In information technology and telecommunications, Local Area Network (LAN) is a term describing a computer network connecting multiple computers, including peripheral devices.

There are numerous LAN monitoring software you can use to secure your local network as well as extended networks. Many of them are available for free. Let’s find out which is best for you!

How can I monitor LAN networks?

There are many systems for monitoring your LAN network. If you’re asking yourself what you check in LAN software, rest assured that we can help you with that.

The vital parameters are, for example, the disk space, the percentage of processor usage, memory, and disk usage, network connectivity, etc.

It’s easy to set alerts for all these settings in advance. In this manner, you’ll avoid space saturation and server blockages.

What to check when buying a LAN monitoring tool?

We will highlight the main features that you need to look for when getting a LAN monitoring tool:

  • Alerts – you should receive information about failures and stress from the monitor.
  • Analysis tools – to explore the network.
  • Customizations – in case you want to write your own scripts to automate reporting, the system should allow you to do that.
  • Visualization – you need to be able to see the status of the overall network.
  • Multi-vendor compatibility – the monitoring system and all your existing equipment should communicate.

In this post, we’ll list the most useful LAN monitoring software that you can use for your Windows computer network.

Nagios LAN software

Nagios is a monitoring system that allows you to identify and resolve any IT infrastructure issues before they have any negative consequences.

Expert tip:

Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.
We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

It is considered the de facto standard in network monitoring. And it’s true because it’s one of the first tools that did it right. Before Nagios there were others, but they were good only for specific tasks.

The first version of Nagios is from the last century: 1999. Since the official launch, the technology has evolved: Nagios has done it through an ecosystem of add-ons or third-party add-ons that try to complement the features that are missing.

Nagios is able to monitor network devices, systems, and services. Furthermore, the plugin system makes it versatile and adaptable to any monitoring requirement. It is also possible to write custom plugins.

Let’s see some of its most important features:

  • Supports hundreds of third-party addons
  • Set up alerts to notify you when potential threats arise
  • Get all of your log data in one location
  • Monitors routers, switches and more
  • Effective application monitoring

Zabbix – Good performance monitoring

Zabbix landed on the market in 2001. It is a fully developed tool, not a fork of Nagios. Its main characteristic is that it has a more holistic vision of monitoring, covering performance, not only states.

In addition, it has a WEB management system that allows control in a centralized way, without cumbersome configuration files, as happened to Nagios.

You will benefit from these core features:

  • Run the app locally or in the cloud
  • Scalable to any infrastructure
  • Native encryption support between all of the components
  • Backed by 250+ global partners

Pandora FMS – Great for IoT monitoring

Pandora FMS was released in 2004. This is a monitoring framework that supports infrastructure monitoring (networks and servers), performance monitoring, and applications (APM) to transactional business monitoring (BAM).

It has a centralized management system and is based on a SQL relational database.

Like Nagios, it has an Enterprise version, but its OpenSource version is more than enough to implement any monitoring need.

Neither Nagios nor Pandora FMS is limited versions like those of other manufacturers, but they lack some features oriented to large environments.

Consider the best features of this tool:

  • Support for over 500 plugins
  • Excellent for students and developers
  • IoT monitoring
  • A single platform to collect and display information

Comparing Zabbix, Nagios and Pandora FMS

  • User Configuration and Management

Zabbix has a web management interface that is centralized through the database, just like Pandora FMS does.

Nagios, however, is still managed in thousands of sites through complex text files, scripts, and manual processes, which also make it necessary to use third-party tools for deployment.

This has the advantage that Nagios needs fewer resources by not using a database to store information. The difficulty in management means that you have a team of people who manage Nagios.

  • Plugins and monitoring out of the box

Both Zabbix and Nagios need plugins in order to offer a set of complete functionalities.

Zabbix lacks an official plugin library for the community, but it does have a list of OIDs for SNMP queries.

Nagios has a huge library, but it’s not that well maintained.

Pandora FMS has a smaller library than Nagios (it does not reach 500 plugins), but it is better maintained. The tool comes with a collection of plugins and modules ready to use.

Zabbix has a powerful system for defining templates and triggers based on regular expressions.
