The network is and has been one of the critical components of business success, irrespective of the size of the organization. When a network faces downtime, customers and employees cannot access critical information and in turn, they cannot communicate leading to loss of productivity and loss of revenue. A network monitor software allows businesses to operate more fluently, prevent revenue loss, and also cut costs. Here are a few aspects you need to know about network monitor.

The elusive search for a good network monitor tool

A network monitor application helps to keep your enterprise network operating at its maximum capacity. Enterprise networks are becoming increasingly complex every day to meet the rising need and demand for digital business solutions. A business needs to ensure that its network is performing at the speed and efficiency required of it. An essential tool for enterprises to measure their network performance is to utilize a system that constantly monitors a network for slow or failing components. In more practical terms, a network monitor is a software that continuously observes your network and the data that flows through it. Network monitoring tools notify the network administrator in case of outages or issues.

Why are network monitoring tools important?

Network monitoring tools play a vital role in the following aspects:

  • Optimize network performance: The network monitor application captures data directly from the network, interprets this data, and displays it via a dashboard, which allows you to get a glimpse of your network, even on the go.
  • Gain in-depth visibility: .A network monitoring tool offers in-depth visibility into network architecture to help you visualize performance and locate devices easily in the event of downtime.
  • Manage faults better: If the network monitor finds any issues with the network or signs that might indicate a potential possibility of failure, it will alert your IT team to the problem so they can get straight to work on fixing it.
  • Automate troubleshooting:   To help network admins save time on redundant manual tasks, network monitoring tool helps you automate certain repetitive tasks leveraging AI and ML-based algorithms.

How does a network monitor work?

Network monitoring applications are typically equipped to track network performance through multiple different methods and techniques. However, network monitoring works by performing these three steps:

Establish connectivity: Connects to network devices

One standard way a network monitor uses to connect to the network devices is through the SNMP protocol. SNMP monitoring uses management information base (MIB) to collect data from any device connected to the IP networks such as modems, routers, servers, printers, and switches. Network monitor also uses ICMP ping function to keep devices' availability in check. WMI, CLI and Telnet are also other options.

Monitor essential metrics: Keeps the network performance in check

Once connected, network monitor tool scrutinizes network performance metrics with dedicated monitors. Network monitors perform threshold based monitoring so as to instantly alert you on network issues or violated thresholds. For example, if you are curious about your company's bandwidth usage or latency/packet loss, you can set up a network monitor to observe just that and see how the latency is or how many packets are dropped in your network at any given time. If the network monitor notices that any metric is reaching critical levels, it will inform your enterprise on which devices need to be checked on.

Resolve faults: Analyzes the root-cause of network issues

When a network fault is detected, network monitor zero in to the root cause of an issue, informing you whether the fault is due to hardware or software issues, bandwidth issues, and configuration issues. Apart from alerting, network monitor also performs troubleshooting with pre-loaded scripts or commands and even automate certain actions like restarting a service, shutting down a device and more.

Why should enterprises adopt a network monitor solution?

To manage network on an enterprise level, you need a comprehensive, future-ready network monitor tool to protect network from any potential hazards and maintain network uptime. Enterprises require network monitor solution for the following reasons:

Advanced alerting:

In enterprises where there are numerous network devices, there are high chances for proxy alerts to be triggered. An efficient enterprise network management software will go beyond basic threshold-based alerting and manage flood of unnecessary network alerts due to dependencies and the like. You should also be able to send alerts via different channels such as SMS, email, web alarms and more.

Learning network issues before end users:

Network monitor solutions observe the network in real-time to alert you on performance issues even before the network team would ever discover it. This reduces the time between when a problem happens and when your enterprise learns of this. You will also know about every performance hiccup on your network especially those that are otherwise undetectable to network teams. Even if the issue is only marginally affecting performance it could be skated to something much bigger so you will want to be aware of them

Distributed monitoring:

As enterprises grow and scale across different geographic regions, you need a robust network monitor solution that provides centralized control over different branch offices, and remote sites. Also, any updates or changes done in the central site will reflect across all the networks.

Resource management:

Resources accessibility is inevitable for optimal performance of both hybrid and virtual networks. Network monitoring tool is crucial to manage resources and keep their availability in check. Network monitor tool records all the information related to data utilization, and growth in the form of reports. You can analyze the growth trends, predict storage needs and take judicious storage decisions. This will help eliminate indiscriminate storage purchases and save on the IT budget.

Multi-vendor support

When it comes to enterprise, multiple vendors will be in the picture already. Network monitor solution with support for multi vendors and device types eliminates the need to toggle multiple vendor specific tools. For example, OpManager extend its support to over 500 vendors such as Dell, HP, Juniper, Cisco, IBM and more. You can also create custom device templates to add devices from any vendor and perform monitoring.

Network monitor application requirements:


Data is valuable and can be interpreted accurately only when it is presented meaningfully to the right audience. An actionable intelligent network monitor dashboard with customizations can help achieve this. This is a basic requirement of any network monitor tool.


When a business or organization grows, network monitor solutions must be viable to change and expansion, without compromising on the reliability. Network visibility across multiple locations with real-time data sync is a game-changer for networking tools.

Support integrations

Readily available integrations to extend the functionality of the network monitor tool and offer flexibility to manage the other aspects of the network help administrators manage the entire network from the single console.

Quick technical support

Round the clock premium support with onboarding assistance, upgrade assistance and periodic health check-ups is the highlight of a top-notch network monitor system.


Everyone wants more bang for the buck. Network monitor tools must be able to monitor all the network resources and must have high scalability to support the growth of the business/organization.

Easy to install and use

The real-time network monitor has to be intuitive enough to get you started without the hassle of going through pages and pages of documentation.

Low cost

The network monitor tool has to be affordable and light on the pocket to maintain.
