Observability

Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs.

for an organization's infrastructure, this means instrumenting all compute
resources, apps, and services with
"sensors" that faithfully report metrics from
those components. It also means making those metrics available on a central,
easily accessible platform, where observers can bring them together to reconstruct
a full picture of the system's status and operation.
Observability dovetails with the devops movement, as it represents a cultural
shift away from siloed, piecemeal views into critical systems toward a detailed,
comprehensive view of the infrastructure that is shared across the organization.
