skywalking集成nacos动态配置

修改config/application.yml

configuration:
  selector: ${
          
   SW_CONFIGURATION:nacos}
  nacos:
    # Nacos Server Host
    serverAddr: ${
          
   SW_CONFIG_NACOS_SERVER_ADDR:192.168.229.130}
    # Nacos Server Port
    port: ${
          
   SW_CONFIG_NACOS_SERVER_PORT:8848}
    # Nacos Configuration Group
    group: ${
          
   SW_CONFIG_NACOS_SERVER_GROUP:skywalking}
    # Nacos Configuration namespace
    namespace: ${
          
   SW_CONFIG_NACOS_SERVER_NAMESPACE:db20ccfd-db01-47bd-a4d3-393b4e7df260}
    # Unit seconds, sync period. Default fetch every 60 seconds.
    period: ${
          
   SW_CONFIG_NACOS_PERIOD:10}
    # Nacos auth username
    username: ${
          
   SW_CONFIG_NACOS_USERNAME:"nacos"}
    password: ${
          
   SW_CONFIG_NACOS_PASSWORD:"nacos"}

添加nacos配置

比如： dataid = configuration-discovery.default.agentConfigurations group = skywalking 内容：

configurations:
  demo-application:
    agent.trace.ignore_path: "**/actuator/**"

保存以后，在skywalking的控制台会打印如下输出：

Nacos config changed: configuration-discovery.default.agentConfigurations: configurations:
  demo-application:
    agent.trace.ignore_path: "**/actuator/**"

动态配置的用处

比如：可以动态调整需要ignore的endpoint
