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 it 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 with the help of reliable, real-time network monitoring tools.

Requirements of a network monitoring tool

While selecting a network monitor tool for your IT environment, it is important to weigh in your current requirements and also your future needs because choosing the right one among various tools for network monitoring is crucial. 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 application and its reporting tools must provide performance insights into your network in real time. In this way, the network monitor helps you identify performance hiccups early and avoid potential outages.

Comprehensive monitoring capabilities

Employing individual network monitoring tools for monitoring various network components such as switches/routers, servers, virtual environment, HCI, applications, storage devices, etc., and also employing network monitoring tools for Windows and Linux environments separately 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 management system or network monitoring software 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. Businesses also need remote network monitoring tools for managing multiple geographical locations from one console.


In network monitoring, automation helps network monitoring solutions or network management tools to react based on threshold values or a set of framed rules/ criteria being met. With automation, the network monitoring service 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, making it an important usability aspect of your network monitoring solutions.

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. Network monitoring tools with the above features are exceptionally benefiting to your business.

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.
