There are three factors to consider while deciding whether to use a single network management tool or a variety: ease of use, cost, and function. The arguments always tend to favor one tool but that does not suffice the demands of large enterprises. A thorough analysis of the above-mentioned factors is crucial to gain maximum benefits from any network management strategy.
Ease of use is an essential consideration in the current IT environment, as the team's time and attention are at higher relevance than ever before. Network administrators and engineers prefer the ability to quickly set up and modify monitoring. They also want easy access to any pertinent information and require a tool that proactively alerts them about any particular changes in the environment. If one network management tool is too difficult to operate for critical use cases, teams will choose something that better satisfies their operational needs. As technology progresses, these needs incorporate the competence to use an API to maintain the tool. As an example, teams could use an API to configure the tool to properly monitor a new virtual machine or application.
Cost is another important consideration in network management strategies, especially when debating the use of one management tool or multiple. Many deployments that use a single tool for everything are not successful because a sudden accrual of new environment entities generates tremendous licensing costs. Tools that previously were useful for monitoring physical workstations, servers and switches can at times become too expensive due to virtualization, a profusion of end-user devices or the rise of containers. Open source tools, however, are helpful against cost issues.
Functionality is also a persistent issue while working on network management tools. Major monitoring platforms tend to grow slower than monitoring needs. New commercial and open source tools come up constantly, and IT teams are quick to implement them. But even if a preferred tool evolves to meet the need in question, the target needs to keep changing and so do the corresponding issues.
