Python脚本实现发送Zabbix Screen图表邮件

在使用Zabbi x的时候，我们通常会使用Screen图形报表来汇总需要监控的Graph。下面的Python脚本实现了将Screen图形保存到本地，并发送邮件给相关人员的功能。

Zabbix就不多做介绍，下面是脚本代码：

#!/usr/bin/python # -*- coding: utf-8 -*- import os import time import shutil import MySQLdb import smtplib import requests import datetime from email.MIMEText import MIMEText from email.MIMEImage import MIMEImage from email.MIMEMultipart import MIMEMultipart # based on zabbix 2.4.4 ZABBIX_HOST = '127.0.0.1' ZABBIX_USER = 'Admin' ZABBIX_PWD = 'password' ZABBIX_DB_HOST = 'localhost' ZABBIX_DB_USER = 'zabbix' ZABBIX_DB_PWD = 'db_password' ZABBIX_DB_NAME = 'zabbix' GRAPH_PATH = '/tmp/zabbix_graph' GRAPH_PERIOD = 86400  # one day EMAIL_DOMAIN = '163.com' EMAIL_USERNAME = 'wuxianglong098' EMAIL_PASSWORD = 'email_password' def query_screens(screen_name):  conn = MySQLdb.connect(host=ZABBIX_DB_HOST, user=ZABBIX_DB_USER, passwd=ZABBIX_DB_PWD,          db=ZABBIX_DB_NAME, charset='utf8', connect_timeout=20)  cur = conn.cursor()  count = cur.execute("""    select a.name, a.screenid, b.resourceid, b.width, b.height     from screens a, screens_items as b     where a.screenid=b.screenid and a.templateid<=>NULL and a.name='%s'     order by a.screenid;    """ % screen_name)  if count == 0:   result = 0  else:   result = cur.fetchall()  cur.close()  conn.close()  return result def generate_graphs(screens):  login_resp = requests.post('http://%s/index.php' % ZABBIX_HOST, data={   'name': ZABBIX_USER,   'password': ZABBIX_PWD,   'enter': 'Sign in',   'autologin': 1,  })  session_id = login_resp.cookies['zbx_sessionid']  graphs = []  for i, (screen_name, screen_id, graph_id, width, height) in enumerate(screens):   params = {    'screenid': screen_id,    'graphid': graph_id,    'width': width * 2,    'height': height * 2,    'period': GRAPH_PERIOD,    'stime': datetime.datetime.utcnow().strftime('%Y%m%d%H%M%S'),   }   resp = requests.get('http://%s/chart2.php' % ZABBIX_HOST, params=params,        cookies={'zbx_sessionid': session_id})   file_name = '_'.join(map(str, screens[i][:3])).replace(' ', '_') + '.png'   with open(os.path.join(GRAPH_PATH, file_name), 'wb') as fp:    fp.write(resp.content)   graphs.append(file_name)  return graphs def send_mail(screen_name, graphs, to_list):  me = 'Zabbix <%s@%s>' % (EMAIL_USERNAME, EMAIL_DOMAIN)  def _create_msg():   msg = MIMEMultipart('related')   msg['Subject'] = 'Zabbix Screen Report: %s' % screen_name   msg['From'] = me   msg['To'] = ';'.join(to_list)   msg.preamble = 'This is a multi-part message in MIME format.'   contents = "<h1>Screen %s</h1><br>" % screen_name   contents += "<table>"   for g_name in graphs:    with open(os.path.join(GRAPH_PATH, g_name), 'rb') as fp:     msg_image = MIMEImage(fp.read())     msg_image.add_header('Content-ID', "<%s>" % g_name)     msg.attach(msg_image)    contents += ''    contents += "<tr><td><img src='cid:%s'></td></tr>" % g_name   contents += "</table>"   msg_text = MIMEText(contents, 'html')   msg_alternative = MIMEMultipart('alternative')   msg_alternative.attach(msg_text)   msg.attach(msg_alternative)   return msg  try:   server = smtplib.SMTP()   server.connect('smtp.%s' % EMAIL_DOMAIN)   server.login('%s@%s' % (EMAIL_USERNAME, EMAIL_DOMAIN), EMAIL_PASSWORD)   server.sendmail(me, to_list, _create_msg().as_string())   server.close()   print 'send mail Ok!'  except Exception, e:   print e if __name__ == '__main__':  # remove old dirs  if os.path.exists(GRAPH_PATH):   shutil.rmtree(GRAPH_PATH)  os.makedirs(GRAPH_PATH)  for srn_name in (u'Zabbix server', u'Nginx Connections'):   # get screens   all_screens = query_screens(srn_name)   print all_screens   # generate graphs   graphs = generate_graphs(all_screens)   send_mail(srn_name, graphs, ['wuxianglong098@163.com'])
