Network Monitoring

Best Network Monitoring Tools for 2023

Network monitoring is the process of monitoring and analyzing network performance, traffic patterns, and activities. Network monitoring tools are a crucial part of any network administrator’s toolkit. They allow you to find out what’s happening on your networks and how your devices are performing. And with so many different types of monitoring tools available, it can be difficult to know where to start. This article aims at giving you some ideas about the best network monitoring tools for 2023.

Why Monitoring Tools?

Monitoring tools enable network administrators to monitor the network for problems caused by overloaded and/or crashed servers, network connections, or other devices. The best monitoring tools provide data that helps users identify potential issues before they become a problem.

Network monitoring is an important part of any business. It helps you to detect and fix problems before they become serious. This also helps you to plan for growth and reduce costs. It can even help your business save money on energy bills.

Some Main Advantages of Network Monitoring

Monitoring is important because it alerts you to potential problems and helps you fix them before they become big problems. You should monitor your network for these four things:

#1: Bandwidth Monitoring

Bandwidth monitoring is the process of measuring the amount of data that passes through a network in a given time period. It allows you to see what applications are using the most bandwidth. And where they are located on your network, so you can prioritize them for better performance when necessary.

#2: Failover Router

The failover router is a device that provides redundancy and fault tolerance. Failover routers are used to provide network traffic when a primary router fails, by taking over the role of a failed device.

The failover router has two roles:

  • Backup Router – This role allows you to configure it to take over your network after you’ve lost access to your primary router. You can also set up some parameters for how long it should wait before switching out of its backup mode into active mode again.
  • Data Collector (DCL) Server – The DCL server collects data from all connected devices within its range so that it can record information about each connection.

#3: Intrusion detection system (IDS)

An intrusion detection system (IDS) is a computer security tool that monitors network or system activities for malicious activities or policy violations. Intrusion detection systems can detect network intrusions, viruses and denial-of-service attacks. They are also used to monitor user activity within the network to ensure that it’s safe for employees to use the system.

#4: Network Time Protocol (NTP) Server

NTP is a protocol for synchronizing time over a network. It uses a client/server model, where the server is a centralized computer that adjusts the local clock of all other computers in the network.

The server has information about its own time, which it can share with clients who ask for it. Clients use this shared information to synchronize their clocks with the server’s clock, which allows them to perceive accurate time even if they aren’t connected directly to each other or any other sources of accurate timekeeping data like atomic clocks or GPS devices.

Types of Network Monitoring Tools

Network monitoring tools can be used to identify potential problems in a network by providing real-time information on devices that are connected to it. Below are various types of network activity monitoring tools available in today’s market.
