docker基础之八monitor-3-weavescope

weave scope

所用镜像
weaveworks/scope:1.11.5

Weave Scope 的最大特点是会自动生成一张 Docker 容器地图，让我们能够直观地理解、监控和控制容器。千言万语不及一张图

安装

curl -L git.io/scope -o /usr/local/bin/scope

chmod a+x /usr/local/bin/scope

[root@nas5 ~]# scope launch
69ebf839c7da58718415464bb11e95cf3b5b85bdd6e3d41d77b0f42c148af1dc
Scope probe started
Weave Scope is listening at the following URL(s):
  * http://10.100.4.105:4040/
  * http://10.1.1.15:4040/

scope launch 将以容器方式启动 Weave Scope。

[root@nas5 ~]# docker ps -a

容器监控

weave scope地图中间显示了host当前运行的容器，不过少了weave相关的容器

weave scope将容器分为两类：weave自己的容器system container,和其它容器application container,默认仅显示后者

weavescope界面可交互的，点击地图左下角的All可显示所有container

点击cpu选择器，weave scope将以高低水位方式显示容器CPU使用量

如果此时将鼠标放到容器图标，则会显示具体的CPU%

点击容器图标，可以查看容器详细信息

详细信息包括：

Status

Info

Inbond

Outbond

Processes

Docker labels

Image

对容器的操作按钮

docker container attach

docker container exec

docker container restart

docker container pause

docker container stop

Hosts监控

点击顶部Hosts菜单项，地图将显示当前host

与容器类似，点击host图标将显示详细信息

host当前的资源使用情况和历史曲线一览无余

host页面上部有一个按钮，可以直接打开host的shell窗口，进行远程远程管理

多主机监控

在同时需要监控的两台主机上都运行
