Technical requirements
In this chapter, we'll be discussing several facets of network management. While you can certainly recreate the example builds in this chapter, just be aware that your data will be different. So, while the methodology of using the various data types for monitoring or troubleshooting will remain the same, to use your data (and any issues you find that need resolution) in your environment, you will need different search terms.
That being said, your existing Linux Host or VM can be used to build any or all of the example systems described in this chapter. However, in production, you would separate these functions across one, two, or even more dedicated servers. If you are using a VM for your lab, my best suggestion would be to start from a new, clean image and build forward from there – that way, if you find any of the various Network Management Systems (NMSes) we work with useful, you can move forward with them directly into production.
The NMS...
