腾讯企业邮箱demo:
# 邮箱配置
xpack.notification.email.account:
mail_account:
profile: standard
email_defaults:
from: xxxxxx@xxxxxx.com
smtp:
auth: true
starttls.enable: true
starttls.required: true
host: smtp.exmail.qq.com # 腾讯企业邮箱
# port: 465 # 配置这个不成功,提示超时
port: 587
user: xxxxxx@xxxxxx.com
使用邮箱客户端密码(不是直接登录的密码,需要邮箱后台获取),添加密码记得切换用户,不然会修改keystore的文件权限,导致es启动失败
sudo -u elasticsearch ./bin/elasticsearch-keystore add xpack.notification.email.account.mail_account.smtp.secure_password
实现告警
需要高级授权
watcher和规则与连接器是两种独立的实现报警的方式,可以参考:https://blog.csdn.net/UbuntuTouch/article/details/118519057
个人感觉规则与连接器这种方式更加灵活,支持的功能更多,也不需要再es的配置文件里面去定义邮箱,可以直接在kibana界面上配置。
