requestreaches
Requestreaches is a metric used in distributed systems to quantify how far a client request propagates through a network of services. It measures the depth of processing the request experiences, defined as the maximum number of distinct processing nodes that handle the request from origin to completion, or until it is dropped or fails. Depending on implementation, it can be expressed as an integer count of hops or as a depth in a call graph.
Calculation and measurement are typically based on distributed tracing or log correlation. Tracing tools record the
Variants and interpretations exist. Inbound requestreaches refers to how far a client request travels from the
Limitations include dependence on accurate tracing data, handling of retries, caching, and fan-out patterns, which can
