python脚本用来nagios发送邮件
python脚本用来nagios发送邮件
之前公司nagios发送邮件的脚本是用expect来写的，但是一直有一个弊端就是nagios邮件正文不能换行，只能在一行显示，每次报警看起来都很费劲。一直想换了它，这次用python的脚本就解决的这个换行的问题。
废话少说，上脚本：
[*] #!/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:
[*] only one to emailuser
[*] ./sendmail -t 'eric@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!
[*] many to emailuser
[*] ./sendmail -t 'eric@nginxs.com,zhangsan@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!"""
[*] sys.exit(3)
[*] try:
[*] options,args = getopt.getopt(sys.argv,"ht:s:m:",["help","to=","subject=","message="])
[*] 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 ("-m","--message"):
[*] MESSAGE = value
[*] MESSAGE = MESSAGE.split('\\n')
[*] MESSAGE = '\n'.join(MESSAGE)
[*] #smtp HOST
[*] HOST = "smtp.126.com" #改为你的邮局SMTP 主机地址
[*] #smtp port
[*] PORT = "25" #改为你的邮局的SMTP 端口
[*] #FROM mail user
[*] USER = 'eric' # 改为你的邮箱用户名
[*] #FROM mail password
[*] PASSWD = '123456' # 改为你的邮箱密码
[*] #FROM EMAIL
[*] FROM = "test@163.com" # 改为你的邮箱 email
[*] 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"
使用方法：
只给一个用户发：
nagios $> ./sendmail -t 'test@163.com' -s 'hello' -m 'hello,this is sendmail test!
给多个用户发：
./sendmail -t ' test@163.com,test02@163.com' -s 'hello' -m 'hello,this is sendmail test!
应用到nagios上，用来报警：
# vim /etc/nagios/objects/commands.cfg
define command{
command_name notify-host-by-email
command_line $USER1$/sendmail -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **"-m"***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n"
}
define command{
command_name notify-service-by-email
command_line $USER1$/sendmail -t$CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **"-m"***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$"
}
# /etc/init.d/nagios reload
这样就可以了。
