why do we need network management system

widely used in the information technology arena. Humans are always looking at ways to decrease effort whilst maximising output. A good example of how automation has decreased the need for human intervention is network management. Network Management Systems (NMS) aids IT departments in the complex task of keeping environments safe, secure and optimised. This article discusses how network management tools aid busy IT professionals in the daily monitoring of complex systems that span large geographical areas. Looking at Internet Service Providers (ISP) and the sheer complexity of the environments they administer, makes the case for network monitoring tools evident. With large customer volumes, both private individuals and businesses, ISPвs would find it impossible to manage their service offerings without the use of automated monitoring and alerting tools. Since monitoring these environments arenвt isolated to only keeping an eye on hardware; Service Providers need to understand consumer utilisation trends in order to provide first class services to its customers. So why is network management a top priority? Todayвs networks are much more complex than in days past. With a globalised business world, networks have become increasingly borderless and span vast geographical areas. The Internet has acted as a convergence tool where historically disparate activities are now reliant on it. We rely on the web as a work tool, a source of information, entertainment, communication and other various things. Without network management tools, ensuring peak performance and availability would be an impossible task. Hereвs just a few ways that network management and its associated tools aid in keeping networks up and issues at bay:
Around the clock monitoring: Humans would never be able to monitor each and every device on networks.

Software that is able to poll and check on the health of network hardware ensures that IT staff are in the know of potential issues on the horizon. Pre-emptive Alerting: Alerts bring to attention signs of bigger issues in your environment. Crucial to prevention is having the right information on hand to take corrective steps that ensure the stability of your network remains uncompromised. IT staff understandably cannot be everywhere at all times. Network monitoring solutions are the invisible team members who keep you in the know. Information Gathering: Large networks produce incredible amounts of information that if leveraged intelligently, puts IT departments on the front foot when it comes to network management. Network management tools gather metrics on the various devices on the network that IT can then leverage to perform analyses, draw reports and make accurate forecasts on the future requirements of their environment. Security: Security risks are an intrinsic part of the information age. Threats come in various forms that ultimately compromise the safety and privacy of company and private information. Network monitoring plays a significant role in minimising the threat posed to the security of information. The evolution of the technological landscape comes with its unique set of challenges. In a world that demands access to the web around the clock, network monitoring plays a vital role in how effectively technology professionals cater to this ever-increasing demand.

Network monitoring systems provide a first line of defense when applications go down or when performance begins to deteriorate. Network availability monitoring tools help networking teams assess the health and availability of their network devices, as well as the overall network. Network monitoring systems can track bandwidth utilization, uptime, availability and response times of networked devices, and they provide detailed reports and with troubleshooting. The market for network management systems can be confusing, however, as there's and integrated hardware appliances that offer similar functionality, but with varying degrees of integration and performance. Some network availability monitoring tools have fully integrated architectures that require only a single piece of software, whereas other tools may include several individual components, such as, a database, an analytics server or user console that must be installed and managed separately. There's a that must be addressed before selecting the network availability monitoring tool that will best meet your organization's needs. Among them, which devices do you plan to monitor? Does your organization need to monitor just one site or multiple networks across several locations? In addition to, how will this network monitoring tool integrate with your existing systems? Determining which core functions your organization requires can be a daunting task.
