配置 Couchbase 监控

编辑配置文件

编辑配置文件 conf.d/couchbase.yaml，使 Cloud Insight Agent 可以与 Couchbase 通信。

init_config:

instances:
  - server: http://localhost:8091
    user: Administrator
    password: password
    tags:
      - tag_key:tag_value

重启 Agent

重启 OneAPM Cloud Insight Agent，使配置生效。

您也可以通过查看 Agent Info 信息，来验证配置是否成功。当出现以下信息，则代表安装成功。
