docker监控

采用prometheus和grafana监控
安装Noderexporter和Cadvisor

docker stop cadvisor
docker rm cadvisor
sudo docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:rw \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--publish=8081:8080 \
--detach=true \
--name=cadvisor \
docker.io/google/cadvisor
docker stop nodeexporter
docker rm nodeexporter
docker run -d -p 9100:9100 \
  -v "/proc:/host/proc:ro" \
  -v "/sys:/host/sys:ro" \
  -v "/:/rootfs:ro" \
  --net="host" \
  quay.io/prometheus/node-exporter
docker stop prometheus
docker rm prometheus
docker run -itd -p 9090:9090 \
-v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml \
-v /opt/prometheus/prometheus-data:/prometheus \
-v /etc/localtime:/etc/localtime:ro \
--privileged=true \
--restart always \
--name=prometheus \
docker.io/prom/prometheus

配置

# my global config

  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).
# Alertmanager configuration

解决问题

1.cadvisor无法映射路径的问题
sudo mount -o remount,rw '/sys/fs/cgroup'
sudo ln -s /sys/fs/cgroup/cpu,cpuacct /sys/fs/cgroup/cpuacct,cpu
2.导入模板无法显示的问题
添加数据源的时候要注意：将Prometheus的p大写！
