Monitor linux memory using python and write it to mongodb

This article mainly introduces the relevant information about python monitoring Linux memory and writing to mongodb. Friends who need it can refer to

(psutil needs to be installed to obtain server resources and pymongo driver) #pip install psutil

##

#pip install pymongo
#vim memory_monitory.py

The content of the file is as follows

#!/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})

You can modify the file and execute it directly

#chmod +x memory_monitor.py

Use crontab to execute the monitoring program regularly

#vim vim /etc/crontab

Add the following content (execute once every minute)

*/1 * * * * root /usr/local/memory_monitor.py
#service crond reload  //重新载入配置
#service crond restart //重启服务
