linux：使用python腳本監控某個進程是否存在（不使用crontab）

背景：

　　需要每天定時去檢測crontab進程是否啟動，所以不能用crontab來啟動檢測腳本了，直接使用while 循環和sleep方式實現定時檢測

# coding:utf-8
import os
import send_message
import datetime
import timecurr_time = datetime.datetime.now()
time_str = datetime.datetime.strftime(curr_time,'%H:%M:%S')def loopMonitor():curr_time = datetime.datetime.now()time_str = datetime.datetime.strftime(curr_time,'%H:%M')if time_str == '08:05':print 'come in already'check_process()return#2s檢查一次time.sleep(60)loopMonitor()def check_process():process="./cron.lock"os.system("ps -ef|grep python3|grep -v grep >%s" % process)if not(os.path.getsize(process)):send_message.send_message('crontab not running', [8618320120156])else:f=open('./cron.lock', "r+")f.truncate()if __name__ == '__main__':loopMonitor()
