Network Monitoring Tools

Networks are the fundamentals behind businesses worldwide. It plays a pivotal role in serving your employees for administrative purposes and your clients across the continents. The networks help you keep information in a centralized location - accessible to those who need and restrict every other inbound request. So how do you provide continuous top-notch end user experience and maintain your rapidly evolving network? Only by monitoring the availability, health, and performance of your networks over time.

The need for network monitoring tools

As the importance of networks in a business environment is immense, employing sophisticated, network performance monitoring tools is vital. With a network monitoring solution, you can avoid potential network pitfalls. Network monitoring solutions aid IT admins by:

  • Providing complete visibility into the IT infrastructure 24*7 
  • Keeping them updated of the network's state in real time 
  • Identifying issues before the end users are affected 
  • Tracking and troubleshooting performance issues early 

Apart from the above, with the help of network monitoring systems, admins can now make more informed IT decisions which help in improving business continuity.

Requirements of a network monitoring tool:

While selecting a network monitoring tool for your IT environment, it is important to weigh in your current requirements and also your future needs. Some of the essential elements that a network monitoring tool requires are:

Real time monitoring

Learning that your network is down from your end users is the nightmare that every IT admin tries to avoid. The network monitoring tools must provide performance insights into your network in real time. This helps you identify performance hiccups early and avoid potential outages.

Comprehensive monitoring capabilities

Employing individual network monitor tools for monitoring various network components such as switches/routers, servers, virtual environment, HCI, applications, storage devices, etc., is more trouble than help as the tools themselves require constant management, additional resources, and there is also a certain learning curve associated with each network monitoring tool. Therefore, the network performance monitoring tools should support extensive monitoring in a single console.


Network scalability is an important aspect to be considered when selecting enterprise network monitoring tools. A network monitoring tool can be called as scalable when it is more adaptable to the changing needs or demands of the business or users. Scalability helps a network to stay in par with increased productivity, trends, changing needs and new adaptations. Scalabiity ensures that the overall network performance does not significantly degrade, even if the size of the network is increasing.


In network monitoring, automation helps network monitor tools to react based on threshold values or a set of framed rules/ criteria being met. With automation, the monitoring tool can automatically detect and troubleshoot problems (proactive monitoring), send alert notifications, forecast storage growth, and much more. When you are monitoring and managing multiple devices in your environment, automation comes in super handy and saves you ample time and resources.

User Management

User Management helps organizations ensure network security by providing access to the designated users only. Apart from providing access to users with roles, the network monitoring tool should also define the scope for users. This helps IT teams with multiple staffs as it clearly defines their operational boundaries.

All the above mentioned functionalities make a good network monitoring tool into a great one. Now, let us discuss the network monitoring system that checks all the boxes above - OpManager.

OpManager - powerful network performance monitoring tool

ManageEngine OpManager is an all-inclusive, easy to use network monitoring system. It monitors switches, routers, physical and virtual servers, storage devices, printers, network interfaces, and any networking devices in your IT environment - all in a unified console.

Switch/Router monitoring

Network switches and routers form the backbone of any IT infrastructure. Any issue with switch breaks the end user connectivity with the network. Using OpManager, you can monitor switches, and routers from the likes of Cisco, Juniper, Aruba, ZTE, and many other vendors for availability, health, and performance in real-time for 2,000+ parameters and avoid possible network pitfalls. Apart from monitoring switches, OpManager maps switch ports to devices and monitors the availability of the switch ports.

Network interface monitoring

Network interfaces are one of key performance indicators (KPI) as they help identify network performance degradation at the earliest. OpManager monitors interfaces using SNMP and provides a single customizable dashboard to view and analyze bandwidth performance and network traffic for your IT network. You can monitor interfaces by checking the availability status of interfaces and monitor traffic speed on the interface, errors, discards, etc. using OpManager.

WLC monitoring

OpManager's multi-vendor WLC monitoring module allows you to keep your network intact by providing in-depth visibility of your wireless LAN controller (WLC), its associated service set identifiers (SSIDs) and access points (APs). Cisco's WLC monitoring tool in OpManager allows direct discovery of Cisco WLC and their associated SSIDs, APs and helps you monitor the overall performance of your wireless network with the help of Cisco WLC monitor. The WLC snapshot page provides inventory information, the device availability status, and other similar information. In addition, knowing the top five access points based on usage tells you who the top talkers are in your WLC environment, and custom dials display information on various parameters, including CPU and memory usage.

WLC monitoring 

VPN monitoring

Organizations allow connections into their networks through VPNs for their remote workforce. These connections can sometimes be compromised, resulting in data theft or network attacks. With OpManager, you can monitor your VPN by tracking the number of active VPN sessions, VPN tunnel status, and VPN tunnels count in real time, and also receive instant alerts on VPN connection regularities making your network secure and keeping your remote productivity issues at bay.

Hybrid environment monitoring

Every organization's network has unique needs, so top-of-the-line networking technologies are employed to address them. This helps networks deliver business services but also poses a challenge with monitoring and managing the network. Using multiple tools for monitoring is not efficient and cost effective. With OpManager, apart from monitoring switches, servers, etc., you can monitor VMware, Hyper-V, XenServers, Cisco UCS, Nutanix infrastructures, and more, all within a unified console. Additionally, you can monitor your WAN with Cisco IP SLA using OpManager.
