What is router monitoring?

Router monitoring is the process of monitoring a router's health, availability, and performance. Router monitoring software uses protocols like SNMP, ICMP, gNMI, and flow technologies to monitor your routers. ManageEngine OpManager is a network monitoring software with powerful router monitoring capabilities. OpManager's vendor-agnostic router support and AI-driven monitoring helps you find router issues before they affect the users.

OpManager's router monitoring capabilities

Track router availability and key performance indicators

OpManager pings your routers on a regular basis with protocols like SNMP, ICMP, TCP, and gNMI to monitor their uptime and performance.

Review your router uptime statistics with timelines, graphs, auto-generated reports, and dashboards.
Track key metrics like the CPU utilization, memory usage, traffic statistics, and buffers.
Leverage dedicated maps, reports, and graphs to analyze router performance.

Speed up MTTD and MTTR with instant, context-rich alarms

Get colour-coded alarms with added context about the severity of the issue to aid troubleshooting.

OpManager identifies network-level dependencies and suppresses alarms. So, if your core router goes down, you get one alarm instead a flood of alarms about the dependent devices going down.
OpManager's AI-driven adaptive thresholds set and update performance monitoring alarms automatically, on an hourly-basis.
Ensure that you're aware of all router issues by setting up notifications through SMS, email, helpdesk tickets, third-party chat tools, and more.

Ensure optimal router health with regular hardware checks

Monitor the health status of your router's hardware components to prevent unplanned network outages.

Leverage specialized reports to keep tabs on interface traffic and utilization.
Set up interface discovery rules to fine tune the interfaces that are automatically added for monitoring.

Monitoring WAN links

Discover and add WAN up links connected to your edge routers, classify them based on their sites and ISP providers, and track their uptime status.

Configure ISP SLA parameters to monitor WAN round trip time (WAN RTT) and availability to get instant alerts for SLA violations.
Track the latency and response time for each hop in a WAN link using network path analysis profiles.

Traffic and config management

OpManager's NeFlow analyzer add-on helps you get in-depth visibility into traffic usage from your routers at the interface, user, and app level with flow technologies like: NetFlow, sFlow, IPFIX, Netstream, J-Flow, and AppFlow.

OpManager's Network Configuration Manager add-ons gives you complete control over your network configurations and changes at the router level to ensure business continuity and compliance.

How to perform router monitoring with OpManager

Discovering routers

OpManager automatically scans your network to discover routers using protocols like SNMP, ICMP, Telnet, and SSH. Once found, devices are automatically classified by vendor and model, and mapped to a curated set of performance monitors.

Monitoring router performance

OpManager supports thousands of out-of-the-box performance monitors for top vendors like Cisco, Juniper, Aruba, Huawei, and HPE. By leveraging adaptive thresholds, you can automatically set and update performance alarms across thousands of routers simultaneously.

Alarms and notifications

OpManager generates contextual alarms the moment a router's performance deviates from the expected baselines. You can configure instant notifications through multiple channels, including email, SMS, third-party collaboration tools like Slack, or as tickets in your helpdesk software.

Capacity planning

OpManager uses built-in AIOps capabilities to streamline capacity planning and resource sizing. By analyzing historical performance data, the system predicts exactly when critical router resources: such as CPU, memory, or traffic utilization, will reach their upper limits.

What are the benefits of performing router monitoring with OpManager?

Multi-vendor support & scalability

OpManager supports top router vendors like Cisco, Huawei, Aruba, and Juniper. Discovery and classification is automated, you can scale to 50,000 devices, and monitor distributed network sites. This makes OpManager one of the most versatile router monitoring software.

Network and router mapping

OpManager combines router monitoring with in-depth network mapping. You can discover the interfaces and devices connected to your seed/edge routers and draw automatically updating layer2 maps. They help identify device dependencies, link outages, and network topology.

Faster root cause analysis

When outages occur, quick resolution is critical. OpManager uses AI and ML to automatically correlate events and pinpoint potential root causes. Additionally, network path analysis profiles simplify troubleshooting by visually isolating the exact node where the fault occurred.

Optimized bandwidth and WAN

By analyzing traffic patterns, link utilization, and throughput, organizations can identify underused links and reallocate capacity where needed. This not only enhances performance but also reduces unnecessary WAN expenditure, ensuring every Mbps delivers maximum value.

FAQs on router monitoring

OpManager supports SNMP (v1/v2c/v3), ICMP, CLI (Telnet/SSH), WMI and flow protocols like NetFlow/sFlow/jFlow/IPFIX. OpManager also supports gRPC Network Management Interface, or gNMI to provide more granular network telemetry.

Essential metrics go beyond basic uptime to include internal CPU and memory utilization, device temperature, cooling fan speeds, and power supply stability. At the data link layer, tracking packet errors, buffer misses, speed collisions, and Cyclic Redundancy Check (CRC) errors is vital. Monitoring these physical and logical parameters simultaneously allows IT teams to identify subtle performance issues early, scheduling targeted hardware maintenance or resource upgrades before users experience an operational outage.

Yes. OpManager tracks link availability, latency, packet loss and hop-by-hop performance through routers and identifies whether issues are internal or via the ISP.

Basic router tracking only shows if an interface is busy, but integrating flow-based technologies like NetFlow, sFlow, J-Flow, or IPFIX provides the granular detail needed for root-cause analysis. Flow analysis drills directly down to the interface, individual user, and application level. This allows you to pinpoint the exact device or software: such as unauthorized video streaming or massive file transfers, causing network congestion, helping you optimize traffic distribution without purchasing expensive bandwidth upgrades.

You can resolve this by grouping edge routers based on site and provider to monitor WAN Round Trip Time (RTT) and overall link availability. By configuring specific IP Service Level Agreement (SLA) parameters within your monitoring suite, the software constantly measures connection latency and packet delivery. The moment performance drops below your contractual agreement, the system flags the SLA violation, providing the verifiable historical reports needed to address service drops with your provider.

Network path analysis provides a visual, hop-by-hop map of the exact route data packets travel from source to destination. By analyzing each node along the WAN link, the tool isolates the precise physical device, internal hop, or external ISP link where high latency or packet loss is occurring. This deep visual tracking eliminates the traditional blame game between internal teams and external providers, drastically reducing the time it takes to resolve branch-to-cloud performance bottlenecks.

Modern AIOps platforms use advanced machine learning algorithms to evaluate months of historical utilization data across CPU, memory, and interface bandwidth. Instead of relying on manual calculations, the AI accurately forecasts the exact number of days left before a router's physical capacity hits critical thresholds like 80, 90, or 100 percent. This predictive insight enables data-driven resource sizing and procurement planning, ensuring long-term network resilience as enterprise traffic grows.
