Metrics for strategic instrumentation

Instrumented systems coverage: The percentage of systems that are instrumented to collect telemetry data which provides broader visibility into the performance and health of the systems and allows teams to identify any gaps in their monitoring coverage. Calculate the number of instrumented systems, divide by the total number of systems, and multiply by 100 to obtain the percentage.

SLO adherence: The percentage of time a service meets Service Level Objectives (SLOs), indicating that the service is consistently meeting its performance and reliability targets, making for a better user experience. To measure this metric, calculate the amount of time the service meets its SLOs, divide by the total time, and multiply by 100 to obtain the percentage.
