In the realm of software, observability is crucial for understanding system behavior through telemetry, which encompasses metrics, logs, and distributed traces. Dynatrace leverages these 'three pillars of observability' to enhance automatic problem detection and root-cause analysis without requiring code changes. By installing a single agent, Dynatrace's OneAgent can discover and instrument processes automatically, collecting thousands of metrics and enabling distributed tracing across complex microservices environments. This approach integrates observability data to avoid siloed information, using real-time topology mapping and AI to identify dependencies and pinpoint root causes efficiently. Dynatrace collaborates with the OpenTelemetry initiative to further standardize data collection for cloud-native software, promising to enhance insights and problem-solving capabilities in large-scale environments.
