Log router

As explained in Secure APIs

A log router is a component that collects, filters, transforms, and forwards log records to downstream storage or analysis systems.

A log router collects application logs as streams, then forwards them to a log aggregator for storage and analysis. It separates log delivery from the API’s main request path. section 11.5

This pattern supports security monitoring without relying on file logging, which can add performance pressure. A WAF can annotate malicious injection signals before the logs reach downstream analysis. section 11.5

A practical deployment pattern is:

  • Write application logs to standard output. section 11.5
  • Run a collector such as Logplex or Fluentd to gather and route the streams. section 11.5
  • Place the collector beside the application as a sidecar container in container-based deployments. section 11.5

How Secure APIs covers it

How deep it goes
Explains the streaming architecture, deployment pattern, and performance rationale, but stops short of router configuration.
Examples
Uses Logplex, Fluentd, a sidecar collector, and request-tracing records that exclude credit-card data.
What it assumes
Assumes basic API logging knowledge while defining sidecar containers and contrasting streamed logs with file logging.
What you can do after
Operate/configure a streamed logging pipeline and place its collector beside an application for centralized analysis.
How it connects
Connects standard output, log aggregators, WAFs, sidecar containers, container deployments, and malicious injection detection.
