Zabbix通过邮件发送Screen图形报表实现

[日期:2013-06-10] 来源:heylinux.com  作者:mcsrainbow [字体: ]

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
from email.MIMEText import MIMEText
from email.MIMEImage import MIMEImage

def _sendmail(smtp_server,port,account,password,str_from,list_to,msg):
    smtp = smtplib.SMTP(smtp_server,port)
    smtp.ehlo()
    smtp.starttls()
    smtp.ehlo()
    smtp.login(account, password)
    smtp.sendmail(str_from, list_to,msg)
    smtp.close()

def _get_pictures(image_dir):
    pictures = []
    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
    _,hsize,vsize,_,_,_,_,= tuple(screens[0].split('.'))
    contents +="<table>"
    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:
                contents +="</tr>"
            y = image_y
            contents +="<tr>"
        contents +="<td><img src='cid:%s'></td>" % image_name
    contents += "</table>"
    msgText = MIMEText(contents, 'html')
    msgAlternative.attach(msgText)
    msgRoot.attach(msgAlternative)
    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([x.split('.')[0] for x in pictures ])):
        screens = [x for x in pictures if x.startswith(str(screen_name) + '.') ]
        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[0].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。

你好,楼主。运行save-graph.pl脚本,出现以下错误,不知什么原因,麻烦请教
curl: (6) Couldn't resolve host 'server.4.2.1.3.525.png'
