The values extracted from the CLI can be easily extended into a scripting system, which includes some more advanced functionalities such as alerts or triggers. In an Enterprise context, however, it is often required to gather information that is not directly exposed by the CLI or to create graphical views or even business intelligence from this data. We will show which tools are commonly used for this purpose.
