OpenTelemetry Spring Boot 启动器提供了开箱即用的插桩，你可以使用额外的插桩来增强它。
Log4j2 插桩
你必须将 OpenTelemetry appender 添加到你的 log4j2.xml 文件中：
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN" packages="io.opentelemetry.instrumentation.log4j.appender.v2_17">
<Appenders>
<OpenTelemetry name="OpenTelemetryAppender"/>
</Appenders>
<Loggers>
<Root>
<AppenderRef ref="OpenTelemetryAppender" level="All"/>
</Root>
</Loggers>
</Configuration>
你可以在 Log4j 插桩库中找到 OpenTelemetry appender的更多配置选项。
| 系统属性 | 类型 | 默认值 | 描述 |
|---|---|---|---|
otel.instrumentation.log4j-appender.enabled | Boolean | true | 启用使用 OpenTelemetry 实例配置 Log4j OpenTelemetry 附加器。 |
插桩库
你可以使用 OpenTelemetry 插桩库 配置其他插桩。
