Demystifying the OpenTelemetry Collector: The key fundamentals

OpenTelemetry is recognized as a key open standard for instrumentation in the software observability domain, with the OpenTelemetry Collector being a vital component for maximizing its use in cloud-native environments. The Collector is an executable that collects, processes, and exports telemetry data to various backends, offering modular and customizable data pipelines for traces, logs, and metrics. It comprises several components, such as receivers, processors, exporters, and connectors, enabling flexible data handling. The Collector can be deployed in different architectures, such as a gateway or agent, and comes in two official distributions: core and contrib. Monitoring the Collector's health and performance is essential, with key metrics including resource utilization and processing latency. Users can experiment with the Collector through New Relic's OpenTelemetry demo app and engage with the community for further learning and contribution opportunities.
