Downsampling & Aggregating Metrics in Prometheus: Practical Strategies to Manage Cardinality and Query Performance
A comprehensive guide to downsampling metrics data in Prometheus with alternate robust solutions.
In telemetry jargon, a pipeline is a directed acyclic graph (DAG) of nodes that carry emitted signals from an application to a backend. In an OpenTelemetry Collector, a pipeline is a set of receivers that collect signals, runs them through processors, and then emits them through configured exporters. This blog post hopes to simplify both types of pipelines by using an OpenTelemetry extension called the Headers Setter.
