最近研究了prometheus+grafana的系统监控，使用grafana的报警功能，grafana支持很多种通知渠道，下文记录使用到的几种notification channels，分别是email,kafka和webhook
官网文档 http://docs.grafana.org/alerting/notifications/
- 发送邮件
修改smtp,找到%GRAFANA_HOME%/conf/defaults.ini(注windows环境)
[smtp] enabled = true #开户email发送配置 host = smtp.xxx.com:25 #此处需要加上端口号 user =username@xxx.com #邮箱账号 # If the password contains # or ; you have to wrap it with triple quotes. Ex """#password;""" password =1234567890 #邮箱密码 cert_file = key_file = skip_verify = true #跳过校验 from_address = [email protected] from_name = Grafana ehlo_identity =
- kafka
向kafka发送消息，需要kafka REST proxy，我使用的中间件是confluent，安装过程没什么特别之外，配置（confluent_home/etc/kafka-rest/kafka-rest.properties）如下
#id=kafka-rest-test-server #schema.registry.url=http://localhost:8081 #zookeeper.connect=localhost:2181 #bootstrap.servers=PLAINTEXT://localhost:9092 zookeeper.connect=xx.xx.xx.xx:2181 bootstrap.servers=PLAINTEXT://xx.xx.xx.xx:9092
启用kafka-rest服务
bin/kafka-rest-start ../etc/kafka-rest/kafka-rest.properties
添加notification channels
点击 “send test”按钮，浏览kafka-rest服务，alert-gateway-test-1已经在kafka topic里了，开发者可消费kafka的消息，进行后续（自定义）处理
- webhook(推荐）
回调参数
{
"title": "My alert",
"ruleId": 1,
"ruleName": "Load peaking!",
"ruleUrl": "http://url.to.grafana/db/dashboard/my_dashboard?panelId=2",
"state": "alerting",
"imageUrl": "http://s3.image.url",
"message": "Load is peaking. Make sure the traffic is real and spin up more webfronts",
"evalMatches": [
{
"metric": "requests",
"tags": {},
"value": 122
}
]
}
