mail 發送 zabbix（4.1） 監控圖 （流量日報）

思路：找到zabbix圖片的url，分析url，讀取內容生成圖片，郵件發送

1、找到zabbix中該圖形，然後 右擊圖形 複製圖片地址鏈接，下面爲 事例

http://10.0.13.104/zabbix/chart2.php?graphid=26962&from=2019-06-19+00%3A00%3A00&to=2019-06-19+15%3A00%3A00&profileIdx=web.graphs.filter&profileIdx2=26962&width=954&_=tp3dh98k&screenid=

簡單分析一下這個url的各個參數：

chart2.php  輸出頁面

graphid=26962 圖形的id

from=2019-06-19+00%3A00%3A00 圖形範圍選擇的開始時間

to=2019-06-19+15%3A00%3A00 圖形範圍選擇的結束時間

profileIdx=web.graphs.filter

profileIdx2=26962 和圖形的id一樣

width=954 圖形寬度

提取以上信息，需要參數爲 1、輸出頁面；2、圖形id；3、範圍時間；4、圖形寬度

2、python腳本事例

    def getGraphID(self,HostName,GraphsName):
        graphid = 26962
        return graphid
 
class ZabbixGraph(object):
    def __init__(self,url,name,password):
        self.url=url
        self.name=name
        self.password=password
		#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)

        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'] = ("%s <mail@mail>")%(Header('流量發送','utf-8'))
        msgRoot['to'] = ','.join(receiver) 
        sendText='<b><br /><fontsize="20">昨日帶寬<br /><br><img src="cid:image1"><br /><br /><fontsize="20">最近7天帶寬<br /><br><img src="cid:image2">'
        msgText = MIMEText(sendText,'html','utf-8')
        msgRoot.attach(msgText)
        sendpng="%s/%s_%s.png" % (image_dir, values["graphid"], values["from1"])
        fp = open(sendpng, 'rb')
        msgImage = MIMEImage(fp.read())
        fp.close()
        sendpng2="%s/%s_%s.png" % (image_dir, values["graphid"], values["from7"])
        fp2 = open(sendpng2, 'rb')
        msgImage2 = MIMEImage(fp2.read())
        fp2.close()
        msgImage.add_header('Content-ID', '<image1>')
        msgImage2.add_header('Content-ID', '<image2>')
        msgRoot.attach(msgImage)
        msgRoot.attach(msgImage2)
        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)
    #zabbix 圖形 graphid
    #print(get_graphid)
    stime=datetime.datetime.now().strftime('%Y%m%d%H%M%S')
    from1='now-24h'
    to='now'
    profileIdx='web.graphs.filter'
    profileIdx2='26962'
    from7='now-7d'
    values={"profileIdx":profileIdx,"profileIdx2":profileIdx2,"graphid":get_graphid,"from":from1,"to":to,"period":86400,"width":700,"height":150,"stime":stime}
    values2={"profileIdx":profileIdx,"profileIdx2":profileIdx2,"graphid":get_graphid,"from":from7,"to":to,"period":86400,"width":700,"height":150,"stime":stime}
    ZabbixG=ZabbixGraph(indexURL,username,password)
    ZabbixG.GetGraph(gr_url,values,image_dir)
    ZabbixG.GetGraph(gr_url,values2,image_dir)
    values={"graphid":get_graphid,"from1":from1,"to":to,"from7":from7}
    ZabbixG.SendMail(receiver,Subject,smtpserver,mail_username,mail_password,values,image_dir,HostName,GraphsName)

3、本來腳本爲 只發送昨日帶寬圖， 後又添加了最近7天的圖片，所以腳本中出現時間有2個

    from1='now-24h'
    to='now'
    profileIdx='web.graphs.filter'
    profileIdx2='26962'
    from7='now-7d'

4、注意圖片生成位置 及權限， 圖片生成名稱每天一樣 節省刪除時間，有需要保存的可 更改生成圖片名稱。
