Network Mapping Software and Mapper Tool - ManageEngine OpManager

1 Million and Counting

What is network mapping?

Network mapping is a process used to discover new devices, interfaces and visualize physical and virtual network connectivity. Map your network with confidence and stay in control as OpManager helps you discover, and optimize every connection.

Network mapping with OpManager: A quick walkthrough

Discovery Visualization Topology Dependencies Maps Alerts Reports

Discovery

OpManager automatically discovers devices across your network using protocols like SNMP, ICMP, and WMI.
Whether it’s a small branch setup or a complex data center environment, discovery is the first step toward complete visibility. Devices are identified, classified, and organized- ready to be visualized.

Visualization

Each discovered device is plotted onto dynamic, interactive maps that reflect real-world connectivity.
OpManager visualizes routers, switches, servers, and interfaces as graphical nodes, allowing you to navigate between layers and view live performance metrics from a single pane.

Topology

Layer2 maps automatically represent the physical topology of your network, showing exactly how switches, routers, and endpoints interconnect.
The auto-refreshing topology view eliminates manual documentation and ensures your visual map always matches the current network state.

Topology

Dependencies

Beyond connections, OpManager identifies logical dependencies- showing which services rely on specific devices or interfaces.
This relationship mapping is crucial for root cause analysis; when an outage occurs, admins can instantly trace the dependency chain to isolate the true source.

Maps

Custom maps let you model your network the way you see it. Create business or geographical maps for branches, departments, or data centers.
Drag-and-drop visual editing, background floor plans, and color-coded device statuses make it easy to manage network sprawl visually.

Maps

Alerts

With topology-aware alerting, OpManager correlates faults with the affected segments on the map.
When a device goes down, its dependent devices are automatically suppressed from triggering redundant alarms- helping admins focus on the real fault instead of alert noise.

Reports

Mapping insights are actionable when backed by data. OpManager generates reports on network structure, discovered devices, and topology changes.
These reports help verify compliance, capacity planning, and infrastructure growth over time.

Managing network visibility with OpManager

Constant topology synchronization

OpManager automatically keeps your topology maps in sync with real-time network changes. As devices are added, removed, or reconfigured, the maps update instantly- ensuring admins never rely on outdated diagrams.
This continuous sync helps maintain accurate visibility during expansions or maintenance cycles.

Accelerated root cause analysis

Topology-aware fault correlation pinpoints the true source of network outages. When a router or switch fails, OpManager suppresses dependent alerts and highlights the affected path visually on the map.
This shortens troubleshooting time, prevents redundant alarms, and accelerates mean time to repair (MTTR).

Compliance and audit readiness

Network maps double as compliance artifacts. With historical topology reports and configuration versioning, OpManager helps admins verify connectivity, identify unauthorized changes, and maintain audit trails of how network layouts evolved over time. This simplifies both internal reviews and external audits.

OpManager's extensive mapping suite works together with its incident detection and remediation capabilities

Topology-aware fault correlation

OpManager’s network mapping engine isn’t just visual- it’s intelligent. By understanding device interdependencies, it correlates alarms with topology data to isolate the true root cause. When a core router fails, dependent switches and endpoints are automatically marked as impacted rather than triggering redundant alerts. This reduces alert noise and helps admins focus on the originating fault instantly.

Automated response through workflows

With OpManager’s drag-and-drop workflow automation, IT teams can design rule-based actions that respond to network incidents without manual intervention. For example, a workflow can be triggered when a device goes down- automatically pinging the dependent nodes, restarting an interface, or updating the topology map. This closed-loop automation minimizes downtime and standardizes first-level remediation.

Root cause visualization

Root cause analysis is simplified when topology and performance data coexist. OpManager allows admins to open relevant performance graphs for affected devices side by side within the same visual map. This makes it easier to correlate bandwidth spikes, interface errors, or configuration changes with the device that triggered the event.

Seamless ITSM integration

Network incidents can be instantly escalated through OpManager’s ITSM integrations with ServiceDesk Plus, ServiceNow, Freshservice, and Jira. When an alert is raised, it can be auto-converted into a ticket containing contextual data- including topology position, dependency impact, and historical performance- so IT teams can collaborate effectively and maintain up-to-date CMDB entries.

Benefits of comprehensive network mapping with OpManager

Scalable network visualization for any environment

From small office setups to complex, multi-site enterprise networks, OpManager’s network mapping adapts seamlessly. It can automatically discover and visualize thousands of devices across LANs, WANs, and hybrid infrastructures, maintaining accuracy even as your network grows or restructures.

Always up-to-date and topology-aware

Unlike static diagrams, OpManager’s maps auto-refresh whenever devices, interfaces, or configurations change. This ensures topology accuracy at all times- eliminating manual updates, broken links, or outdated documentation that often lead to troubleshooting errors.

Unified view of your entire network ecosystem

OpManager consolidates routers, switches, firewalls, and servers into interactive maps that reveal physical and logical connectivity. You can zoom in to inspect an individual device or zoom out for a macro view of your global network—all from a single console.

Faster fault isolation and response

With topology-aware alerting and dependency mapping, OpManager helps admins identify the true root cause of outages in seconds. When a core device fails, its dependent systems are visually flagged, reducing mean time to detect (MTTD) and repair (MTTR).

Automated discovery and map generation

OpManager removes manual effort from network documentation through scheduled discovery and dynamic map generation. IT teams save hours of routine mapping work while ensuring visual accuracy, freeing them to focus on proactive maintenance and optimization.

Lower operational overhead, higher ROI

By combining discovery, visualization, fault correlation, and reporting in one unified platform, OpManager eliminates the need for separate topology tools or manual mapping software. This integrated approach reduces tool sprawl and offers long-term savings on both time and licensing.
