PLAYBOOK 命令统计资源利用率 输出本地文件 flask展示

使用 Ansible 统计服务器资源利用率：

3 条 shell 脚本实现统计:

CPU 利用率统计

top -bn1 | grep load | awk '{printf "CPU Load: %.2f ", $(NF-2)}'

内存利用率统计：

free -m | awk 'NR==2{printf "Memory Usage: %s/%sMB (%.2f%%) ", $3,$2,$3*100/$2 }'

磁盘利用率统计（列出每块磁盘利用率）：

df -h -t ext2 -t ext4 | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print "Disk Usage:"" " $1 " " $3"/"$2" ""("$5")"}'

PLAYBOOK 文件编写 将资源利用率输出到 falsk static文件夹内 

from flask import Flask
import os
from flask import make_response
from flask import render_template


app = Flask(__name__)


@app.route('/')
def index():
    APP_ROOT = os.path.dirname(os.path.abspath(__file__))   # refers to application_top
    APP_STATIC = os.path.join(APP_ROOT, 'static')
    with open(os.path.join(APP_STATIC, 'content.html')) as f:response = f.read()
    return response


if __name__ == '__main__':
    app.run(debug=True,host='10.130.130.80',port=5003)
