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 getoptdef usage():print """sendmail is a send mail PluginsUsage: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 bodyExample:./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 userTO = valueTO = TO.split(",")if name in ("-s","--title"):SUBJECT = valueif 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-emailcommand_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-emailcommand_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}
