stats

功能

  • 抓取etcd中 core 和 agent 中的数据，统计信息
  • 透传citadel api中的数据

配置 - 环境变量

  • AGENT_PREFIX etcd中agent的prefix (默认是 /eru-agent)
  • CORE_PREFIX etcd中core的prefix (默认是 /eru-core)
  • CITADEL_URL citadel的地址 (默认是 http://citadel.ricebook.net)
  • CITADEL_AUTH_TOKEN citadel的认证token (默认是 hello)
  • ETCD_ENDPOINTS etcd地址 (默认是本机IP)

接口示例

  • Agent agent中的数据
  • Core core中的数据
    • Containers 容器数量
    • Nodes 节点数量
  • NodesMemcap node的内存对比
    • total node总内存量
    • used_by_memcap 总内存 - 保留内存 - 容器使用内存(core中记录)
    • used node上所有容器统计使用内存 (citadel mysql统计)
    • diff used_by_memcap - used

/diff

{
  "container": {
    "agentLess": [],
    "agentMore": []
  },
  "nodes": {
    "agentLess": [],
    "agentMore": []
  }
}
  • container
    • agentLess agent比core少的container记录
    • agentMore agent比core多的container记录
  • nodes
    • agentLess agent比core少的nodes记录
    • agentMore agent比core多的nodes记录

  • 首项为app的name
  • Entrypoints 中记录app的所有Entrypoint
    • Count Entrypoint部署数量
    • Mem Entrypoint总内存消耗 (bytes)
  • MemTotal | Mem app使用内存量 (bytes | Mb)
  • CPUTotal app使用CPU资源
  • Count app数量
