按照以下步骤将Spring Boot中的度量标准发送到Prometheus:
注意:我使用Docker镜像在Mac上本地安装了Prometheus。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
<version>2.0.4.RELEASE</version>
</dependency>
<!-- Micormeter core dependecy -->
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-core</artifactId>
<version>1.0.6</version>
</dependency>
<!-- Micrometer Prometheus registry -->

<version>1.0.6</version>
</dependency>
server.port: 9000 management.server.port: 9001 management.server.address: 127.0.0.1 management.endpoint.metrics.enabled=true management.endpoints.web.exposure.include=* management.endpoint.prometheus.enabled=true management.metrics.export.prometheus.enabled=true
全局配置
global:
scrape_interval: 5s # Set the scrape interval to every 5 seconds.
evaluation_interval: 5s # Evaluate rules every 5 seconds.
scrape_configs:
- job_name: 'hello-world-promethus'
metrics_path: '/actuator/prometheus'
static_configs:
- targets: ['localhost:9001']
当我点击:http://localhost:9001/actuator/prometheus时,我可以看到指标,但它们在Prometheus UI上不可见。
我错过了什么?
解决方案很简单。只有在运行Prometheus Docker Container时才会遇到此问题。将目标从'localhost:9001'更改为'docker.for.mac.localhost:9001'。例如:
- job_name: hello-world-promethus
scrape_interval: 5s
scrape_timeout: 5s
metrics_path: /actuator/prometheus
scheme: http
static_configs:
- targets:
- docker.for.mac.localhost:9001
