ColdFusion writes its logs through Apache Log4j2 under the hood, and in 2025 the right logging strategy is to move from plain-text log lines to structured JSON logs, then ship them to a centralized platform (ELK/Elastic, Splunk, Graylog, or Grafana Loki) for search, dashboards, and alerting. In practice: keep using ColdFusion's native cflog/writeLog (optionally wrapped in a thin Logger.cfc that emits JSON with a correlation/request ID), configure JSON output, and use a log shipper (Filebeat,
