What is instrumentation?

Instrumentation is the use of measuring instruments to monitor and control a process. It is the art and science of measurement and control of process variables within a production, laboratory, or manufacturing area.

Some Monitoring Theory

• MetricA specific set of measurements using a specific type of instrumentation.

• SampleOne reading of a metric.

• FrequencyYour sampling rate – how often you sample the metric.

• Instrumentation TechniqueHow you are sampling your metric – at what point, using what method, in

what depth, with what frequency.• Instrumentation Point

What exact point in the system is being instrumented• Instrumentation Method

Exactly how the metric is being sampled

Some Monitoring Theory

Instrumentation Method Approaches

• PassiveReading metrics off a running system without generating load

(mostly)• Active

Specifically requests a metric, or provokes activity from the system to create metrics.

• Application Performance Management (APM)The monitoring and management of performance and availability

of software applications. APM strives to detect and diagnose application performance problems to maintain an expected level of service. APM is “The translation of IT metrics into business meaning ([i.e.] value)."
