红帽全球峰会16.3.3. 配置 JSON 或普通控制台日志记录
默认情况下，控制台日志处理程序会将普通非结构化数据记录到控制台。要使用结构化 JSON 日志输出，请输入以下命令：
bin/kc.[sh|bat] start --log-console-output=json日志消息示例
{"timestamp":"2025-02-03T14:52:20.290353085+01:00","sequence":9605,"loggerClassName":"org.jboss.logging.Logger","loggerName":"io.quarkus","level":"INFO","message":"Keycloak 999.0.0-SNAPSHOT on JVM (powered by Quarkus 3.17.8) started in 4.440s. Listening on: http://0.0.0.0:8080","threadName":"main","threadId":1,"mdc":{},"ndc":"","hostName":"host-name","processName":"/usr/lib/jvm/jdk-21.0.3+9/bin/java","processId":76944}
使用 JSON 输出时，颜色被禁用，不应用由 --log-console-format 设置设置。
要使用非结构的日志，请输入以下命令：
bin/kc.[sh|bat] start --log-console-output=default日志消息示例
