python插件做nagios发报警邮件<二>

接上文 python插件做nagios发报警邮件 http://www.nginxs.com/linux/371.html，由于python 传入的参数，python 会自动加 \ ，经过代码测试，代码如下：

nagios $> cat test.py

#!/usr/bin/python

import sys

str = sys.argv[1]

str = repr(str)

print str

nagios $> python test.py “aaaa\nfffff”

‘aaaa\\nfffff’

测试过很多方法，都不行，最后用了最笨的的方法就是读文件！就稍微改动了一下上文脚本

nagios $> cat /usr/local/nagios/libexec/sendmail

#!/usr/bin/python
import smtplib
import string
import sys
import getopt

def usage():
print """sendmail is a send mail Plugins
Usage:

sendmail [-h|--help][-t|--to][-s|--subject][-m|--message]

Options:
--help|-h)
print sendmail help.
--to|-t)
Sets sendmail to email.
--subject|-s)
Sets the mail subject.
--message|-m)
Sets the mail body
Example:
./sendmail -t 'eric@nginxs.com' -s 'hello eric' -p /tmp/nagios-mail '"""

sys.exit(3)

try:
options,args = getopt.getopt(sys.argv[1:],"ht:s:p:",["--help","--to=","--subject=","--path="])
except getopt.GetoptError:
usage()
for name,value in options:
if name in ("-h","--help"):
usage()
if name in ("-t","--to"):
# accept message user
TO = value
TO = TO.split(",")
if name in ("-s","--title"):
SUBJECT = value
if name in ("-p","--path"):
MESSAGE = value                     #传入文件路径
MESSAGE = open(MESSAGE,'r')    #只读模式打开文件
MESSAGE = MESSAGE.read()       #读取文件内容
#smtp HOST
HOST = "smtp.126.com"
#smtp port
PORT = "25"
#FROM mail user
USER = 'eric'
#FROM mail password
PASSWD = '123456'
#FROM EMAIL
FROM = "yangzi2008@126.com"

try:
BODY = string.join((
"From: %s" % FROM,
"To: %s" % TO,
"Subject: %s" % SUBJECT,
"",
MESSAGE),"\r\n")

smtp = smtplib.SMTP()
smtp.connect(HOST,PORT)
smtp.login(USER,PASSWD)
smtp.sendmail(FROM,TO,BODY)
smtp.quit()
except:
print "UNKNOWN ERROR"
print "please look help"
print "./sendmail -h"

注意：

改动了 message 以读文件内容方式传入，放弃了以参数方法传入。

-m 擦数改为 -p参数 -p 后面 跟 文件的 绝对路径。

修改 nagios 的 commands.cfg

nagios $> vim /usr/local/nagios/etc/objects/commands.cfg
define command{
command_name    notify-host-by-email
command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" > /tmp/nagios-mail | $USER1$/sendmail -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" -p /tmp/nagios-mail
}

define command{
command_name    notify-service-by-email
command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" > /tmp/nagios-mail| $USER1$/sendmail -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" -p /tmp/nagios-mail
}
