What is switch monitoring?

Switch monitoring is the practice of tracking the health and connectivity of network switches. As businesses scale and embrace hybrid work, switches handle more load. This means that switch issues can have far-reaching effects. ManageEngine OpManager is a network monitoring software with powerful switch monitoring capabilities. With OpManager, IT teams can detect switch issues proactively and prevent unplanned outages.

How to perform switch monitoring with OpManager

Discovering switches

OpManager automatically scans your network to discover switches using protocols like SNMP and ICMP. OpManager supports stack and PoE-type switches. Once found, the switches are automatically classified by vendor and model. They are also assigned a set of performance monitors.

Monitoring switch performance

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

Alarms and notifications

OpManager generates contextual alarms the moment your switch 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 switch resources like CPU or memory reach their upper limits.

FAQs on switch monitoring


Switch monitoring is the continuous tracking of network switch health, performance, and traffic to ensure reliable network connectivity. It enables administrators to detect issues early, monitor ports and bandwidth, and troubleshoot problems quickly, helping maintain uptime and optimal network performance.
Yes. OpManager monitors the health of the entire stack as a single unit while also providing visibility into individual stack members and ring redundancy.
To prevent sudden hardware failures and thermal shutdowns, you must track a switch's environmental and internal physical sensors alongside standard performance metrics. Key metrics include device temperature, cooling fan speeds, and Power Supply Unit status. Keeping tabs on these sensors allows you to isolate degradation early and plan hardware replacements before a device fails.
You can isolate network congestion by continuously tracking interface traffic, errors, packets, and discards. Monitoring received and transmitted traffic trends allows you to expose bandwidth saturation, congestion, or chatty devices across specific interfaces. Additionally, tracking specific error types, such as Cyclic Redundancy Check errors or duplex-related symptoms, helps determine if the slowdown is caused by heavy data volume or physical infrastructure flaws. This granular data helps you balance loads across interfaces and determine if your bandwidth growth justifies capacity expansions.
Automated switch port mapping eliminates manual tracking by instantly linking every connected device to its exact physical port. It provides a real-time ledger that maps MAC addresses, IP addresses, DNS details, device vendors, and VLAN assignments. By using a visual port-panel layout, you can view your switch as it physically exists in the rack. This makes it easy to spot unused ports, identify link failures or flapping ports, and catch instances where a port is negotiating at incorrect speeds.
You can resolve unreachable endpoints and cross-segment communication issues by utilizing automated discovery to track VLANs across all ports. This visibility allows you to easily identify when a port has been mapped to the wrong virtual network or when an unused VLAN remains tied to an active port. Keeping your network segmentation clean and properly audited ensures that traffic moves seamlessly between authorized zones, preventing configuration drift and maintaining compliance without requiring you to check individual switch command lines manually.
