springboot1.x+promethus+grafana打造分布式监控系统

客户端集成prothmethus 端点

目前的环境是：

springboot-1.5.9.RELEASE
promethus 2.18.1
grafana6.0.0

加入promethus依赖

加入配置文件

@Configuration

public class MicrometerConfiguration {



    @Value("${spring.application.name}")

    private String applicationName;



    @Bean

    MeterRegistryCustomizer meterRegistryCustomizer(MeterRegistry meterRegistry) {

        return meterRegistry1 -> {

            meterRegistry.config()

                    .commonTags("application", StringUtils.isEmpty(applicationName)?"sample-applicaton"

                            :applicationName);

        };

    }
}

修改yml文件或properties文件

management:

  security:

    enabled: false

spring:

  application:

    name: springboot-sample

启动项目

完成项目启动后，可以在控制台->endpoints->mappings中看到暴露的promethus端点

安装prothmethus

windows 安装prothmethus

下载prothmethus windows安装包，官网地址

https://prometheus.io/download/

目前使用的版本是prometheus-2.18.1.windows-amd64

配置promethus

下载完成安装包后，加压在任何位置，修改prometheus.yml文件主要修改的部分是标红的部分

# my global config

global:

  scrape_interval:     10s # Set the scrape interval to every 15 seconds. Default is every 1 minute.

  evaluation_interval: 10s # Evaluate rules every 15 seconds. The default is every 1 minute.

  scrape_timeout: 10s

  # scrape_timeout is set to the global default (10s).



# Alertmanager configuration

alerting:

  alertmanagers:

  - static_configs:

    - targets:

      # - alertmanager:9093



# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.

rule_files:

  # - "first_rules.yml"

  # - "second_rules.yml"



# A scrape configuration containing exactly one endpoint to scrape:

# Here it's Prometheus itself.

scrape_configs:

  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.

  - job_name: 'sample-scrape'

    metrics_path: '/prometheus'

    # metrics_path defaults to '/metrics'

    # scheme defaults to 'http'.



    static_configs:

    - targets: ['localhost:8080']


  - job_name: 'dgp-scrape'

    metrics_path: '/crDgp/prometheus'

    # metrics_path defaults to '/metrics'

    # scheme defaults to 'http'.



    static_configs:

    - targets: ['localhost:9090']

tips:分别监控了两个项目，一个jobName是sample-scrape,项目地址和端口是localhost:8080 ,暴露的端点是 /prometheus，另一个是dgp-scrape ,地址和端口是 localhost:9090,暴露端点是 /crDgp/promethus

启动promethus项目

prometheus.exe --web.listen-address=0.0.0.0:8888 --web.enable-lifecycle

--web.listen-address=0.0.0.0:8888 表示启动在8888端口
--web.enable-lifecycle 表示允许使用managementapi

访问localhost:8888 查看页面

springboot1.x+promethus+grafana打造分布式监控系统

查看目标列表 status->targets

springboot1.x+promethus+grafana打造分布式监控系统

可以看到那些主机down了，那些是正常的

linux docker安装和启动项目

docker run -d --name prometheus -p 8888:9090 -m 500M -v /opt/soft/prometheus/prometheus.yml:/prometheus.yml -v /opt/soft/prometheus/data:/data prom/prometheus --config.file=/prometheus.yml --log.level=info

其他步骤和windows一致，不再赘述
