python插件做nagios发报警邮件
Ps: 完美的解决了python传入参数带有回车换行符，不换行问题。修改本文时间：2010年12月21号，脚本有变动·nagios commands.cfg无需修改·用了此版本·就解决了不用去读文本方式。安装好nagios后，一直利用nagios服务器上的sendmail服务器去发邮件，修改配置文件可以伪造别的邮件地址发邮件，但是一直会被邮局视为垃圾邮件，我把email地址加在了QQ上，好处是一来邮件QQ右下角会弹提示。工作时间会第一时间知道服务器出状况（手机短信暂时不提），但是如果是垃圾邮件，QQ不会提醒的，当然可以在QQ邮箱把其添加为信任邮局，可以避免。我就不那么浪费时间了。自己写一个发邮件的插件来替换掉本机的sendmail服务，可以为服务器节省资源，大家也知道启动sendmail服务稍稍费点时间，如果主机名没有设置好的话sendmail服务会启动很久才能起来的哦。废话不多说了，发源代码。
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:
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,yangzi@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 = "yangzi2008@126.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 'eric@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!
给多个用户发：
./sendmail -t 'eric@nginxs.com,yangzi@nginxs.com,zhangsan@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!
如果利用在nagios 上修改 commands.cfg
# 还为测试·马上就测试。怕的是换行符有问题·
nagios $> vim /usr/local/nagios/etc/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$SERVICEOUTPUT$"
}
