Metrics

Overview

SIP3 uses vendor-neutral application metric facade called Micrometer. It allows SIP3 to send multi-dimensional QoS metrics to the most popular monitoring systems such as CloudWatch, Datadog, Elastic, InfluxDB, New Relic, Prometheus, etc.

Please read Micrometer Documentation to get more information about basic concepts, metric types, dimensional data models and specific implementation details.
