web界面获取组件信息转圈3~5s显示问题分析
更新时间： 2026/05/28
在Gitcode上查看源码

问题背景 ​

  • 单板类型：NA
  • 软件版本：NA
  • 涉及功能：组件信息显示。
  • 触发条件：调用curl命令来获取智能网卡温度，导致web界面卡顿。
  • 业务表现：预期web页面流畅显示内容；实际web界面获取组件信息转圈3~5s显示。

问题复现步骤 ​

  1. 调用skynet fork线程去获取智能网卡温度，获取方式是通过curl命令curl.easy_perform调用redfish url来获取智能网卡温度。

  1. web界面获取组件信息，一直在转圈3~5s之后才显示出来信息。

关键日志信息 ​

使用worker获取不同组件的温度，3s超时一次，循环获取：

定位过程 ​

  • 调用skynet fork执行获取智能网卡温度，获取智能网卡温度流程会有3~5s卡顿

  • 获取智能网卡温度需要使用curl命令，发现curl.easy_perform是串行阻塞的，参考指导：worker_core 后台工作线程库 | openUBMC。

问题原因 ​

调用阻塞性API的C库会导致进程下的资源树访问阻塞、组件心跳丢失的情况。

解决方案 ​

需要使用框架提供的worker库，创建worker线程，将阻塞操作在worker线程中执行。

注意：local w = worker.new(0)要定义为全局变量，避免出现使用worker_core执行获取智能网卡温度curl动作之后，还是出现属性获取失败，web卡顿问题。
