In this section, we will discuss what infrastructure means in the IT world, how we can collect data to monitor it, and why you should bother monitoring infrastructure at all.
Understanding infrastructure
In modern complex application architectures, infrastructure components can include (but is not limited to) physical servers, virtual machines, databases, containers, appliances, networks, storage...
