Why IoT device monitoring fails without network visibility
Every unseen device is unmanaged risk. IoT projects add hundreds of sensors, gateways, cameras, and controllers to networks that were never sized for them. Without IoT device monitoring across the whole network, faults surface as complaints instead of alerts, and compliance evidence turns into guesswork.
NMIS gives you one place to discover, monitor, and manage every connected device. Network visibility becomes something you can show an auditor, not something you assume.
Discover and monitor every IoT device with NMIS
NMIS has monitored production networks since 1998. It adapts readily to IoT environments, whether devices speak SNMP directly or report through a cloud application API.
Network discovery. NMIS finds and maps IoT devices automatically. No manual inventory, no spreadsheet of forgotten hardware. Every device on the network is accounted for.
Configuration management. Track configuration changes from a centralised repository, enforce compliance, and restore a known-good state quickly when something drifts.
Real-time monitoring. NMIS captures performance data such as bandwidth, latency, and device responsiveness across connected fleets. Anomalies show up as they happen, not at the next manual check.
Event correlation. Paired with opEvents, event streams from IoT devices are correlated and deduplicated, cutting alert noise so your team acts on what matters.
What centralised IoT monitoring delivers
Better device performance
See utilisation and response trends per device, spot bottlenecks, and fix them before users notice.
Predictive maintenance
Performance history shows which devices are trending towards failure, so you schedule work instead of reacting to outages.
Scale without losing oversight
Add devices as the deployment grows. Centralised monitoring keeps one view of the whole network.
Lower running costs
Usage and consumption metrics show which devices are overprovisioned, underused, or due for retirement.
Compliance and resilience
Evidence device state and configuration history on demand. Unusual device behaviour is flagged early, and recovery is a restore, not a rebuild.
Decisions backed by data
Accurate, current device data supports capacity planning, budgeting, and service decisions.

Dashboards, reports, and alerts your team will actually use
Customisable dashboards. opCharts builds monitoring views around your devices, sites, and services, so each team sees the data it needs.
Scheduled reporting. opReports turns monitoring data into scheduled reports for operations, management, and audits.
Proactive alerting. Real-time notifications reach your team when a critical event or performance anomaly occurs, so incidents are handled before they spread.
Works with what you have. NMIS supports a wide range of connected devices, protocols, and technologies. Keep your current investment and monitor it properly.

Frequently asked questions
What types of IoT devices can NMIS monitor?
Any device that responds over SNMP (v1, v2c, or v3) can be monitored directly, including sensors, gateways, cameras, controllers, and the network gear connecting them. Devices that only report to a cloud application can be monitored through that application's API.
Does NMIS need an agent on each IoT device?
No. NMIS polls devices over the network, so there is nothing to install on the devices themselves.
How does NMIS handle devices that only report through a cloud API?
NMIS ingests device data from cloud application APIs, so devices without a direct network management interface still appear alongside the rest of your inventory.
How many devices can one NMIS deployment monitor?
NMIS scales horizontally. opHA distributes polling across multiple servers with a single consolidated view, so device count grows with your deployment rather than capping it.
