0d44a42e10dc busybox1 0.00% 56KiB / 3.686GiB 0.00% 1.09kB / 0B 1.18MB / 0B 1
字段含义
container id容器id
name容器名字
CPU %CPU使用百分比
MEM USAGE/limit容器使用的总内存以及它允许使用的总内存
mem%内存使用百分比
net I/O容器通过其网络接口接收和发送的数据量
block I/O容器从主机上的块设备写入和读取的数据量
pids容器已经创建的进程或线程的数量
选项
-a显示所有容器(默认显示正在运行)
--no-stream禁用流统计只拉取第一个结果
--no-trunc不截断输出 2.weave scope
weave scope 的最大的特点就是会自动生成一张docker容器地图让我们能够直观的理解监控和控制器。
1.下载
wget https://github.com/weaveworks/scope/releases/download/v1.13.2/scope
2.安装
[rootlocalhost ~]# chmod x scope
[rootlocalhost ~]# ./scope launch

3.访问查询即可
http://192.168.2.5:4040/ 3.Prometheus监控平台
1.部署数据收集器cadvisor
[rootlocalhost ~]# docker run -v /:/rootfs:ro -v /var/run/:/var/run/:rw -v /sys:/sys:ro -v /var/lib/docker:/var/lib/docker:ro -p 8080:8080 -d --name cadivsor google/cadvisor
访问http://192.168.2.5:8080/containers/ 2.部署Prometheus
[rootlocalhost ~]# docker run -d -p 9100:9100 \
-v /proc:/host/proc \
-v /sys:/host/sys \
-v /:/rootfs \
--nethost \
prom/node-exporter \
--path.procfs /host/proc \
--path.sysfs /host/sys \
--collector.filesystem.ignored-mount-points ^/(sys|proc|dev|host|etc|rootfs/var/lib/docker/containers|rootfs/var/lib/docker/overlay2|rootfs/run/docker/netns|rootfs/var/lib/docker/devicemapper|rootfs/var/lib/docker/aufs)($$|/)

编写Prometheus监控配置文件
[rootlocalhost ~]# vi prometheus.yml
# my global config
global:scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.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
alerting:alertmanagers:- static_configs:- targets:# - alertmanager:9093
# Load rules once and periodically evaluate them according to the global evaluation_interval.
rule_files:# - first_rules.yml# - second_rules.yml
# A scrape configuration containing exactly one endpoint to scrape:
# Here its Prometheus itself.
scrape_configs:# The job name is added as a label jobjob_name to any timeseries scraped from this config.- job_name: prometheus
# metrics_path defaults to /metrics# scheme defaults to http.
static_configs:- targets: [localhost:9090,localhost:8080,localhost:9100]
主要配置文件内容 static_configs:- targets: [localhost:9090,localhost:8080,localhost:9100]
注意填写你需要监控的cadvisor的IP地址和端口号
3.部署可视化平台Gragana
[rootlocalhost ~]# docker run -d -i -p 3000:3000 \
-e GF_SERVER_ROOT_URLhttp://grafana.server.name \
-e GF_SECURITY_ADMIN_PASSWORDsecret \
--nethost \
grafana/grafana
4.进入后台控制台
http://192.168.2.5:3000/
默认用户名和密码
admin
密码GF_SECURITY_ADMIN_PASSWORDsecret字段内容
注意如果不指定密码为admin
1.添加Prometheus模块 2.添加docker容器监控模板
docker容器模板193
Linux主机监控模板9276 监控结果
