用logstash发邮件告警

来源：互联网发布：知乎教育幼儿书编辑：程序博客网时间：2024/05/21 16:39

logstash input http

该输入插件会让logstash在一个端口上监听http请求，用户可以通过http请求发送告警请求。

input {    http {        host => "0.0.0.0"        port => 9500        type => "heartbeat"        user => "loguser"        password => "logpwd"        #codec => json{}    }}

如果设置了user,password，则发送http请求时需要Auth Basic验证
如果http请求header包含：Content-Type: application/json，则http插件将自动调用codec json将输入内容解析成json格式
发送请求：

POST http://localhost:9500{  "appid": "app_heaertbead_monit",  "to": "jiaofuyou@qq.com",  "subject": "heaertbead monit",  "body": "heaertbead monit body"}

logstash output email

output {    if [type] == "heartbeat" {        email {            to => "%{to}"            from => "from@qq.com"            address => "smtp.qq.com"            username => "username "            password => "password "            subject => "%{subject}"            body => "%{body}"            htmlbody => ""        }    }    #同时也经redis再保存到elasticsearch中    redis {        host => '172.16.18.116'        data_type => 'list'        key => 'logstash:redis'    }}
