实验目的 🔗

  1. 创建 easeprobe host probe 配置并运行
  2. 执行内容 在节点 cpu mem disk 负载等达到阈值时发送通知

环境 🔗

验证 🔗

  • 查看日志

  • 查看 8181 端口

  • 由于实验环境为共享容器，物理机负载波动较大，实际表现差距可能很大

  • apk add stress-ng

  • stress-ng -c 1 –vm 15 –timeout 60 –verbose

  • dd if=/dev/zero of=1000m.bin bs=1000MB count=1

问题 🔗

  • 由于环境所在的机器 top 命令与常规不同，所以监测目标为容器
  • apk add procps 安装的 top 输出也不符合 probe 的要求
