本文主要研究一下如何将springboot2的metrics输出到influxdb
maven
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-influx</artifactId>
</dependency>
配置
management:
metrics:
export:
influx:
enabled: true
db: springboot
uri: http://192.168.99.100:8086
# user-name:
# password:
connect-timeout: 1s
read-timeout: 10s
auto-create-db: true
step: 1m
num-threads: 2
consistency: one
compressed: true
batch-size: 10000
influx
docker run -d --name influx -p 8086:8086 influxdb
启动之后创建数据库
- 命令行创建
docker exec -it influx influx
create database springboot
- rest接口创建
curl -i -X POST http://192.168.99.100:8086/query --data-urlencode "q=CREATE DATABASE springboot"
返回
HTTP/1.1 200 OK

{"results":[{"statement_id":0}]}
或者直接配置文件指定auto-create-db=true，就无需额外创建

注意这里表名要加引号
- rest接口查看
curl -G 'http://192.168.99.100:8086/query?pretty=true' --data-urlencode "db=springboot" --data-urlencode "q=SELECT \"*\" FROM \"http.server.requests\""
{

"statement_id": 0
}
]
}
小结
springboot2使用micrometer作为metrics组件，其提供了对influxdb的支持，只需要引入micrometer-registry-influx，然后进行配置即可。
