Network Monitoring
Identifying performance issues within the network is only one of the reasons to perform structured monitoring. Security issues also require constant monitoring. In the following sections, we’ll look into both types of monitoring and cover some of the best practices and guidelines for success.
Baselines
In networking, baseline often refers to the standard level of performance of a certain device, or to the normal operating capacity for your whole network. For instance, a specific server’s baseline describes norms for factors like how busy its processors are, how much memory it uses, and how much data usually goes through the NIC at a given time.
A network baseline delimits the amount of bandwidth available and when. For networks and networked devices, baselines include information about four key components:
- Processor
- Memory
- Hard-disk (or other storage) subsystem
- Network adapter or subsystem
After everything is up and running, it’s a good idea...
