Mastering Logging in Java
summary
Comparisons show java.util.logging, Log4j, SLF4J and Logback in use, with Log4j requiring Log4j >= 2.17.2 after four 2021 CVEs; SLF4J provides an API facade, Logback implements that API. Practical recipes cover class-named loggers, lazy lambdas, async writers, rolling files (1 MB for tests, 10–50 MB or 2 GB in examples), and format/layout choices. Distributed setups use ELK (Elasticsearch, Logstash, Kibana), Splunk or Loki. Tracing uses micrometer tracing adds trace IDs (plus actuator) to correlate multi‑service logs.
