篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了提取zabbix监控平台单台服务器图形并发邮件python实现相关的知识,希望对你有一定的参考价值。
需求:希望每天邮件发出当天某台服务器的监控状态,如果某天都登陆zabbix截图很麻烦,而且并不能保证每天都准点操作,于是写了一段脚本实现自动抓取图片,并组装成html,通过定时邮件发送,实现日报自动化。
一、效果图:
二、代码:
#!/usr/bin/env python # -*- coding: utf-8 -*- import mysqldb import datetime import cookielib, urllib2,urllib import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from email.mime.image import MIMEImage #数据库相关信息 dbhost = "服务器IP" dbport = 3306 dbuser = "zabbix登录用户" dbpasswd = "zabbix数据库密码" dbname = "zabbix" #发送邮件配置: receiver = ‘收件人邮箱地址‘ Subject = ‘zabbix监控平台数据‘ smtpserver = ‘smtp.exmail.qq.com‘ mail_username = ‘发送邮箱地址‘ mail_password = ‘密码‘ #查找zabbix的Hostname HostName = "Zabbix server" #查找图像名称 GraphsName = "CPU utilization" #此url是获取图片是的,请注意饼图的URL 和此URL不一样,请仔细观察! gr_url="http://zabbix.XXXX.com/chart2.php" #登陆URL indexURL="http://zabbix.XXXX.com/index.php" username="sunday" password="Aa(2016)" #用于图片存放的目录 image_dir="/tmp/zabbix" class ReportForm: def __init__(self): #打开数据库连接 self.conn = MySQLdb.connect(host=dbhost,user=dbuser,passwd=dbpasswd,db=dbname,port=dbport,charset=‘utf8‘) self.cursor = self.conn.cursor(cursorclass=MySQLdb.cursors.DictCursor) def getGraphID(self,HostName,GraphsName): #获取graphid sql = ‘select distinct graphs_items.graphid from items join graphs_items on graphs_items.itemid=items.itemid join graphs on graphs_items.graphid=graphs.graphid where items.hostid=(select hostid from hosts where host="%s") and graphs.name="%s"‘ % (HostName,GraphsName) if self.cursor.execute(sql): graphid = self.cursor.fetchone()[‘graphid‘] else: graphid = None return graphid def __del__(self): #关闭数据库连接 self.cursor.close() self.conn.close() class ZabbixGraph(object): def __init__(self,url,name,password): self.url=url self.name=name self.password=password #初始化的时候生成cookies cookiejar = cookielib.CookieJar() urlOpener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookiejar)) values = {"name":self.name,‘password‘:self.password,‘autologin‘:1,"enter":‘Sign in‘} data = urllib.urlencode(values) request = urllib2.Request(url, data) try: urlOpener.open(request,timeout=10) self.urlOpener=urlOpener except urllib2.HTTPError, e: print e def GetGraph(self,url,values,image_dir): data=urllib.urlencode(values) request = urllib2.Request(url,data) url = self.urlOpener.open(request) image = url.read() imagename="%s/%s_%s.png" % (image_dir, values["graphid"], values["stime"]) f=open(imagename,‘wb‘) f.write(image) def SendMail(self,receiver,Subject,smtpserver,mail_username,mail_password,values,image_dir,HostName,GraphsName): msgRoot = MIMEMultipart(‘related‘) msgRoot[‘Subject‘] = Subject msgRoot[‘From‘] = mail_username sendText=‘<b>服务器: <i>"%s"</i></b> 提取的图像名称为<b>"%s"</b><br><img src="cid:image1"><br>多谢!‘ % (HostName,GraphsName) msgText = MIMEText(sendText,‘html‘,‘utf-8‘) msgRoot.attach(msgText) sendpng="%s/%s_%s.png" % (image_dir, values["graphid"], values["stime"]) fp = open(sendpng, ‘rb‘) msgImage = MIMEImage(fp.read()) fp.close() msgImage.add_header(‘Content-ID‘, ‘<image1>‘) msgRoot.attach(msgImage) smtp = smtplib.SMTP() smtp.connect(smtpserver) smtp.login(mail_username, mail_password) smtp.sendmail(mail_username, receiver, msgRoot.as_string()) smtp.quit() if __name__ == "__main__": Report = ReportForm() get_graphid=Report.getGraphID(HostName,GraphsName) #图片的参数,该字典至少传入graphid。 stime=datetime.datetime.now().strftime(‘%Y%m%d%H%M%S‘) values={"graphid":get_graphid,"stime":stime,"period":86400,"width":800,"height":200} ZabbixG=ZabbixGraph(indexURL,username,password) ZabbixG.GetGraph(gr_url,values,image_dir) ZabbixG.SendMail(receiver,Subject,smtpserver,mail_username,mail_password,values,image_dir,HostName,GraphsName)
通过以上获取的图片,在组装html,然后使用系统计划任务可实现自动化日报发送。
