Zabbix通过邮件发送Screen图形报表实现
在使用Zabbix的过程中，我们通常会建立一些需要的Screen图形报表来汇总需要监控的Graph。而下面的两个脚本，则是通过从Zabbix数据库中获取所有的Screen图形参数，提供Zabbix的WEB接口将所有图形保存到本地，然后通过脚本以Email形式发送过来，作为每天的自动报表。
$ sudo mkdir -p /data/script
$ sudo mkdir -p /data/graph
$ sudo vim /data/scripts/save-graph.pl
#!/usr/bin/perl
use File::Path;
use DBI;
my $path = '/data/graph';
if(-e $path) { rmtree($path); }
mkdir($path);
my $stime = `date +%Y%m%d`; chop($stime); $stime .= '1000';
if( length($stime) != 12 ) { print "Error get date"; exit; }
my $period = 86400; # 24 hours
my $login = 'admin';# Zabbix Web User
my $pass = 'password'; # Zabbix Web User Password, must be URL Encoded
my $cook = "/tmp/cookie";
my $dsn = 'DBI:mysql:zabbix:localhost'; # Connect MySQL DB "zabbix" on localhost
my $db_user_name = 'zabbix'; # MySQL DB user
my $db_password = 'dbpassword'; # MySQL DB user password
my $dbh = DBI->connect($dsn, $db_user_name, $db_password);
my $sth = $dbh->prepare(qq{select a.name,a.hsize,a.vsize, b.resourceid, b.width, b.height,b.x,b.y from screens a,screens_items as b where a.screenid=b.screenid and a.templateid<=>NULL order by a.name});
$sth->execute();
my %screens;
# Get all graphs by using curl
while (my ($name,$hsize,$vsize, $id,$width,$height,$x,$y) = $sth->fetchrow_array())
{
if(length($id) > 2){
#print "$id => $ids\n";
my $p = "$path/$name.$hsize.$vsize.$y.$x.$id.png";
my $strcomm= `curl-c $cook -b $cook -d "request=&name=$login&password=$pass&autologin=1&enter=Sign+in"localhost/zabbix/index.php`;
$strcomm= `curl-b $cook -F"graphid=$id" -F "period=$period" -F "stime=$stime" -F "width=$width" -F "height=$height" localhost/zabbix/chart2.php > $p`;
}
}
exit ;
$ sudo vim email-pic.py
#! /usr/bin/env python
import os
import smtplib
from email.MIMEMultipart import MIMEMultipart

def _get_pictures(image_dir):

for f in os.listdir(image_dir):
pictures.append(f)
return pictures
def _create_msg(screen_name,screens,image_dir,str_from,list_to):
msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = 'Zabbix Screen Report: %s' % screen_name
msgRoot['From'] = str_from
msgRoot['To'] = ",".join(list_to)
msgRoot.preamble = 'This is a multi-part message in MIME format.'
# Encapsulate the plain and HTML versions of the message body in an
# 'alternative' part, so message agents can decide which they want to display.
msgAlternative = MIMEMultipart('alternative')
msgRoot.attach(msgAlternative)
msgText = MIMEText('This is the alternative plain text message.')
msgAlternative.attach(msgText)
contents = ""
contents += "<h1>Screen %s</h1><br>" % screen_name

screens = sorted(screens)
y= -1
for f in screens:
items = f.split('.')
_,_,_,image_y,image_x,image_id,_ = tuple(items)
image_name = "image-%s-%s" % (screen_name, image_id)
fp = open('%s/%s' % (image_dir,f), 'rb')
msgImage = MIMEImage(fp.read())
fp.close()
msgImage.add_header('Content-ID', "<%s>" % image_name)
msgRoot.attach(msgImage)
if y != image_y:
if y!= -1:

msgText = MIMEText(contents, 'html')

return msgRoot
# Create the root message and fill in the from, to, and subject headers
def main(str_from,list_to,image_dir):
pictures = _get_pictures(image_dir)
for screen_name in list(set( for x in pictures ])):
screens =
msgRoot = _create_msg(screen_name,screens,image_dir,str_from,list_to)
_sendmail('smtp.example.com',25,'username','password',str_from,list_to,msgRoot.as_string())
if __name__ == '__main__':
str_from = 'username@example.com'
list_to = [
"jack@example.com", "tom@example.com", "jim@example.com"
]
image_dir = '/data/graph'
main(str_from,list_to,image_dir)
接着，将这两个脚本加入到crontab中定时执行。
$ sudo crontab -e
30 23 * * * /data/script/save-graph.pl
55 23 * * * /data/script/email-pic.py
这样，就可以收到对应的Zabbix图形邮件报表了，如下图所示：
-------------------------------分割线-------------------------------
1、按周显示：
my $period = 86400; 这里就是用来定义时间的，以秒为单位。
2、执行python时出错，麻烦帮助看一下。python2.6\2.7版本都试过
Traceback (most recent call last):
File "./email-pic.py", line 80, in
main(str_from,list_to,image_dir)
File "./email-pic.py", line 71, in main
msgRoot = _create_msg(screen_name,screens,image_dir,str_from,list_to)
File "./email-pic.py", line 41, in _create_msg
_,hsize,vsize,_,_,_,_,= tuple(screens.split('.'))
IndexError: list index out of range
必须和上面的脚本和步骤配合使用，完成的任务其实就是，创建目录，利用Zabbix接口生成好好图片，然后通过邮件发送。
