Best LAN Monitoring Monitoring Tools and Software

by Brenna Miles - Last Updated: April 22, 2024

Here’s the thing about small businesses: no one has one job to focus on. As a small business owner, you may find yourself as the CEO, CIO, CMO, CFO, and the network administrator, all rolled into one.

You may not have the staff to back you up or the talent for reinforcements. Plus, you may find yourself sticking to a tight budget as you focus on ramping up your business. Your network is important, no matter the size. You must have visibility into your network to avoid disaster – even if you’re working with a small group.

Let’s dive in and discuss ten, must-have tools for small business networks.

The best LAN Monitoring Tools for SMB

Our methodology for selecting LAN monitoring tools and software

We reviewed various LAN monitoring tools and analyzed the options based on the following criteria:

  • Alerting and reporting capabilities
  • Ease of use and deployment
  • A facility to analyze LAN performance over time
  • Graphical interpretation of data, such as charts and graphs
  • A free trial period, a demo, or a money-back guarantee for no-risk assessment
  • A good price that reflects value for money when compared to the functions offered

1. SolarWinds NetFlow Traffic Analyzer – FREE TRIAL

SolarWinds NetFlow Traffic Analyzer

The SolarWinds NetFlow Traffic Analyzer tool focuses on traffic patterns around a network. This monitoring system offers a little too much functionality for very small businesses, but as your enterprise grows, you will find that your network becomes very complicated very quickly. This tool prevents bottlenecks from occurring due to overloaded switches.

Why do we recommend it?

SolarWinds NetFlow Traffic Analyzer is a traffic monitor that extracts flow data from switches and routers using the NetFlow, sFlow, J-Flow, and IPFIX protocols. Not all device manufacturers load the same packet sampling protocol on their devices, so this range of capabilities means that the NetFlow Traffic Analyser can operate in multi-vendor environments.

The NetFlow Traffic Analyzer will communicate with network devices using special traffic management protocols called NetFlow, IPFIX, sFlow, J-Flow, and NetStream. The tool can categorize traffic by application, using a system called NBAR2. This lets you see which types of applications are creating the largest amount of network traffic and you can also segment traffic data per endpoint.

Features in this package also let you implement traffic shaping to get the best value out of your network devices. Alerts in the monitor draw you back to the dashboard if problems start to build. You can get these alerts sent to you by email or SMS.

Who is it recommended for?

This is a large package that ordinarily would be the choice of big companies. However, there is nothing to stop small businesses from buying it. The software runs on Windows Server and you also need to have the Network Performance Monitor, which discovers and maps networks and monitors network device statuses.

Pros:

  • Supports multiple protocols like NetFlow, great for monitoring Cisco equipment
  • Both tools work well alongside each other to help view traffic patterns and bandwidth usage
  • Easy to use interface automatically highlights bandwidth hogs and other network traffic outliers
  • Scales well, designed for large enterprise networks
  • Can view traffic on a per-hop basis, allowing for granular traffic analysis

Cons:

  • Built for enterprise use, not designed for small home networks

This system installs on Windows Server. SolarWinds offers the NetFlow Traffic Analyzer on a 30-day free trial.

EDITOR'S CHOICE

SolarWinds Network Traffic Analyzer is our top pick for a LAN monitoring tool that is suitable for small businesses because it works together with the SolarWinds Network Performance Monitor to discover, document, map networks, and then track traffic patterns. This system is able to identify VLANs and track the traffic passing over them, looking for irregularities that can disrupt VoIP calls and video conferencing. The system also stores metrics to be recalled for analysis. This gives you the guidance to decide how much capacity your network really needs. This could result in a reduction of overprovisioned hardware or strategies to expand capacity – either through traffic shaping or hardware expansion.

OS: Windows Server

2. ManageEngine OpManager – FREE TRIAL

ManageEngine OpManager Traffic Report

The benefit of ManageEngine OpManager is that it monitors servers and virtualizations as well as networks.  As your business grows, you will periodically have to invest in large servers but will start off with a lot of wasted processing power. You can distribute this to dedicated appliances for applications and dumb terminals for users through virtualization.

Why do we recommend it?

ManageEngine OpManager monitors networks and endpoints. The package uses the Simple Network Management Protocol to poll devices for status reports. The responses enable the package to create a network inventory and network topology map as well as produce live status reports. This is a software package for Windows Server and Linux. It is also available as a service on AWS and Azure.

Tracking virtualizations is complicated so an automated tool is necessary. The concept requires insight into the performance of both networks and servers, so the monitoring combination of OpManager is ideal for the task.

The ManageEngine system discovers all of your network and writes up a network inventory. The system rechecks every few minutes, so that list of devices is constantly updated.

The package includes a network topology mapper. These maps are based on the network inventory, so the maps are always up to date. OpManager tracks the performance on wireless networks, cloud servers, and internet connections, as well as traditional wired on-premises systems.

Who is it recommended for?

ManageEngine offers a Free edition of OpManager, which is limited to monitoring three devices. That is suitable for very small businesses but any company with more devices will need to look at the paid editions that have prices starting with a package to monitor 25 devices.

Pros:

  • Can monitor bandwidth consumption as well as alert to configuration changes that could impact network performance
  • Can monitor bandwidth and resource consumption on the application level, and even drill down to identify specific users consuming the most resources
  • Supports email, SMS, and webhook for numerous alerting channels
  • Integrates well in the ManageEngine ecosystem with their other products

Cons:

  • Takes time to full explore the all the options available in the ManageEngine software suite

ManageEngine OpManager installs on Windows Server and Linux. If you have an account on AWS you can look in the AWS Marketplace and buy OpManager there. The software will then run on your AWS account instead of on a server on your site. The same is true for Azure accounts.

ManageEngine offers OpManager on a 30-day free trial.

3. Atera – FREE TRIAL

Atera Dashboard

Atera is a SaaS platform that is designed to support managed service providers (MSPs). The package includes a network monitoring system as well as administration tools for servers and software.

Why do we recommend it?

Atera is a system administration package that is hosted in the cloud. The system includes automated network monitoring services that can access remote networks across the internet. The package also monitors endpoints and has endpoint management utilities, such as a patch manager. The network monitor will raise an alert if it discovers a problem with a network device.

The key element of Atera that makes it very suitable for small businesses is its pricing structure. The service is charged for by subscription with no setup fees or lock-in period. The rate is set per technician, so independent technicians get all the same utilities that large corporations get.
