prometheus+cadvisor监控docker

官方解释 cAdvisor（ContainerAdvisor）为容器用户提供了对其运行容器的资源使用和性能特性的了解。它是一个正在运行的守护程序，用于收集、聚合、处理和导出有关正在运行的容器的信息。具体来说，它为每个容器保存资源隔离参数、历史资源使用情况、完整历史资源使用的直方图和网络统计信息。该数据按容器和机器范围导出。说白了其实和一般监控的agent类似，就是将容器内部的监控指标持久化存储然后web ui界面展示，结合prometheus+grafana更好的汇聚监控指标 docker部署12345678910111213141516[root@zabbix cadvisor]# cat docker-cadvisor.yml version: "3.5"services: cadvisor: image: harbor.od.com/prometheus/cadvisor:latest container_name: cadvisor volumes: - /:/rootfs:ro - /var/run:/va...
