In reality, in any non-trivial installation, there are multiple tools collecting, storing and displaying overlapping sets of metrics from many types of systems and different levels of abstraction. For each resource there’s usually an underlying or bare metal version, a virtualized resource and sometimes also a containerized resource.

In a nutshell, a data pipeline is a distributed system. Processing latency is minimum If only you can infinitely scale your data pipeline, processing latency can be guaranteed to be minimum, but we know for sure that is not true. This can be efficient at the beginning but counter-productive in a long run.
