synthetic journeys and troubleshooting.
Read the APM docsUser Device Tracker (UDT)
Track every endpoint on the network: which MAC, IP, user, switch and port. SNMP layer-2 collection, switch port capacity, device classification, rogue detection and Active Directory user correlation.
Read the UDT docsPer-device licensing
ZenPlus is licensed per unique IP, billed annually, with unlimited interfaces on each device. Live list prices and volume discounts are on the pricing page — there are no unpublished 10/50/100 node bundles.

Running ZenPlus in production
Day-two guides for the teams that keep a registered ZenPlus fleet monitored, healthy, and compliant.
Instrumenting Applications
Create an ingest key, point an OpenTelemetry SDK at the appliance, and verify the first span arrives — the fastest path from an empty APM module to live golden signals.
Read articleSwitch & Active Directory Permissions
The exact SNMP objects UDT reads, the vlan- context grant Cisco IOS requires before it will return a MAC table, and the read-only Windows rights needed for agentless user correlation.
UDT Troubleshooting
Symptom-first fixes for layer-2 collection: a switch that returns no endpoints, endpoints with no port, everything showing as indirect, unknown vendors and missing user logins.
Read articleSecurity & Compliance
Key rotation, API key revocation, and audit log access for environments with strict governance requirements.
