夜了，我却不想睡 写了个监控服务小东西 ， 还需不段完善

修正版本 http://blog.csdn.net/huithe/archive/2010/09/26/5908364.aspx

以插件容易扩展方式，先弄了一个 硬盘空间的监控

[root@ye810 job_monitor]# ls
disk_monitor_plug.py job_monitor.py

模块编写 ： disk_monitor_plug.py

import os,re

#diskinfo_parser = re.compile(r"(.+?)\s+(.+?)\s+(.+?)\s+(?P<Avail>.+?)\s+(?P<Use>.+?)\s+(?P<path>.+?)\s+")
diskinfo_parser = re.compile(r"(?P<Use>(\d)+)%")

def _get_disk_message():
        global diskinfo_parser
        warning_msg = ''

        dp = os.popen("df -lh")
        while True:
                line = dp.readline()
                if not line:
                        break
                info = diskinfo_parser.search(line)
                if(not info):
                        continue
                #print info.group('Use')

                if(int(info.group('Use')) > 90):
                        warning_msg += line
        if(warning_msg):
                print warning_msg

if __name__ == "__main__":
        _get_disk_message()

主程： job_monitor.py

import glob,subprocess
import smtplib

SMTP_address = 'smtp.gmail.com'
SMTP_port = 587

smtp_username = '[e-mail]'
smtp_passwd = 'xxdfwewe'

alerts_mail_address = '[e-mail]'

def mailx(send_mail,recive_mail,mail_content):
        handle = smtplib.SMTP(SMTP_address)
        handle.ehlo()
        handle.starttls()
        handle.ehlo()
        handle.login(smtp_username,smtp_passwd)
        handle.sendmail(send_mail,recive_mail,mail_content)
        handle.quit()




monitor_module_list = glob.glob("*_plug.py")
mail_content = ''

for monitor_module in monitor_module_list:
        thread_handle = subprocess.Popen(args='python '+monitor_module,shell=True,stdout=subprocess.PIPE)
        thread_handle.wait()
        mail_content = thread_handle.stdout.read()

if(mail_content):
        mail_header_format = "From: %s\nTo: %s\nSubject: %s\n\n" % (smtp_username,alerts_mail_address,'Server alerts!!!')
        mail_content_format = mail_header_format + mail_content
        mailx(smtp_username,alerts_mail_address,mail_content_format)

通过邮件形式 发送通知

其他监控内容 CPU 等 。。日后完善
