Thus, LAN monitoring tools are essential. Due to their automation and simplification, these tools help increase network administrators’ efficiency and reduce their waste of time.

LAN monitoring tools keep the network well-maintained and provide additional visibility in the complex LAN environment.

Thus, even though the top LAN monitoring tools are not free, they are an excellent investment for network administrators and businesses.

How to Choose a LAN Network Monitor?

There are a large number of LAN monitoring tools in the market with multiple features. However, all the best LAN monitoring tools use Simple Network Management Protocol (SNMP) to check the network devices’ functioning.

Some of the LAN tools offer shiny features which aren’t as crucial as the intuitiveness, compatibility with a broad range of network devices, and reliability of the best LAN monitoring tools.

Depending on the budget and a company’s requirement, the best LAN network monitor tool might differ. It is time that you do not choose a clunky monitor software for your network administrators who already use a lot of them.

Here is a list of general attributes that you should consider when you choose a LAN monitoring tool:

  • Compatibility: The LAN you choose must communicate with other network devices efficiently and not be made for a single vendor. If you choose the one with support for a single vendor, you will become dependent on that vendor even if its solution isn’t the best.
  • Reports: Most LAN monitoring tools come with the ability to generate comprehensive reports containing all network devices, making it easier to explain the functionality to non-IT managers by the network administrators. Thus, the functionality to create comprehensive reports is a must for your LAN monitoring tool.
  • Customization: The LAN network monitor tool you select should be customizable to meet various LAN deployment environments’ needs.
  • Features: Many network monitoring tools offer shiny features, but not all of those are of use to you. Choose wisely about what features you need and never for extra features because vendors of the network monitoring tools are constantly in competition to develop new features to stay in business.
  • Alerts: You need to ensure that the one you choose is a proactive LAN monitoring tool that incorporates a feedback system. This system can alert the network administrators about the network problems beforehand so that their solution can be cost-effective and straightforward.

How Does a LAN Monitor Tool Work?

Most LAN monitor tools use Simple Network Management Protocol (SNMP) to fetch operational data such as a processor or memory utilization from the monitored devices.

These tools check network devices such as network-attached devices, servers, and workstations to identify any device that isn’t working according to required metrics. They notify the network administrators if any device stops responding.

The tools ensure that network administrators know about all the devices’ general health in a network and the network.

General Features of A LAN Monitor

The LAN monitoring tool that you choose must provide graphical insights about the tool’s environment.

The features generally present in a LAN monitor tool are:

  • Detection of suspicious activities
  • Checking file activities on critical servers
  • CPU utilization of Workstations, Servers, and Network appliances
  • Automated warning & alerts
  • Keeping an eye on user activity

Benefits of LAN Monitoring Software Tool

When shouldn’t you use Network Monitoring Software?

Network monitoring software performs complicated tasks in the background to provide you with a comprehensive overview of the network.

Thus, this tool requires a lot of time to analyze IT infrastructure’s performance and generate a comprehensive report.

You must make sure that you do not use this network monitoring software to diagnose simple and small networks.

What To Look for in a LAN Monitor?

From small packet sniffing tools to comprehensive network administration systems, LAN monitoring differs hugely.

To ensure that you are monitoring a network effectively, the tools should track hardware capacity and utilization levels, operational or offline status of devices in real-time, and provide alerts proactively before the network’s overall performance gets affected.

Numerous tools in the market offer unique features and approaches, and some come with a free trial. Having these many options makes it challenging to choose the best LAN monitoring service.

However, every organization has varying needs. While choosing the best network monitoring tool for you, you must look for the one that offers features best suited for your business and activities and your pocket.

The LAN monitor you choose must be flexible devices that support maximum devices from multiple vendors to ensure compatibility.

If the tools aren’t flexible, you will be forced to replace the LAN monitor with more suitable alternatives or overlook specific equipment, which will be costly.

Usually, when we talk about LAN, we leave out the wireless networks; however, while choosing the LAN monitor tool, you can consider a LAN monitor with wireless router monitoring included. This will provide an all-in-one solution without any need for additional network monitoring tools.

Here are a few key features that are a must-have in LAN monitoring tool:

  • Network switch monitoring
  • Monitoring of storage space on all devices
  • CPU utilization monitoring in network appliances, workstations, workstations, etc.
  • Visibility of user activity
  • Monitoring suspicious network activity such as flood attacks, unauthorized access, etc.
  • Router performance monitoring
  • Monitoring hard disk space on all devices
  • Critical server file activity checks

What can affect network performance?

Network issues can severely affect a business due to downtime and slow-moving traffic. These can cause dropped or missing packets and communication loss between devices.

The network’s problem is mainly due to three causes: addressing errors, excessive traffic, and damaged equipment.

Keeping a smooth traffic flow is essential. Smooth traffic can be achieved by making sure that the network devices don’t reach their capacity.

If the device exceeds the capacity, then the request packets will start getting queued. These packets will be dropped if the queue gets full. This will also affect TCP communication because the acknowledgment packets might get dropped and will need to be sent again.

Thus, as the number of traffic increases on the network, the receiving application will slow down and cause the software and related services to freeze.

Loose hardware connections can also cause network traffic problems as they will function some of the time and not function the other time, which makes it harder to detect the faulty hardware.
