Dynatrace's blog series delves into their advanced observability features, highlighting how their platform scales and automates AI-driven alerting and root cause analysis for custom metrics, including those from open-source observability frameworks like StatsD, Telegraf, and Prometheus. In Part 2, the focus is on using the OneAgent metric API to conduct multidimensional analysis on external metrics. This API allows seamless ingestion of performance and business metrics into Dynatrace, leveraging Davis AI for anomaly detection and alerting. The OneAgent metric API simplifies configurations in large environments by enabling secure, local HTTPS-based metric ingestion, automatically adding host information as a dimension. This feature is particularly beneficial for integrating with metric frameworks such as Spring Micrometer and Dropwizard, and the API ensures security by accepting only local requests. The blog encourages users to explore these capabilities through a free trial and previews future content on simplifying metric sending from scripts and other tools.
