The OpenTelemetry Collector: Receivers, Processors, Exporters, Tail Sampling and PII Filtering
The OpenTelemetry Collector is a separate process that decouples the application from backends and receives and processes telemetry in pipelines of receivers, processors and exporters. We set it up for Bookstore in a one-container LGTM stack, filter unneeded logs, hash the e-mail address, keep failed and slow traces with tail sampling and measure how head sampling throws away 90 percent of the orders people complain about.
