To talk about network monitoring, we first need to explain what a network is and also how it works. A few years ago, of course, it was possible to imagine a business with manual transactions and the use of technology only for some automation and machines.
Nowadays, it is impossible to talk about companies or any other type of organization without thinking about the internet.
Thus, it is through her that everything works.
What is the network?
A computer network, or data network, is a set of connected machines capable of exchanging information and resources with each other.
For example, printers, emails, internet, among others.
And these connections can be made in two ways: the wired network (wired networks) or wireless network (wireless networks).
This exchange of information must be secure in such a way as to ensure the integrity of both the company, the users, and the data to be transmitted.
For this, the network monitoring services are used. Through some specific software for this purpose, it is possible to control everything that happens.
What is network monitoring?
Managing a computer network without monitoring the network is like flying a plane without instruments.
A major challenge for network administrators and IT analysts responsible for infrastructure is to ensure that IT articles are available in such a way that the lowest possible level of disruption to these services occurs.
The vast majority of companies, whether medium or large, end up with a service contract to constantly evaluate the quality goals of these services. Know more information about the network monitoring job description and salary details.
High service availability brings reduced downtime.
Downtime is the time of a broken network, server downtime due to a service that is not working, an update that was not well implemented, among others.
As a result, it brings losses to the company.
To illustrate: Imagine a company that operates by selling online services. Then during a black Friday period, one of your servers crashes due to a problem that was not being observed.
The amount of lost sales is likely to bring huge losses that could be avoided if the network were being monitored.
For this reason, the company needs to have tools that continuously monitor the network to avoid problems and bring bad user experiences.
