配置文件
spring:
application:
name: springbootPrometheusGrafana
management:
endpoints:
web:
exposure:
include: '*'
metrics:
tags:
application: ${spring.application.name}
如果使用properties
spring.application.name=springbootPrometheusGrafana
management.endpoints.web.exposure.include=*
management.metrics.tags.application=${spring.application.name}
实例化MeterRegistryCustomizer
方便起见，我们就在启动类中实例化吧
package com.artisan;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import io.micrometer.core.instrument.MeterRegistry;
@SpringBootApplication
public class SpringbootPrometheusGrafanaApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootPrometheusGrafanaApplication.class, args);
}
@Bean
MeterRegistryCustomizer<MeterRegistry> configurer(@Value("${spring.application.name}") String applicationName) {
return (registry) -> registry.config().commonTags("application", applicationName);
}
}
打包，上传到服务器上
右键–Run As – Maven build ,输入 clean package
服务器上启动该jar即可
java -jar springbootPrometheusGrafana-0.0.1-SNAPSHOT.jar &
Prometheus 修改配置文件prometheus.yml 接入该工程
增加如下配置：
#SpringBoot应用配置
- job_name: 'springbootPrometheusGrafana'
scrape_interval: 5s
metrics_path: '/actuator/prometheus'
static_configs:
- targets: ['192.168.31.34:8080']
重启Prometheus
[root@artisan prometheus]# ./prometheus --config.file=prometheus.yml &

Grafana 组件
官网：https://grafana.com/
下载地址： https://grafana.com/grafana/download
入门：http://docs.grafana.org/guides/getting_started/
刚才也说了，Prometheus 的可视化功能比较弱，这里我们来接入Grafana 。
Grafana是一个跨平台的开源的度量分析和可视化工具，可以通过将采集的数据查询然后可视化的展示，并及时通知。它主要有以下六大特点：
-
展示方式：快速灵活的客户端图表，面板插件有许多不同方式的可视化指标和日志，官方库中具有丰富的仪表盘插件，比如热图、折线图、图表等多种展示方式；
-
数据源：Graphite，InfluxDB，OpenTSDB，Prometheus，Elasticsearch，CloudWatch和KairosDB等；
-
通知提醒：以可视方式定义最重要指标的警报规则，Grafana将不断计算并发送通知，在数据达到阈值时通过Slack、PagerDuty等获得通知；
-
混合展示：在同一图表中混合使用不同的数据源，可以基于每个查询指定数据源，甚至自定义数据源；
-
注释：使用来自不同数据源的丰富事件注释图表，将鼠标悬停在事件上会显示完整的事件元数据和标记；
-
过滤器：Ad-hoc过滤器允许动态创建新的键/值过滤器，这些过滤器会自动应用于使用该数据源的所有查询。
