python监控linux内存并写入mongodb
（需要安装psutil 用来获取服务器资源，以及pymongo驱动）#pip install psutil
#pip install pymongo
#vim memory_monitory.py
文件内容如下
#!/usr/bin/env python
# -*- coding: UTF-8 -*-
import psutil
import socket
import time
from pymongo import MongoClient
mongodbIp = '192.168.200.112'
mongodbPort = 27017
hostname = socket.gethostbyname(socket.gethostname())#获取本地IP地址
def getCurrentTime():
return time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))
memoryInfo = psutil.virtual_memory()
conn = MongoClient(mongodbIp,mongodbPort)
db = conn.servermonitor
dbset = db.memory
dbset.insert({
'time':getCurrentTime(),
'total':memoryInfo.total,
'available':memoryInfo.available,
'percent':memoryInfo.percent,
'used':memoryInfo.used,
'free':memoryInfo.free,
'active':memoryInfo.active,
'inactive':memoryInfo.inactive,
'buffers':memoryInfo.buffers,
'cached':memoryInfo.cached})
修改文件可以直接执行
#chmod +x memory_monitor.py
使用crontab 定时执行监控程序
#vim vim /etc/crontab
添加如下内容（每分钟执行一次）
*/1 * * * * root /usr/local/memory_monitor.py
