Many network managers believe that it is often more challenging to monitor and manage a Local Area Network (LAN) than a Wide Area Network (WAN).
A typical office LAN can be comprised of hundreds of different types of devices, working on different segments of the network.
It is still more challenging when different vendors manufacture all these devices.
LAN equipment such as routers, switches, servers, wireless APs, workstations, and printers are critical for an office.
These devices need constant monitoring through different methods, intervals, and performance metrics.
A LAN monitoring software or tool should be capable of keeping an eye on all these devices using different techniques and showing all the collected information under a centralized management console.
It is challenging to attempt to classify the different types of LAN monitoring software out there.
LAN monitoring can be considered from a simple ping sweep application, a packet sniffer, to a predictive network outage system.
But network admins prefer the all-in-one package, the full monitoring platform that can auto-discover devices, collect information, arrange it in graphs or charts, and triggers alarms.
What is the Most Crucial task when Monitoring your LAN?
LAN should at all costs be operational, available, and secure. At a basic level, the LAN monitoring software should keep you informed in case of a drop in performance or an outage.
Receiving an alert or notification can help you act quickly and fix the network, before it affects the end-users.
Since probably most of your LAN consists of a wide range of manufacturers, it is a good idea to use a software that can monitor different vendors at the same time.
Most of the software shown below are compatible with lots of different popular vendors.
These tools are optimized with pre-configured or out-of-the-box templates and plugins that can extend LAN monitoring to hundreds of different vendors.
But as a general rule, it is always a wise idea to check if your LAN equipment is supported.
