Prometheus 組件

官網： https://prometheus.io/

下載地址： https://prometheus.io/download/

官方文檔： https://prometheus.io/docs/prometheus/latest/getting_started/

Prometheus是一套開源的監控&報警&時間序列數據庫的組合，基于應用的metrics來進行監控的開源工具 。

更多信息請參考官網介紹： https://prometheus.io/docs/introduction/overview/

下載 & 安裝

官網下載速度太慢，我這里就沒有使用最新版本，而是從 http://cactifans.hi-www.com 下載了 prometheus-2.1.0的版本

通過指定配置文件prometheus.yml啟動Prometheus

配置文件官方說明： https://prometheus.io/docs/prometheus/latest/configuration/configuration/

默認情況下，Prometheus會監控自己本身。

查看采集到的性能指標

訪問 http://192.168.31.34:9090/metrics

太多了，真是沒法看，還好有個弱弱的圖形頁面 （待會整合到Grafana 中就方便看了）

訪問： http://192.168.31.34:9090/graph


選中某個指標，點擊Execute . 超多指標可以查看 …

配置文件

spring: application:name: springbootPrometheusGrafanamanagement: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}

實例化MeterRegistryCustomizer

方便起見，我們就在啟動類中實例化吧

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);}@BeanMeterRegistryCustomizer<MeterRegistry> configurer(@Value("${spring.application.name}") String applicationName) {return (registry) -> registry.config().commonTags("application", applicationName);}}

打包，上傳到服務器上

右鍵–Run As – Maven build ,輸入 clean package

服務器上啟動該jar即可

java -jar springbootPrometheusGrafana-0.0.1-SNAPSHOT.jar &

Prometheus 修改配置文件prometheus.yml 接入該工程

增加如下配置：

#SpringBoot應用配置- job_name: 'springbootPrometheusGrafana'scrape_interval: 5smetrics_path: '/actuator/prometheus'static_configs:- targets: ['192.168.31.34:8080']

重啟Prometheus

[root@artisan prometheus]# ./prometheus --config.file=prometheus.yml &

Grafana 組件

官網：https://grafana.com/
下載地址： https://grafana.com/grafana/download
入門：http://docs.grafana.org/guides/getting_started/

剛才也說了，Prometheus 的可視化功能比較弱，這里我們來接入Grafana 。

Grafana是一個跨平臺的開源的度量分析和可視化工具，可以通過將采集的數據查詢然后可視化的展示，并及時通知。它主要有以下六大特點：

  • 展示方式：快速靈活的客戶端圖表，面板插件有許多不同方式的可視化指標和日志，官方庫中具有豐富的儀表盤插件，比如熱圖、折線圖、圖表等多種展示方式；

  • 數據源：Graphite，InfluxDB，OpenTSDB，Prometheus，Elasticsearch，CloudWatch和KairosDB等；

  • 通知提醒：以可視方式定義最重要指標的警報規則，Grafana將不斷計算并發送通知，在數據達到閾值時通過Slack、PagerDuty等獲得通知；

  • 混合展示：在同一圖表中混合使用不同的數據源，可以基于每個查詢指定數據源，甚至自定義數據源；

  • 注釋：使用來自不同數據源的豐富事件注釋圖表，將鼠標懸停在事件上會顯示完整的事件元數據和標記；

  • 過濾器：Ad-hoc過濾器允許動態創建新的鍵/值過濾器，這些過濾器會自動應用于使用該數據源的所有查詢。
