一、配置influxdb
docker run -d -p 8083:8083 -p 8086:8086 --expose 8090 --expose 8099 --name influxsrv tutum/influxdb
默認用戶名：root, 默認密碼：root
# 創建數據庫
create database ‘cadvisor‘;
# 創建用戶
CREATE USER ‘cadvisor‘ WITH PASSWORD ‘cadvisor‘
# 用戶授權
grant all privileges on ‘cadvisor‘ to ‘cadvisor‘
# 授予讀寫權限
grant WRITE on ‘cadvisor‘ to ‘cadvisor‘
grant READ on ‘cadvisor‘ to ‘cadvisor‘
二、cadvisor數據收集，在監控節點啟動
# docker run --volume=/:/rootfs:ro --volume=/var/run:/var/run:rw --volume=/sys:/sys:ro --volume=/var/lib/docker/:/var/lib/docker:ro --volume=/dev/disk/:/dev/disk:ro --publish=9090:8080 --detach=true --name=cadvisor google/cadvisor:latest -storage_driver=influxdb -storage_driver_host=192.168.1.100:8086 -storage_driver_db=cadvisor -storage_driver_user=cadvisor -storage_driver_password=cadvisor
storage_driver=influxdb 指定存儲驅動,使cadvisor將數據存儲到數據庫中，更多存儲插件，請參考這裏
-storage_driver_host=influxdb:8086 InfluxDB數據庫的地址
-storage_driver_db=cadvisor 數據庫名稱
如果要指定用戶名可以用-storage_driver_user參數，默認是root
如果要指定密碼可以用-storage_driver_password參數，默認是root

解決辦法：
# mount -o remount,rw /sys/fs/cgroup/
# ln -sf /sys/fs/cgroup/cpu,cpuacct /sys/fs/cgroup/cpuacct,cpu
二、prometheus配置
docker run -d -p 9090:9090 -v /nfs/prometheus-data/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
配置文件：
global:
scrape_interval: 15s # By default, scrape targets every 15 seconds.
# Attach these labels to any time series or alerts when communicating with
# external systems (federation, remote storage, Alertmanager).
external_labels:
monitor: ‘codelab-monitor‘
# A scrape configuration containing exactly one endpoint to scrape:
# Here it‘s Prometheus itself.
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: ‘prometheus‘
# Override the global default and scrape targets from this job every 5 seconds.
scrape_interval: 5s
static_configs:
- targets: [‘192.168.1.100:9090‘]
三、grafana展示
docker run -d -p 3000:3000 grafana/grafana
