又一个ansible例子

这个例子有点复杂，他在被控端上采集CPU 内存和磁盘利用率，并且以模板的形式保存在被控端，最后再把这个结果文件从被控端取回来。综合用到了shell、register、template和fetch4个模块

---

• name: get cpu mem and disk

hosts: all

tasks:

• name: get cpu

shell:

cmd: top -bn 1 | grep Cpu | awk '{print $2+$3}'

register: mycpu

• name: get mem

shell:

cmd: free | grep Mem | awk '{print $3/$2}'

register: mymem

• name: get disk

shell:

cmd: df / | grep / | awk '{print $5}'

register: mydisk

• name: output template

template:

src: /root/result.j2

dest: /root/result.txt

• name: fetch result

fetch:

src: /root/result.txt

dest: /root/

flat: yes

模板文件如下：

more result.j2

cpu useage: {{mycpu.stdout}}

mem useage: {{mymem.stdout}}

disk useage: {{mydisk.stdout}}
